8E1+4GE PDH Fiber Multiplexer

This device is a point-to-point optical transmission device developed based on VLSI. The device provides 1-8*E1 interface, 1-4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces. 4* Ethernet interface is a switch interface, that can support VLAN. 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, dry contact signal, and 1-Channel digital business phone can be optional. It is very flexible. It has an alarm function. The work is reliable, stable, and it has low power consumption, high integration, and small size.

● Based on self-copyright IC;

● Uses standard 2 wire telephone(non-telephone handles) set as engineering order-wire hotline (optional);

● When the optical loses signal, it can detect the remote device is powered off or the fiber is disconnected and indicates an alarm by LED;

● The local device can view the remote device’s working condition;

● Provide 2 expansion interface, you can extend 1~2Channel asynchronous data, such as RS232/RS485/RS422/Manchester code (optional);

● Provide command the remote interface Loop Back, support local E1Loop Back function, support E1 LOS and AIS alarm, ease line maintenance;

● The transmission distance is up to 2-100Km without interruption (Default FC dual fiber single mode 20km);

● Support SNMP manager (SNMP agent inside) (optional);

● AC 220V, DC-48V, DC24V can be optional;

● DC-48V/DC24V power supply polarity detection function, Polarity-Free.
