4E1+4FE (1+1 Fiber Backup) PDH Multiplexer

View : 551
Type : Optic 1+1 PDH Multiplexer
Description :

This device provides 4*E1 interfaces, 4*10/100M Ethernet interfaces (Wire Speed 100M), and 2 expansion interfaces.

Overview

This device provides 4*E1 interfaces, 4*10M/100M Ethernet interfaces (Wire Speed 100M), and 2 expansion interfaces. The Ethernet interface is a switch interface that can support VLAN. 2 expansion interfaces can be used as the transmission channel of RS232/485/422 asynchronous data. It is very flexible. It has an alarm function. The work is reliable, and stable, it has low power consumption, high integration, and a small size.
