Fox - F :  Fiber Optic Multiplexer (FOM)

Fox-F, Fiber Optic Multiplexer (FOM), provides the electrical to optical conversion of electronic communication and data signals. Fox-F simultaneously transmits and receives optical signals through optical fiber, and converts them back to original electrical signal in full duplex transmission.

 

Designed as a single unit (1U), 19"/23” rack mountable, 4 slots of a modular design at the rear of the chassis, Fox-F can either be equipped with T1/ E1, V.35, or Ethernet cards and may extend the service range up to 100 KM over fiber optic cable.
