CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application No. 62/312,734, filed Mar. 24, 2016, which application is hereby incorporated by reference in its entirety. 
     
    
     TECHNICAL FIELD 
       [0002]    The present disclosure relates generally to fiber optic connection devices and housings. 
       BACKGROUND 
       [0003]    There is an increased need to expand optical fiber or cable in rooms of existing buildings, such as residential homes or commercial buildings, to provide data communication with electronic devices. A system and method that enables an installer to easily route optical fiber or cable to make connections that would be aesthetically pleasing in the home, while also protecting the connections, is desirable. 
       SUMMARY 
       [0004]    Fiber optic wall jacks may include connector covers for protecting mating fiber optic connectors or adapters that prevent light emissions from the fiber-optics of the connectors when the adapter is open (i.e., when no mating connector is inserted). The connector covers provide protection of the open end from environmental contamination. The present disclosure relates to light-blocking connector covers that block the opening through which the light signal is transmitted when in a closed position and allow open access to the mating connectors when in an open position. 
         [0005]    A fiber optic wall jack and features thereof are described. The fiber optic wall jack can be adapted to protect a junction of two mechanically mated fiber optic connectors in an indoor environment such as a building. In one example, the building can be single family and/or multi-dwelling units. The fiber optic wall jack can be mounted directly to a wall surface. The fiber optic wall jack is arranged and configured to allow access to either side of an optical adapter located therein. The fiber optic wall jack can be configured to provide for pre-positioning of a single connector in the optical adapter and to provide protection of a non-connectorized open end of the optical adapter from environmental contamination and escape of laser light. The non-connectorized open end of the optical adapter positioned within the fiber optic wall jack can be accessible such that a subscriber drop can be added at a future date. 
         [0006]    The present disclosure enables an optical fiber or cable to be installed at a customer&#39;s premises to make connections quickly and safely.

     DETAILED DESCRIPTION 
       [0026]    A feature of the present disclosure relates to a fiber wall jack for making telecommunication connections within a new or existing building. A communication line such as an optical fiber cable can be installed in rooms of an existing building to serve electronic devices. The line can be mounted to a fiber wall jack that is positioned on the walls of the room along the baseboards, around door frames, or in corners, where the visual impact is acceptable and the cost of installation is reasonable. 
         [0027]    The fiber wall jack may have a slim profile for flexible mounting along walls in a customer&#39;s premises. The fiber wall jack may be mounted using various attachment means including, but not limited to, mechanical fasteners, adhesives, snap-fit connection, combinations thereof, or the like. It will be appreciated that other methods of securement may be used. The fiber wall jack can also have a symmetrical design that allows for connector entry on both ends of the fiber wall jack. The fiber wall jack can include a fiber optic adapter compatible with LP, SC type connectors, or other types of connectors. The connections of the fiber wall jack can be protected by shutter covers pivotally mounted on opposite ends of the fiber wall jack to provide a seal. 
         [0028]    An example fiber wall jack  10  is depicted in  FIG. 1 . This fiber wall jack  10  includes a housing  12  that defines a major axis  14  and a minor axis  16  (see  FIG. 2 ). The major axis  14  and the minor axis  16  can be perpendicular relative to one another. The example housing  12  is shown symmetrical about the major axis  14  and the minor axis  16 . The housing  12  defines a first end  18  and a second opposite end  20  that may be intersected by the major axis  14 . The example housing  12  is shown elongated between the first and second ends  18 ,  20 . The example housing  12  has as symmetrical design, although alternatives are possible. 
         [0029]    The housing  12  may be may be made from any material including, but not limited to, metals, plastics, ceramics, acrylics, rubber, combinations thereof, or any other solid material. Preferably the housing  12  is made from a molded plastic. 
         [0030]    Referring to  FIGS. 2-7 , the example housing  12  also includes a first side  22  and a second side  24  that are intersected by the minor axis  16 . The first and second sides  22 ,  24  extend between the first end  18  and the second end  20  of the housing  12 . 
         [0031]    The housing  12  also defines a first connector chamber  26  (see  FIG. 4 ) located between the minor axis  16  and the first end  18  of the housing  12  and a second connector chamber  28  (see  FIG. 7 ) located between the minor axis  16  and the second end  20  of the housing  12 . 
