1.3 THE FOT-F3 FIBER OPTIC TRANSCEIVER
Connections
The Cabletron Systems FOT-F3 Fiber Optic Transceiver (Fiber Optic Medium Attachment Unit or FOMAU)
(Fig. 1-1) easily connects two active Ethernet devices through a fiber optic link segment. Devices such as repeaters, multiport repeaters, multiport transceivers or host systems can be connected using fiber optic cable.
The FOT-F3 is fully compatible with IEEE 802.3 and uses the same signaling specified in FOIRL specifications. It provides the flexibility to connect to networks using Ethernet Version 1, Version 2, and/or IEEE 802.3 equipment through an AUI port. However, the FOT-F3 uses 1300 nm wave-length optical transmitters and receivers (not the 850 nm specified by FOIRL) and should be used only with Cabletron Systems' Ethernet single mode products such as the FOMIM-36, FOMIM-32, and the FOMIM-38.
