The Polarization Maintaining Fused Wavelength Division Multiplexer combine or separate light at different wavelengths. They offer very low insertion loss, high extinction ratio, and excellent environmental stability. These components can be operated on both fast and slow axis.
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 (2+1)×1 Multimode Pump and Signal Combiner enables highly efficient combining of the powers from 2 multimode pump diodes and a signal beam from the signal fiber into a double clad output fiber. The Pump & Signal Combiner is also available for different fiber types.
The ClearCut 2 μm Series 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 high power laser around 2 μm. Custom configurations are available.
The RC Fiber Faraday Mirror is a passive device that provides 90 degree rotation without regarding to the polarization state of the input light. The RCFM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in compact optical amplifier, DWDM systems, sensors, compact optical circuits and other fiber optic communication equipment to minimize the polarization effect.