         [0032]    The example housing  12  includes a base  30  that has a length L that extends from the first end  18  of the housing to the second end  20  of the housing  12 . The base  30  also has a width W that extends from the first side  22  of the housing  12  to the second side  24  of the housing  12 . The depicted base  30  defines an adapter mount  32  including adapter retention walls  45  (see  FIG. 7 ) with flanges  49  (see  FIG. 9 ). The adapter mount  32  is located at an intersection  34  between the major axis  14  and the minor axis  16 . The adapter mount  32  is arranged and configured to receive an optical fiber adapter  36  that snaps into the adapter mount  32  between the adapter retention walls  45 . The flanges  49  of the adapter retention walls  45  help to keep the optical fiber adapter  36  from sliding out lengthwise along the major axis  14 . 
         [0033]    In  FIGS. 4-6 , a fiber optic connector  38  is shown having an SC-type intermatability profile. As such, the fiber optic connector  38  can be adapted to be received within an SC-type fiber optic adapter  36  that is used to couple two of the connectors together to provide an optical connection thereinbetween. 
         [0034]    In one example, a fiber optic connector  38   a  can be inserted within the fiber optic adapter  36  such that exterior shoulders of the connector  38   a  are engaged (i.e., abuts against, mated to) by latches of the fiber optic adapter  36  to retain the fiber optic connector  38   a  within the fiber optic adapter  36 . To release the fiber optic connector  38   a  from the fiber optic adapter  36 , an outer release sleeve of the fiber optic connector  38   a  can be slid rearwardly to cause the latches of the fiber optic adaptor  36  to disengage from the exterior shoulders such that the fiber optic connector  38   a  can be withdrawn from the fiber optic adapter  36 . An example fiber optic adapter is disclosed at U.S. Pat. No. 5,317,663 which is hereby incorporated by reference in its entirety. It will be appreciated that a variety of other adapters may be used. 
         [0035]    The example housing  12  includes a first cover  40  that cooperates with the base  30  to enclose the first connector chamber  26  of the housing  12 . The first cover  40  may be pivotally movable about a first pivot axis  42  between an open position (see  FIG. 4 ) and a closed position (see  FIG. 1 ). The first pivot axis  42  can be located adjacent to the minor axis  16  and forms a first pivot connection  48 . 
         [0036]    As used herein, the term, “adjacent” and variants thereof, in this context, means that the first pivot axis  42  is closer to the minor axis  16  than to the first end  18 . The housing  12  also includes a second cover  44  that cooperates with the base  30  to enclose the second connector chamber  28  of the housing  12 . The second cover  44  can be pivotally movable about a second pivot axis  46  between an open position (see  FIG. 7 ) and a closed position (see  FIG. 1 ). The second pivot axis  46  can be located adjacent to the minor axis  16  and forms a second pivot connection  50 . 
         [0037]    As used herein, the term, “adjacent” and variants thereof, in this context, means that the second pivot axis  46  is closer to the minor axis  16  than to the second end  20 . 
         [0038]    The first and second covers  40 ,  44  may be made from any material including, but not limited to, metals, plastics, ceramics, acrylics, rubber, combinations thereof, or any other solid material. The first and second covers  40 ,  44  can each help to prevent dust from entering the first and second connector chambers  26 ,  28  and light from shining out. 
         [0039]    The first and second covers  40 ,  44  are rotatably mounted on opposite sides of the fiber wall jack  10  at respective first and second ends  18 ,  20  of the housing  12 . As depicted, the first and second pivot axis  42 ,  46  of the first and second covers  40 ,  44  are parallel to each other. First and second pivot connections  48 ,  50  can each be formed by a pivot pin (e.g., see pins  80  integrated with the covers  40 ,  44 ) extending therethrough, or alternatively it can be formed in any other known manner. 
         [0040]    The fiber optic adapter  36  can define a first connector port  52  (see  FIG. 7 ) accessible from the first connector chamber  26  and a second connector port  53  (see  FIG. 10 ) accessible from the second connector chamber  28 . 
         [0041]      FIG. 7A  illustrates one example fiber optic assembly  9  which is suitable for practicing aspects of the present disclosure. The fiber optic assembly  9  includes the fiber optic connector  38   b . The example fiber optic connector  38   b  includes a ferrule  27  and a fiber  7  secured to the ferrule  27 . In one example, the ferrule  27  is generally cylindrical. In one example, the ferrule  27  has a diameter in the range of 1-3 millimeters or in the range of 1.25-2.5 millimeters. Example ferrules include SC ferrules and LC ferrules. 
