N*64K V.35 Fiber Modem

View : 177
Type : V.35 fiber modem
Description :

This device provides one optical interface and one V.35 interface to achieve interface conversion, rate conversion and timeslot extraction from fiber to V.35 interface.

Overview

This device provides one optical interface and one V.35 interface to achieve interface conversion, rate conversion, and timeslot extraction from fiber to V.35 interface. When framed mode, the users can extract timeslot n*64K (n ≤ 31) data channel; When unframed mode, the data channel rate is 2.048Mbps. The device has an inter-set loop test function to facilitate the project launching and daily maintenance.

Features

Based on self-copyright IC 

Can detect the reason for optical signal loss is that the device power-off or transmission fiber broken 

The local device can force the remote device rate to follow it(valid when framed ) 

Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;

After strict testing and a practical verification system, completely comply with protocol ITU-T V.35, G.703, G.704

Have three Loop Back Mode: E1 interface Loop Back (ANA)、35 interface Loop Back(DIG)、Command the remote V.35 interface Loop Back(REM)

Have pseudo-random code test function, easily line opened, can be used as a 2M BER Tester

35 interface supports hot-plug, supports DTE or DCE device interconnection 

Provide 3 clock types: Internal clock, External clock, E1 line clock;

AC 220V, DC-48V, DC+24V, DC Power and Polarity-Free
