F-tone Networks Optronics’Singlemode wavelength division multiplexer WDM 1310/1550 1X2 2X2 combine or separate light at different wavelengths. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. These components have been extensively used in CATV, WDM networks, Fiber sensor and fiber optics instrumentation.

the In-line Polarizer is designed to pass the light with the specified polarization,blocking the others.the function is tranform non-polarized light into linearly polarized light, for the high extincton ratio.It is also used to enhance the extinction ratio of the signals of precision measurement system, fiber sensor, high speed test instrumentations where the high extinction ratio prosper is required.

the Polarization Beam Combiner & Splitter is a device with compact size , which combines two orthogonal polarization signals into one output fiber. PBC/PBS is commonly applied to combining the reflected light of fiber laser with fixed phase difference to one fiber ,to receive the interferometric fringe in Fiber Optics Current Transducer(Foct), Gyro, Raman Amplifier,with high extinction ratio. PBC/PBS can also be used as a PM splitter.

The Bandpass Filter is a micro optics device based on environmentally stable thin film filter technology. It is widely applied to blocking  the unwanted noise signals in EDFA and fiber pump laser systems, to get the signals needed. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.×ðÁúÈËÉú¾ÍÊDz©×¨ÒµÑб¬·¢²ú1064nm PM fiber Band Pass Filter, 1μm fiber laser,¹¤Òµ¼¶1064nm PM fiber Band Pass Filter, 1μm fiber laser,ÊÇÒ»¸öרҵµÄ1064nm PM fiber Band Pass Filter, 1μm fiber laser³§¼Ò,ÓкܺõÄ1064nm PM fiber Band Pass Filter, 1μm fiber laser¼Û¸ñ¡£×ðÁúÈËÉú¾ÍÊDz©×¨ÒµÑб¬·¢²úµÄ1064nm PM fiber Band Pass Filter, 1μm fiber laser¹ã·ºÓ¦ÓÃÓÚº½Ìì¡¢º½¿Õ¡¢µçÁ¦¡¢Ìú·¡¢Ò½ÁÆ¡¢½»Í¨¡¢Í¨ÐÅ¡¢µÈ¸÷´óÁìÓò¡£

the Polarization Maintaining Optical Circulator (fast axis blocked) is a compact lightwave component  that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3 and incoming Port 3 signals to Port 4, while blocking the reflected light. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
