The PMDWDM series is designed and manufactured according to Telcordia and ITU standard, and it preserves the polarization of optical signals. This device use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, excellent environmental stability and high extinction ratio. They can be used individually to perform single channel add or drop function or can be used in DWDM systems and fiber sensor systems, etc.
The 2 μm In-Line Polarizer is designed to pass light with one specific polarization while blocking the other polarization. It can be used to convert unpolarized light into polarized light with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties. It is ideal for high speed communication systems and test instrumentations where high polarization extinction ratio is required.
AFR’s High Power Fiber to Free-Space Isolator (HPFSI) is the best choice for high power industrial pulse fiber lasers. With unique, patented technology, the power handling capacity was elevated to 500 W average laser power, and with very competitive cost-effectiveness.
The Backward pump (6+1)×1 High Power Combiner with ClearCut Fiber Bragg Grating enables highly efficient combining of the powers from up to 6 multimode pump diodes into an FBG with low insertion loss for high power fiber lasers. With AFR's ClearCut design and packaging, the devices can handle 3 kW pump power and 3 kW signal power.
The Polarization Maintaining Filter Wavelength Division Multiplexer provides wavelength division multiplexing (or demultiplexing) while maintaining signal polarization. The components are based on environmentally stable thin-film filter technology and are characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.
