16E1+8FE PDH Fiber Multiplexer

This device provides 1-16*E1 interface, 1-8*10/100M Ethernet interface (Wire Speed 100M), and 1 expansion interface. 8* 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. It is very flexible. It has an alarm function. The work is reliable, stable, and low power consumption, high integration, small size. Provide Optional SNMP, CONSOLE, and Fiber 1+1 backup if needed.

● Based on self-copyright IC

● Modular wide dynamic optical detector

● Provide Optional Console management interface (RS232)

● ProvideOptional two fiber interface 1+1 protect（APS）function ,and ALS（Automatic Laser Shutdown/Reduction）function

● Ethernet interface rate is 10M/100M, half/full duplex Auto-Nego

● Ethernet package size support 1916 byte and 4 Ethernet port could be set separately, and ethernet bandwidth can be set based on multiple of 32K

● E1 interface complies with G.703, adopts digital clock recovery and smooth phase-lock technology

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