         [0042]    The ferrule  27  defines a ferrule bore  29  that extends through the ferrule  27 . The fiber  7  includes a first portion  31  secured within the ferrule bore  29  and a second portion  33  that extends rearwardly from a rear end of the ferrule  27 . The first portion  31  of the fiber  7  is preferably secured by an adhesive (e.g., epoxy) within the ferrule bore  29  of the ferrule  27 . The interface end  35  preferably includes a processed end face accessible at a front end of the ferrule  27 . The ferrule  27  includes a ferrule hub  37  mounted to the rear end of the ferrule  27 . Generally, the ferrule  27  and ferrule hub  37  are secured together by convenient methods including press fit or adhesive mounts. The fiber optic connector  38  can be one of a variety of well-known connector types, including SC, FC, ST, LX.5, LC, and others. 
         [0043]    The ferrule  27  is preferably constructed of a relatively hard material capable of protecting and supporting the first portion  31  of the fiber  7 . In one embodiment, the ferrule  27  has a ceramic construction. In other embodiments, the ferrule  27  can be made of alternative materials such as Ultem, thermoplastic materials such as Polyphenylene sulfide (PPS), other engineering plastics or various metals. In one example, the ferrule  50  can be a single fiber ferrule such as a ferrule for and SC connector, and ST connector, or an LC connector. While  FIG. 7A  depicts a single fiber ferrule, aspects of the present disclosure are also applicable to multi-fiber ferrules such as MT-ferrules and MPO ferrules. A typical multi-fiber ferrule can have a generally rectangular shape and can support a plurality of fibers supported in one or more rows by the multi-fiber ferrule. In certain examples, a fiber optic adapter compatible with multi-fiber connectors can be mounted in the housing  12 . 
         [0044]    When two fiber optic connectors  38   a ,  38   b  are latched within the first and second connector ports  52 ,  53  of the fiber optic adapter  36 , ferrules of the fiber optic connectors  38   a ,  38   b  fit within respective first and second ends  39  of a split sleeve  41  and are thereby held in co-axial alignment with one another. 
         [0045]    In the closed position, the first connector port  52  is completely covered by the first cover  40  and the second port  53  is completely covered by the second cover  44 . The housing  12  can have a depth d 1  that extends perpendicularly relative to the length L and the width W from the base  30  to a top surface  54  of the housing  12 . The housing  12  of the fiber wall jack  10  has a low, slim profile to provide for less physical interference when mounted. For example, the fiber wall jack  10  will not stick out far form a wall surface and thus will be less likely to be bumped. In one example, the housing  12  can have a length L of at least 110 mm, a width W within a range of 20-30 mm, and a depth d 1  within the range of 10-25 mm, although alternatives are possible. In certain examples, the depth d 1  is less than the width W and the width W is less than the length L. 
         [0046]    The first cover  40  can include a first cover first side wall  56  that defines a portion of the first side  22  of the housing  12  that corresponds with the first connector chamber  26 . The first cover  40  may also include a first cover second side wall  58  that defines a portion of the second side  24  of the housing  12  that corresponds with the first connector chamber  26 . 
         [0047]    The first cover first and second side walls  56 ,  58  may each have a dimension d 2  that extends a majority of the depth d 1  of the housing  12  such that when the first cover  40  is in the open position, side access to the first connector port  52  within the first connector chamber  26  is provided. For example, the first cover first and second side walls  56 ,  58  respectively form a majority of the first and second sides  22 ,  24  of the housing  12  corresponding with the first connector chamber  26  such that when the first cover  40  is in the open position a majority of the first and second sides  22 ,  24  of the housing  12  is removed to allow open side access into the first connector chamber  26 . As such, there is no interference with the ability to access the fiber optic connector  38   a ,  38   b.    
         [0048]    The first cover  40  of the housing  12  further includes a first end wall  60  that extends a majority of the depth d 1  such that when the first cover  40  is in the open position end access to the first connector port  52  within the first connector chamber  26  is provided. The first end wall  60  can be integral with (e.g., forming in one piece with) or coupled to, the first cover first and second side walls  56 ,  58 , although alternatives are possible. 
         [0049]    The second cover  44  includes a second cover first side wall  62  that defines a portion of the first side  22  of the housing  12  that corresponds with the second connector chamber  28 . The second cover  44  also includes a second cover second side wall  64  that defines a portion of the second side  24  of the housing  12  that corresponds with the second connector chamber  28 . The second cover first and second side walls  62 ,  64  each have a dimension d 3  that extends a majority of the depth d 1  of the housing  12  such that when the second cover  44  is in the open position, side access to the second connector port within the second connector chamber  28  is provided. As such, there is no interference with the ability to access the fiber optic connector therein. 
