We are offering triplex digital bidirectional analog receiver.Triplexer series is 131014901550nm single fiber optical device designed for digital bi-directional and analog receiver. It is suitable to use in the digitalanalog fttx application. Integrated with two kind of coupler, the first is 1310nm1490nm splitter and the second is 14901550nm filter.The transmitter section incorporates an advanced fpdfb laser diode can be operated up to 1.25gbs, the 1490nm receiver section incorporates an efficient ingaasinp pin photodiode, the 1550nm receiver is a broadcast, low distortion photodiode. The most compacted and cost-effective wdm can be provided in a single fiber. The triplexer can be built for a wide variety of data communicate applications to implement high-speed extends up to 2.5gbs signal rates, long distance up to 20km. 9125m diameter single mode fiber with an optional.
