1.3FIBER OPTIC MEDIA INTERFACE MODULES

Cabletron Systems Fiber Optic Media Interface Modules provide a choice of six, twelve, or eighteen ports with ST connectors.

NOTE

The FOMIM-32/36/38 use 1300 nm wavelength transmitters and receivers (not the 850 nm specified by FOIRL) and should be used only with the Cabletron Systems Ethernet single mode transceiver, the FOT-F3.

1.3.1Distance and Cable Type

The FOMIMs support single mode fiber optic cable for sizes such as 8.3/125 ∝m, 8.7/125 ∝m, 9/125 ∝m, 10/125 ∝m, and 12/125 ∝m. The cable distance is dependent on the cable type and the overall system fiber optic budget. If the system budgets and timing constraints are met, then a distance of up to 5 kilometers is possible. You can also use 62.5/125 ∝m multimode cable with the FOMIM, but due to greater optical loss, signal distance is reduced to 2 km.