         [0050]    The second cover  44  further includes a second end wall  66  (see  FIG. 7 ) that extends a majority of the depth d 1  such that when the second cover  44  is in the open position end access to the second connector port within the second connector chamber  28  is provided. The second end wall  66  can be integral with (e.g., forming in one piece with) or coupled to, the second cover first and second side walls  62 ,  64 , although alternatives are possible. 
         [0051]    The first and second covers  40 ,  44  can each include a dust gasket  68  (e.g., seal member) to seal and help prevent dust from entering the first and second connector chambers  26 ,  28 . The first and second covers  40 ,  44  each carry the dust gasket  68  within an opening  13  (e.g., receptacle) (see  FIG. 9 ) defined by two arms  15  (e.g., walls) extending from an inner surface  19  of the respective first and second covers  40 ,  44  across the width of the housing  12  such that when in the closed position the dust gasket  68  helps to prevent dust, liquid, or other elements from entering the first and second connector chambers  26 ,  28 . 
         [0052]    Although the dust gasket  68  is shown near the respective first and second ends  18 ,  20  of the base  30 , the dust gasket  68  can be located further inside the respective first and second connector chambers  26 ,  28  when the first and second covers  40 ,  44  are in the closed position. The dust gasket  68  can have a resilient/elastomeric construction and can define self-closing slots or openings for receiving fiber optic cables corresponding to the fiber optic connectors. The dust gasket  68  may be comprised of a gel material, although alternatives are possible. For example, the dust gasket  68  may be formed of a foam material. 
         [0053]    In other examples, the first and second covers  40 ,  44  can be used to help secure optical fiber  11  within the first and second connector chambers  26 ,  28 . In the closed position, the first and second covers  40 ,  44  can block laser radiation exiting the fiber optic adapter  36  when only one connector is plugged into the adapter thereby preventing it from harming a person&#39;s eyes. 
         [0054]    Referring to  FIGS. 8-10 , exploded views of the fiber wall jack  10  are depicted. The base  30  includes a side wall  70  that has a base depth d 4  that extends a minority of the depth d 1  of the housing  12 . The side wall  70  of the base  30  has a middle section member  72  that extends the full depth d 1  of the housing  12 . The fiber wall jack  10  can further include a retention clip  74  mountable between the middle section member  72  and the adapter mount  32 . The middle section member  72  defines a mounting structure that has latch arms  76  adapted to engage (i.e., abuts against, mated to snap-over) an upper portion  17  of the retention clip  74  to help secure the retention clip  74  on the base  30  of the housing  12 . 
         [0055]    In one example, the retention clip  74  includes lip portions  78  that extend inwardly from opposite side edges thereof to capture/overlie a pivot pin  80  of the first and second covers  40 ,  44  when respectively associated therewith. The pivot pin  80  of the first and second covers  40 ,  44  can be integral with (e.g., forming in one piece with) or coupled to, the first and second covers  40 ,  44 , although alternatives are possible. The opposing lip portions  78  of the retention clip  74  and the pivot pins  80  of the first and second covers  40 ,  44  together form respective first and second attachment mechanisms. The lip portions  78  of the retention clip  74  respectively mount the first and second covers  40 ,  44  for pivotable movement about the pivot pins  80 . 
         [0056]    The retention clip  74  also includes a pair of two spaced apart legs  82  with latch members  84  (e.g., hooks) to secure the retention clip  74  on the base  30  of the housing  12 . The base  30  defining apertures  86  (see  FIG. 9 ) for receiving the latch members  84  of the legs  82  of the retention clip  74 . 
         [0057]    The fiber wall jack  10  may optionally include a plate  21  defining recesses  23  located on opposite sides of the plate  21  and opposing flanges  47  (see  FIG. 10 ). The plate  21  can be configured to rest upon the adapter mount  32  between the fiber optic adapter  36  and retention clip  74 . The flanges  47  help to provide support for the pivot pins  80  which are captured between lip portions  78  of the retention clip  74  and the flanges  47  of the plate  21 . The plate  21  can rest on upper ends of the adapter retention walls  45 . The plate  21  may be H-shaped with recesses  23 , although alternatives are possible, to provide spacing for the latch arms  76  of the middle section member  72  and the upper portion of the retention clip  74  when the retention clip  74  is attached or mounted to the base  30 . The plate  21  may be a center foam piece to help seal the first and second cover  40 ,  44  hinge area. Although the retention clip  74  is shown secured to the base  30  of the housing  12  by snap fit connection, alternatives are possible. It will be appreciated that many variations in the clip design other than the embodiment disclosed herein will be apparent to those skilled in the art and are contemplated within the scope of the present invention. 
