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.
