The Singlemode Broadband Coupler offers very low insertion loss, low polarization dependent loss and excellent environmental stability. This coupler series offers accurate coupling ratios from 1/99 to 50/50 and is available with very good uniformity in a wide wavelength range. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
The Coarse Wavelength Division Multiplexer series is designed and manufactured based on Telcordia standard. The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in CWDM systems.
The 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.
The ClearCut kW Package-Free Fiber Bragg Grating products are ultra low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut design and special process, the FBG can handle kilowatt level pump power and signal power with recoated only.
