The (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.
Mini Type Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading element can be adjusted to get any attenuation value in a range. This MVOA features low insertion loss, good resolution, integrating high stability, good reliability and applies for pre-emphasis attenuation, transmitter power control, in-line power equalization and amplifier power control, etc.
The Fiber Pigtailed Photodiode is a coaxially packaged photoelectrical component. It features high responsivity, low dark current and good temperature performance over a wide wavelength range. It can be applied for channel power monitoring in DWDM system, in-line optical network switching/protection monitoring (OLP), reconfigurable optical add/drop multiplexer (ROADM), and gain attenuation monitoring in EDFAs and networks's power detection, etc.
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.
