v 35 Fiber Optical Modem
Compatible with V.35 Standard DB25 v 35 Fiber Modem
Description:
This device provides one fiber interface and one V.35 interface to achieve interface conversion, rate conversion and timeslot extraction from fiber to V.35 interface. When unframed mode,The data channel rate is 2.048Mbps. The device has inter-set loop test function to facilitate the project launching and daily maintenance.
Function and Characteristic
Based on self -copyright IC
Can detect the reason of optical signal losing is that the device power-off or transmission fiber broken
The local device can forced the remote device rate follow it(valid when framed )
