1-16E1 PDH Multiplexer

LCD display 16E1+4FE PDH Fiber Multiplexer

This device has the console control ,provides the 1+1fiber path protection point to point optical transmission LCD display on the basic of our company development of the PDH optical transmission use the special VLSI and the SNMP NMS. The device  provides 1-16*E1 interface 1-4*10M/100M Ethernet interface (Wire Speed 100M) and 1 expansion interface. 4* Ethernet interface is switch interface can support VLAN. 1 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.
