4E1 + 4FE 1+1 Fiber PDH Multiplexer

型号:LNK-PDH-E4F4

Ethernet interface rate is 10M/100M, half/full duplex auto- Negotiation;

4Channel Ethernet interface is switch interface, support VLAN, can set to 4 channel logical isolation;

E1 interface comply with G.703;

The transmission distance is up to 2-120Km without interruption;

Overview

This device  provides 1-4Channel E1 interface, master optical fiber interface and backup optical fiber interface, 1-4Channel 10M/100M Ethernet interface (Line Rate 100M) and 2 expansion interface. 4Channel Ethernet interface is switch interface, can support VLAN. 2 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4 line E&M audio signal, switch signal, Ethernet signal (Bandwidth 2M). It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
