16Voice+8E1+4GE+4RS232 Fiber Multiplexer

View : 238
Type : multi service over fiber mux
Description :

The device provides 16 channel voice, 8 E1 interfaces, 4*10/100/1000M Ethernet interfaces, and four expansion interfaces.


The device provides 16 channel voice,8 E1 interfaces, 4*1000M Ethernet interface, and 4 expansion interfaces. 2 Extended service interfaces can be used as RS232 / RS485 / RS422 asynchronous data, voice signal, E & M 2/4 wire audio signals, digital signals transmission channel, the application is very flexible. Optional Console or SNMP management, 1+1 fiber backup for option.
