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.
