4E1 + 4GE 1+1 Fiber PDH Multiplexer
型号：LNK-PDH-E4G4-2SFP
►4Channel Ethernet interface is switch interface, support VLAN, can set to 4 channel logical isolation；
►E1 interface comply with G.703；
►The transmission
distance is up to 2-120Km
without interruption；
Overview
This device provides 1-4Channel E1 interface, master optical fiber interface and backup optical fiber interface, 1-4Channel 10M/100/1000M Ethernet interface (Line Rate 1000M) and 2 expansion interface. 4Channel Ethernet interface is switch interface, can support VLAN. 2 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). 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►Modular wide dynamic optical detector
►The device provides master optical fiber interface and backup optical fiber interface, Dual Optical Port backup function ensures that the work will never break
►Ethernet interface rate is 10M/100/1000M, half/full duplex auto- Negotiation
►4Channel 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
►1Channel PCM digital business phone (optional)
►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 1~2Channel asynchronous data, such as RS232/RS485/RS422/Manchester code;
►1~2Channel voice,1~4Channel switch , or two/four line audio and so on
►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
