The Polarization Maintaining Fused Coupler offers very low insertion loss, high polarization extinction ratio and excellent environmental stability. Accurate coupling ratios from 0.01/99.99 to 50/50 are available with very good uniformity at center wavelength. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
The ClearCut kW Package-Free Fiber Bragg Grating products are ultra low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut design and special process, the FBG can handle kilowatt level pump power and signal power with recoated only.
The High Power Polarization Insensitive Circulator is characterized with low insertion loss, high isolation, high power handling, high return loss. This circulator is ideal for fiber lasers and instrumentation applications.
The Integrated Tap Photodiode (TAPD) integrates the functionality of an optical coupler and a photodiode for optical network's power detection. It applies for channel power monitoring in DWDM system, in-line optical network switching protection monitoring (OLP), reconfigurable optical add/drop multiplexers (ROADM), and gain/attenuation monitoring in EDFAs and networks's power detection, etc.
The 2 μm Fused Wavelength Division Multiplexer combines or separates light at 1570 nm (800 nm) and 2000 nm windows. They offer very low insertion loss and excellent environmental stability.
