graded index optical fibre cable" ITU-T G.652, "Characteristics of a single-mode optical fibre cable" Other standards specify performance criteria for fiber, transmitters, and receivers to be used together in conforming systems. Some of these standards are: 100 Gigabit Ethernet 10 Gigabit Ethernet Fibre Channel Gigabit Ethernet HIPPI Synchronous Digital Hierarchy Synchronous Optical Networking Optical transport network (OTN) TOSLINK is the most common format for digital audio cable using plastic optical fiber to connect digital sources to digital receivers.
