8E1+4FE PDH Fiber Multiplexer

View : 648
Type : Physical Isolation PDH Mux
Description :

Provide 1-8 E1 interfaces, primary and backup fiber optical interface connector, 1-4 channel 10/100M Fast Ethernet interface , as well as two business expansion interface.


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 channel 10/100M Fast Ethernet interface, as well as two business expansion interfaces. 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 is stable, and reliable, has low power consumption, high integration, small size.
