4E1+4FE(Physical isolation) JHA-CPE4WF4

PDH Fiber Multiplexer

Overview

This series of equipment is the company developed the PDH fiber transmission dedicated VLSI developed on the basis of point to point optical transmission equipment. Provide 1-4 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 two business expansion interface. 2 Extended service interface can be used as RS232 / RS485 / RS422 asynchronous data , the application is very flexible. Optional one digital service telephone, the application is very flexible. With a sound alarm function, the whole stable, reliable, low power consumption, high integration, small size.
