    16E1+GE 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 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.

    Product description


    16E1+GE 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 1 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.
