Universal Fiber Optical Multiplexer (FOM)
U-FOM is designed to provide point to point optical
transmission for multiplexing tributary electrical
and/or optical signals. It simultaneously transmits and
receives optical signals through optical fiber, and
converts them into original electrical signal in full
duplex transmission for telephone, video and data
transmission in the mean time.
Designed as a single unit (1U), 19”/23” rack mountable,
it supports 4 slots of modular-designed tributary module
(card) at the rear side of the chassis. T1/E1, V.35,
Ethernet and Giga-bit Ethernet tributary cards are all
available for U-FOM, which may extend the service range
up to 40 km over fiber optic cable.
