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

The collimator is the base device of optics fiber passive component. the collimator is designed for long working distance and large spot of opticdal beam, The collimator has the advantage of low insertion loss, High return loss, High power handing long working distance and large spot of optical beam......

the PM Manual Variable Optical Attenuator is designed and manufactured to reduce the output optical power, get the power suitable. It is with low insertion loss, high extinction ration, high return loss and low Adjustment Precision,The PM Attenuator is widely apllied at fiber laser ,fier CWDM/DWDM/OADM communication system.

 single channel Coarse WDM is based on a patented athermal platform for optical devices. This multiplexer features ultra low insertion loss, superb thermal stability, and unparalleled reliability. The technology is a lead-free packaging platform and contains no epoxies in the optical path. Green CWDM is Telcordia GR-1221 and GR-1209 tested, qualified for uncontrolled environment applications, and is in compliance with industry green initiatives such as Rohs and WEEE.
