Product Description

This device is the point-to-point optical transmission device developed on the basis of VLSI. The device provides 1-32*E1 interface, 1-4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces. 4* Ethernet interface is switch interface, can support VLAN. 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, dry contact signal, 1Channel 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.

Functional Properties

◆ Based on self -copyright IC

◆ The Fiber bandwidth is up to 1.5G, Ethernet bandwidth is Wire Speed 1000M

◆ Ethernet interface rate is 10/100/1000M, half/full duplex Auto-Nego

◆ 4*Ethernet interface is switch interface, support VLAN, can set to 4 channel logical isolation

◆ Provide Console manage interface (RS232)

◆ Provide two fiber interface(SFP module), 1+1 protect（APS）function

◆ 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)

◆ 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;

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

◆ The transmission distance is up to 2-100Km without interruption

◆ Support SNMP manager (SNMP agent inside)

◆ AC 220V, DC-48V, DC24V can be optional

◆ DC-48V/DC24V power supply polarity detection function, Polarity-Free