         [0058]    The clip of the present disclosure may be constructed in various sizes according to their intended function. The clips can be made from metals, plastics, ceramics, acrylics, rubber, combinations thereof, or any other solid material. The clips may also be cast or machined from solid polymeric materials. 
         [0059]    Referring to  FIG. 11 , a perspective end view of the fiber wall jack  10  is depicted. The first and second covers  40 ,  44  each include respective first and second lock protrusions  88 ,  90  (see  FIG. 7 ) arranged on the first and second end walls  60 ,  66  respectively. Although the first cover  40  is shown, it will be appreciated that similar features are applicable to the second cover  44 . The base  30  includes first and second latch portions  92 ,  94  (see  FIG. 13 ) at respective first and second ends  18 ,  20  that each define first and second latch spaces  96 ,  98  for respectively receiving the first and second lock protrusions  88 ,  90  of the first and second covers  40 ,  44  (e.g., via a snap-fit) when in the closed position. The first lock protrusion  88  of the first cover  40  and the first latch portion  92  of the base  30  together forms a first latching end  100  when the first cover  40  latches down over the first end  18  of the base  30 . The second lock protrusion  90  of the second cover  44  and the second latch portion  94  of the base  30  together forms a second latching end  102  when the second cover  44  latches down over the second end  20  of the base  30 . It is to be understood that a variety of different ways may be used for securing the first and second covers  40 ,  44  to the base  30 . For example, the first and second covers  40 ,  44  can be attachable to the base  30  via at least one of a snap fit, friction fit, a latch fit, a sliding fit, a fastener, a screw, and/or a hinge. 
         [0060]    The first and second latch portions  92 ,  94  of the base  30  may be formed from any suitable material with plastic being a desirable material. The first and second latch portions  92 ,  94  can be formed as a single piece with the base  30  and when formed from plastic, can be integrally molded. 
         [0061]    The first and second lock protrusions  88 ,  90  may be formed from any suitable material with plastic being a desirable material. The first and second lock protrusions  88 ,  90  can be formed as a single piece with the first and second covers  40 ,  44  respectively and when formed from plastic, can be integrally molded. 
         [0062]    Turning again to  FIG. 9 , the base  30  of the housing  12  has a bottom wall  104  with a mounting surface  106  adapted to be adhesively secured to a wall surface (not shown) through an adhesive bonding layer  108 , although alternatives are possible. Many types of adhesives are suitable for this purpose. For example, the adhesive bonding layer  108  may be a double-sided polyurethane foam tape. In another example, the adhesive bonding layer  108  may be a pressure sensitive double-sided acrylic tape. Where using a double-sided tape, one side may be bonded to a wall surface, and the other side may be bonded to the mounting surface  106  of the fiber wall jack  10 . In certain examples, a liquid or semi-liquid adhesive may be applied to the mounting surface  106  rather than a tape. The adhesive bonding layer  108  may be additionally provided with a release liner (not shown) for protecting the adhesive prior to application. The release liner may be made from a variety of materials, such as polyethylene, provided they are compatible with the underlying adhesive bonding layer  108 . 
         [0063]    In other examples, the base  30  can define at least one mounting hole  110  configured to allow a fastener device  112  (e.g., a nail, screw or bolt) to slide in the mounting hole  110  to anchor the fiber wall jack  10  to a wall surface. The mounting hole  110  is angled at an oblique angle relative to the mounting surface  106  of the base  30 . It will be appreciated that multiple mounting techniques may be used in conjunction with one another or separately. The adhesive bonding layer  108  may also act as a dirt trap within opening  25  (see  FIG. 5 ) defined in the base  30 . The opening  25  can be used to receive larger fasteners such as bolts or screws. When a screw passes through the opening  25  and into a wall, debris generated by screwing or drilling is captured or contained by the adhesive bonding layer  108 . 
