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.
The PMFCM series is manufactured by using advanced technology to allow the input signal to be split into multiple channels at a given splitting ratio with high extinction ratio, low excess loss, good uniformity, low WDL and low TDL. It can be widely used in fiber sensors, amplifiers, various laser applications, etc.
The 2 μm In-Line Polarizer is designed to pass light with one specific polarization while blocking the other polarization. It can be used to convert unpolarized light into polarized light with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties. It is ideal for high speed communication systems and test instrumentations where high polarization extinction ratio is required.
The 2 μm 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 the light of two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The 2 μm Polarization Beam Combiner can also be used as a beam splitter.
