Product description
This PDH fiber multiplexer provides 1-16 Channel E1 interface, 1-4Channel 100M/1000M Ethernet interface,1 expansion interface, 1 channel order wire for optional. It supports Console management and SNMP management for optional.It has an alarm function. The work is reliable, stable, and low power consumption, high integration, small size.
Functions
•Based on self -copyright IC
• Ethernet interface rate is 100M/1000M, half/full duplex auto- adaptable
•4Channel Ethernet interface is switch interface, can set to 4 channel logical isolation(optional)
• E1 interface comply with G.703, adopts digital clock recovery and smooth phase-lock technology
•1 expansion interface can transmit 1-2 channels RS232/RS485/RS422 asynchronous data or 1-2 channels voice signal or 2/4 line E&M audio signal or 1-4 channel switch signal (optional)
•Provide RS232 Console management port and SNMP management port (optional)
•Provide two optical interfaces, dual optical 1+1 protection (APS), ALS (Automatic Laser Shutdown/Reduction) function: After detecting the optical fiber interruption of the optical path, make the optical transmission terminal have no output power, and then can automatically return to normal after fiber recovery. (optional)
•With anti-Ethernet loopback function (When the optical line loopback, Ethernet data will not be looped back, so that can effectively be preventing Ethernet unavailable caused by Ethernet loopback);
• When optical loses signal, it can detect the remote device is power off or fiber is disconnected, and indicates alarm by LED
•The transmission distance is up to 2-120Km without interruption
•AC 220V, DC-48V or AC+DC dual power supply can be optional
• DC-48V power supply polarity detection function, Polarity-Free
