16E1+4FE (Physical isolation) PDH Fiber Multiplexer

View : 629
Type : Physical Isolation PDH Mux
Description :

It provides 1-16 E1 interfaces, primary and backup fiber optical interface connector, 1-4 physical isolation 10/100M Fast Ethernet interface (independent four-wire speed 100M, total bandwidth is 4*100M), as well as 2 business expansion interface.


The device provides 16 E1 interfaces, primary and backup fiber optical interface connectors, 4 physical isolation 10/100M Fast Ethernet interfaces (independent four-wire speed 100M,total bandwidth is 4*100M), as well as 2 business expansion interfaces. 2 extended service interfaces can be used as RS232/RS485/RS422 asynchronous data ports, a digital service telephone is optional, the application is very flexible. The device has a sound alarm function, it’s stable and reliable, and has low power consumption, high integration, small size.
