The 2000 nm & 793 nm (2+1)×1 Multimode Pump & Signal Combiner enables highly efficient combining of the powers from 2 multimode pump diodes and a signal laser into a double cladding output fiber. The Pump & Signal Combiner is also available for different fiber types.
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.
The High Power ClearCut Fiber Bragg Grating products are low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut design and packaging, the FBG can handle kilowatt level pump power and signal power. Custom configurations are available.
AFR's Integrated Polarization Maintaining Tap Power Detector (PMTAPD) integrates the functionality of a optical coupler and a photodiode for optical network's power detection. It applys for channel power monitoring in DWDM system, in-line optical network switchingprotection monitoring(OLP), re-configurable optical add/drop multiplexer(OADM), and gain/attenuation monitoring in EDFA, etc.
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.
