      16E1+4GE PDH Multiplexer

      1-16E1 Fiber Optical Multiplexer is a kind of fiber-optic communication device which can use fiber to transport 1~16 E1 signal in the meantime efficiently and can test the used E1 automatically. The flexible circuit test and the indication function has a simple single panel form, which provides 1~4 10M/100M/1000M Ethernet ports(optional) and an office phone port (optional), raising applied flexibility also in the meantime enlarge the utilization of the fiber optic.The four GE ports are switching interfaces, 10M/100M/1000M self-adapting completely.

      Product description


      16E1+4GE PDH fiber optical Mux, is a point-to-point optical transmission equipment developed based on ultra large scale integrated circuit. It has perfect alarm function, 1 channel digital service telephone and 4 channel GE Ethernet port. 16 channel Ethernet port set as switch and dividing VLAN as well. Ethernet transmission rate is 10/100/1000M auto adapted. The device's electronic part is total digital circuit, to assure working steady, low power consumption, high integration and easy maintain.
