8E1 + 4FE 1+1 Fiber PDH Multiplexer
Model:LNK-PDH-E8-4F-2SFP
►Ethernet interface rate is 10M/100M, half/full duplex auto- adaptable
Overview
This device is the point-to-point optical transmission device developed on the basis of VLSI. The device provides 1-8 Channel E1 interface, 1-4 Channel 10M/100M Ethernet interface (Line Rate 100M) and 2 expansion interfaces. 4 Channel Ethernet interface is switch interface, can support VLAN. 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4 line E&M audio signal, switch signal, Ethernet signal (Bandwidth 2M).1 Channel digital business phone can be optional. It is very flexible. It has alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
Features
►Based on self-copyright IC►The bandwidth is up to 1.5G, can save line sources
►Ethernet interface rate is 10M/100M, half/full duplex auto- adaptable
►4 Channel Ethernet interface is switch interface, support VLAN, can set to 4 channel logical isolation
►E1 interface comply with G.703, adopts digital clock recovery and smooth phase-lock technology
►1 Channel PCM digital business phone (optional)
►Provide Console management interface
►When optical lose signal, it can detect the remote device is power off or fiber is disconnected, and indicates alarm by LED
►The local device can view the remote device working condition
►Provide 2 expansion interface, you can extend 1~2 Channel asynchronous data, such as RS232/RS485/RS422/Manchester code;
►1~2 Channel voice, 1~2 Channel E1，1~4 Channel switch , or Provide command the remote interface Loop Back, ease line maintenance
►The transmission distance is up to 2-120Km without interruption
►AC 220V, DC-48V, DC24V can be optional
►DC-48V/DC24V power supply polarity detection function, Polarity-Free
