Isolator Polarization Beam Combiner/Splitter(IPBC/IPBS)
Description
The Isolator Polarization Beam Combiner & Splitter is a hybrid device of isolator and Polarization Beam Combiner & Splitter, in intergrated component , which combines two orthogonal polarization signals into one output fiber. and blocks the reflected light from the terminal.PBC/PBS is widely applied in Fiber Optics Current Transducer(Foct), Gyro, Raman Amplifier,EDFA,for the extremely performence of low insertion loss, high extinction ratio, high environment stability and reliability
