High definition 4 Channel Multiplexer - 8E1+LCD Display +SNMP JHA-C2P-E8bF4R2 PDH Fiber Multiplexer – JHA

8E1+LCD Display +SNMP JHA-C2P-E8bF4R2

PDH Fiber Multiplexer

Overview

This device has the console control, provides the 1+1 fiber back-up 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 1-8*E1 interface, 1-4*10/100M Ethernet interface (Wire speed 100M) and 2 expansion interface. 4Channel 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
