RJ45 8 E1 PDH Fiber Optical Multiplexer Ethernet Multiplexing Auto - MDIX 19" Rack

 
RJ45 8 E1  PDH Fiber Optical Multiplexer Ethernet Multiplexing Auto - MDIX 19" Rack
 
Overview
 
 This device  provides 1-8*E1 interface, 1-4*10M/100M Ethernet interface (WireSpeed 100M) and 2 expansion interface. 4* Ethernet interface is switch interface, can support VLAN. 2expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data. 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
• Ethernet(Line Speed 100M) interface rate is 10M/100M, half/full duplex Auto-Nego
• E1 interface comply 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)
• Provide2expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data
• 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 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
