Physical Isolation PDH Mux

8E1+4FE(Physical isolation)PDH Fiber Multiplexer

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 1-8 E1 interfaces primary and backup fiber optical interface connector 1-4 physical isolation 10/100M Fast Ethernet interface (independent four-wire speed 100Mtotal 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.
