32E1+4GE PDH Fiber Multiplexer

View : 868
Type : PDH Multiplexer 1-64E1+ GE Fiber multiplexer
Description :

The device provides 1-32*E1 interface, 1-4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces.


This device is a point-to-point optical transmission device based on VLSI. The device provides 1-32*E1 interface, 1-4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces. 4* Ethernet interface is a switch interface, which can support VLAN. 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, dry contact signal, and 1-channel EOW phone can be optional. It is very flexible. It has an alarm function. The work is reliable and stable. It has low power consumption, high integration, and small size.
