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.
The Backward pump (6+1)×1 High Power Combiner with ClearCut Fiber Bragg Grating enables highly efficient combining of the powers from up to 6 multimode pump diodes into an FBG with low insertion loss for high power fiber lasers. With AFR's ClearCut design and packaging, the devices can handle 3 kW pump power and 3 kW signal power.
The Polarization Maintaining Faraday Mirror is a passive device that provides 90 degree rotation regarding the polarization state of the input light. The PMFM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in amplifiers, fiber lasers and fiber instruments to minimize the polarization effect.
The Multimode Pump Protector is a micro optic device based on environmentally stable thin-film filter technology. It is used to block out unwanted noise signals in multimode fiber communication systems. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
