The 2 × 2 Polarization Maintaining Optical Circulator is a compact, high performance 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. This optical circulator provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
The Multimode Polarization Insensitive Isolator is designed and manufactured according to Telcordia standard. The unique manufacturing process and optical path epoxy-free design enhance the device achieve high power handling capability. The device is characterized with high performance, high reliability and low cost. The optical isolator has been widely used in fiber lasers, transmitters and other fiber optics communication equipment to suppress back reflection and back scattering.
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.
AFR's MEMS Variable Optical Attenuator is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS Variable Optical Attenuator chip consists of a tilting mirror to change light coupling between input and output fibers. The components are characterized with low insertion loss, fast response and compact size. The MEMS Variable Optical Attenuator is widely uesd in WDM networks, power control or gain variation in EDFA.
The Polarization Maintaining Filter Coupler is manufactured using advanced technology to allow the input signal to be split at various ratios with high extinction ratio. The PM Filter Coupler/Splitter supports both polarizations.
