DHODT-8-GE - PDH Multipelxer 8E1-GE PDH Multiplexer
This device “DHODT-8-GE” is the point-to-point optical transmission device developed on the basis of VLSI. The device provides 1~8*E1 interface, 1~4*10/100/1000M Ethernet interface (Wire Speed 1000M) and 2 expansion interfaces. The 1~4*Gigabit Ethernet interfaces (Optional). 1 expansion interface can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, dry contact signal, 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.
Key benefits:
² Based on self –copyright IC
² The Fiber bandwidth is up to 1.25G, Ethernet bandwidth is Wire Speed 1000M
² Ethernet interface rate is 10/100/1000M, half/full duplex Auto-Nego
² 1*Gigabit Ethernet interfaces
² Provide Console manage interface (RS232)
² E1 interface comply with G.703, adopts digital clock recovery and smooth phase-lock technology
² Uses standard 2 wire telephone (non-telephone handles) set as engineering order-wire hotline(optional)
² When optical lose signal, it can detect the remote device is power off or fiber is disconnected, and
indicates alarm by LED
² The local device can view the remote device working condition
² Provide 2 expansion interface, you can extend 1~2 channel asynchronous data, such as
RS232/RS485/RS422/Manchester code;
² Provide command the remote interface Loop Back, support local E1 Loop Back function, support
E1 LOS and AIS alarm ,ease line maintenance
² The transmission distance is up to 2-100Km without interruption
² Support SNMP manager (SNMP agent inside)
² AC 220V, DC-48V, DC24V can be optional
² DC-48V/DC24V power supply polarity detection function, Polarity-Free
