4E1+4FE PDH Fiber Multiplexer YB-PDH

4E1+4FE PDH Fiber Multiplexer

4E1+4FE PDH Fiber Multiplexer Overview

 This device  provides 1-4*E1 interface, 1-4*10M/100M Ethernet interface (Wire Speed 100M) and 2 expansion interface. 4* Ethernet interface is switch interface, can support VLAN. 2 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data. It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
