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 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. The optical circulator provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
The Faraday Mirror is a passive device that provides 90 degree rotation regarding the polarization state of the input light. The FM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in EDFAs, fiber lasers and fiber instruments to minimize the polarization effect.
The Polarization Beam Combiner/Splitter is a compact high performance lightwave component that combines two orthogonal polarization signals into one output fiber. The most common application is to combine two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. This Beam Combiner/ Splitter can also be used as a beam splitter.
The High Power (18+1)×1 Pump & Signal Combiner enables highly efficient combining of the powers from up to 18 multimode pump diodes and a signal laser into a double cladding output fiber.The pump and signal combiner can handle more than 1 kW combined power. Available for different fiber types.