         [0064]    Referring to  FIGS. 5-7, 19, 23 and 24  one or more channels  114  can be formed in the base  30  of each of the first and second connector chambers  26 ,  28 . The one or more channels  114  are shown with a center channel  114   a  and side channels  114   b  on opposite sides thereof. The side channels  114   b  are angled relative to the major axis  14  and the center channel  114   a  is parallel relative to the major axis  14 , although alternatives are possible. The side channels  114   b  are configured to provide a transition to respective sides of the  22 ,  24  of the fiber optic jack  10 . The center  114   a  channel is configured to provide a transition to the bottom wall  104  of the base  30  and over to either side  22 ,  24  thereof.  FIGS. 14-17  show another example configuration of the channels  114  which are all parallel to the major axis  14 . The benefit or advantage of having an angled channel is that it allows for the ability to translate the optical fiber out without having to make an abrupt bend when routing the optical fiber  11  out of the fiber wall jack  10 . 
         [0065]    As depicted, only the first connector chamber  26  is shown, but the second connector chamber  28  includes similar features and advantages. Each of the channels  114  may terminate adjacent a bend radius surface  116  that respectively provides a transition from a front surface  118   a ,  118   b  (see  FIG. 19 ) of the respective first and second connector chambers  26 ,  28  to the base  30  of the housing  12 . The bend radius surface  116  can provide a transition down to a location coplanar with the bottom wall  104  of the base  30  such that the optical fiber  11  can be routed to a baseboard of a wall. In certain examples the optical fiber  11  can be routed from transition through a wall where a hole is provided in the wall. 
         [0066]    In  FIG. 14 , the optical fiber  11  is shown routed through a center channel  114  over the bend radius surface  116  and curves under at least one of the latch portions  92  of the base  30 , although alternatives are possible. For example, the optical fiber  11  can be routed straight out perpendicularly to a wall surface to be routed therein. The bend radius surface  116  is within the first connector chamber  26  such that a loop of the optical fiber  11  can be therein to prevent any outside snag thereon. The optical fiber  11  can be fixed to a wall along a base board with attachment means, such as, adhesive, staples, etc. 
         [0067]    The second connector chamber  28  shows a configuration of the optical fiber  11  that is routed over a bend radius surface  116  and extends straight out a center channel  114  of the second connector chamber  28  without running underneath the latch portion  94  of the base  30  to be placed along a baseboard of a wall. It will be appreciated that other variations for routing the optical fiber  11  from the first and second connector chambers  26 ,  28  may be used such that multiple paths are feasible for routing the optical fiber  11  along a base board. The optical fiber  11  may be routed through a side channel  114  (e.g., edge, corner) or a center channel  114  of the first and second connector chambers  26 ,  28 . 
         [0068]    In certain examples, the optical fiber  11  can be anchored to the fiber wall jack  10  using a tie  43  (see  FIG. 5 ) (e.g., zip tie, etc.) that can be secured through tie down locations  120  (e.g., openings) defined in the base  30 . The tie  43  can wrap around channels  114  of the base  30  to anchor the optical fiber  11 . The fiber wall jack  10  includes a gap between the bottom wall  104  and the adhesive bonding layer  108  such that the tie  43  may be wrapped through and around the tie down locations  120  without interference. 
         [0069]    Referring to  FIGS. 18-27 , both a side view and isometric views are depicted to illustrate installation steps.  FIGS. 18 and 19  show the fiber wall jack  10  with the first and second covers  40 ,  44  in the open position. The fiber optic connector  38   b  is shown prior to being inserted into a connector port.  FIG. 20  shows the fiber optic connector  38   b  inserted into the connector port of the second connector chamber  28 .  FIG. 21  shows the first and second covers  40 ,  44  in the closed position.  FIG. 22  shows the fiber optic connector  38   a  prior to being inserted into the connector port  52  of the first connector chamber  26 .  FIG. 23  shows the fiber optic connector  38   a  prior to insertion with the first cover  40  in the open position.  FIGS. 24 and 25  show the fiber optic connector  38   a  installed into the connector port  52  of the first connector chamber  26 .  FIGS. 26 and 27  show the fiber optic connectors  38   a ,  38   b  installed in the fiber wall jack  10  with the first and second covers  40 ,  44  in the closed position. 
         [0070]    The principles, techniques, and features described herein can be applied in a variety of systems, and there is no requirement that all of the advantageous features identified be incorporated in an assembly, system or component to obtain some benefit according to the present disclosure. 
         [0071]    From the forgoing detailed description, it will be evident that modifications and variations can be made without departing from the spirit and scope of the disclosure.
Aspects and techniques of the present disclosure relate generally to fiber wall jacks including connector covers for protecting mating fiber optic connectors or adapters that prevent light emissions from the fiber-optics of the connectors when the adapter is open (i.e., when no mating connector is inserted). The connector covers providing protection of the open end from environmental contamination.
