Description

4E1 PDH Fiber Optical Multiplexers Singlemode Dual Fiber 20KM 19 Inch Rack

1-4E1 Fiber Optical Multiplexer is a kind of fiber-optic communication device which can use fiber to transport 1~4 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 a office phone port (optional) and 1-2 channel RS232 (optional), raising applied flexibility also in the meantime enlarge the utilization of the fiber optic
