FastEthernet refers to a set of network standards for data transfer speeds that exceed the original Ethernet speed of 10 megabits per second (mbps). Hardware and software that support FastEthernet can provide speeds up to 100 mbps. Original Ethernet is sometimes referred to as 10Base-T, for 10 mbps baseband data transmission over twist pair. “Twisted pair” is one type of copper Ethernet cabling used in networking. FastEthernet is also known as 100Base-T, though there are other designations as well for other types of cabling.
While FastEthernet improved network speed ten-fold, it is now only a mid-range Ethernet architecture. Gigabit Ethernet (GbE) operates ten times faster than FastEthernet, at speeds of 1 gigabit per second (gbps), or 1000Base-T, and faster. The Institute of Electrical and Electronics Engineers (IEEE) publication 802x sets the technical standards for LANs so that networking hardware is interoperable or compatible within its class. There are several different standards for each class of Ethernet LAN.
For example, standard Ethernet 10Base-T runs over twisted pair cables with a maximum distance of 328 feet (100 meters). 10Base-2 designates standard Ethernet over coaxial cable, or Thinnet. The maximum distance for this type of Ethernet is about 607 feet (185 meters). There are eight more types of cabling for standard Ethernet under the IEEE 802 specifications.
FastEthernet has five different cabling standards outlined by IEEE 802, with 100Base-X being a general designation. Ethernet cabling is defined by Category designations, dictated by its technical specifications. Hence, Category 5 cable, for example, is sometimes referred to as Cat-5 cable for short. FastEthernet includes the following standards and options:
- 100Base-FX – FastEthernet over dual multimode optical fiber cables
- 100Base-TX – Two shielded twisted pair cables, Category 4 grade
- 100Base-T – Two twisted pair cables
- 100Base-T2 – Two unshielded twisted pair cables, Category 3 or better
- 100Base-T4 – Four unshielded twisted pair cables, Category 3 or better
Gigabit Ethernet has its own classifications under IEEE 802, including 10Gigabit Ethernet with speeds up to 10-billion bits per second. This type of LAN uses optical fiber cabling and has a maximum distance of 984 feet (300 meters) for multimode fiber cable, and nearly 25 miles (40 kilometers) for single-mode optical cable.
Hardware for a faster LAN usually requires more initial investment than a slower one. However, if the speed is required, it pays for itself over time in productivity. On the other hand, a small business office may see a point in diminishing returns when considering an ultra-fast GbE over a less-expensive, but still very effective FastEthernet LAN.
Katika EasyTechJunkie, tumejitolea kutoa habari sahihi, ya kuaminika. Maudhui yetu yaliyoandikwa na wataalamu ni ya kweli-kuchunguzwa kwa ukali na inatokana na mamlaka ya kuaminika. Gundua jinsi tunavyotegemeza viwango vya juu zaidi katika kukupa maarifa ya kuaminika. FastEthernet ni mfumo wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao. Vifaa vya vifaa vya FastEthernet vinaweza kufikia kasi ya 100Mbps. Ethernet ya asili ni wakati mwingine inajulikana kama 10Base-T, kwa ajili ya 10 mbps baseband data maambukizi juu ya twist jozi. <unk>Twisted jozi<unk> ni aina moja ya shaba Ethernet cabling kutumika katika mitandao. FastEthernet pia inajulikana kama 100Base-T, ingawa kuna majina mengine pia kwa aina nyingine za kebo. Wakati FastEthernet kuboreshwa mtandao kasi mara kumi, ni sasa tu kati ya mbalimbali Ethernet usanifu. Gigabit Ethernet (GbE) ni moja ya njia za kuunganisha data kwa njia ya mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao wa mtandao. "Inteklia ya Uhandisi wa Umeme na Elektroniki (IEEE) kuchapishwa 802x inaweka viwango vya kiufundi kwa ajili ya LANs ili vifaa vya mitandao ni interoperable au sambamba ndani ya darasa lake. """ Kuna viwango kadhaa tofauti kwa kila darasa la Ethernet LAN. Kwa mfano, Ethernet 10Base-T inaendesha juu ya cables twisted jozi na umbali wa juu wa mita 328. "10Base-2 ni ""Ethernet juu ya coaxial cable"" (TIN)." Umbali wa juu wa Ethernet ni mita 185. Kuna aina nane za cable kwa ajili ya Ethernet kiwango chini ya IEEE 802 vipimo. FastEthernet ina viwango vitano tofauti vya waya vilivyoelezwa na IEEE 802, na 100Base-X kuwa jina la jumla. Ethernet cabling ni kufafanuliwa na Makundi ya majina, dictated na vipimo yake ya kiufundi. "Kabla ya ""Katiba 5"" inaweza pia kutumika kama ""Katika 5"" cable." FastEthernet ni pamoja na viwango vifuatavyo: 100Base-FX, FastEthernet juu ya mbili multimode fiber optic cables, 100Base-TX, mbili shielded twisted pair cables, Category 4 daraja, 100Base-T2 mbili twisted pair cables, Category 3 au bora, 100Base-T4 nne unshielded twisted pair cables, Category 3 au bora, na 4 unshielded twisted pair cables, Category 3 au bora. Aina hii ya LAN hutumia kebo ya fiber optic na ina umbali wa juu wa mita 984 kwa kebo ya fiber multimode, na karibu maili 25 kwa kebo ya single-mode. Vifaa kwa ajili ya LAN haraka kawaida inahitaji uwekezaji zaidi ya awali kuliko moja polepole. Hata hivyo, ikiwa kasi inahitajika, inajilipa yenyewe kwa muda katika uzalishaji. Kwa upande mwingine, ofisi ndogo ya biashara inaweza kuona uhakika katika kupungua kwa mapato wakati wa kuzingatia GbE ya haraka sana juu ya LAN ya FastEthernet isiyo na gharama kubwa, lakini bado ni ufanisi sana.
