The Filter Wavelength Division Multiplexer is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelengths in a wide wavelength range. The FWDM offers very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.
The Polarization Maintaining Isolator is characterized with low insertion loss, high isolation, high return loss, high extinction ratio and excellent environmental stability and reliability. This optical isolator is ideal for polarization maintaining fiber amplifers, fiber lasers, high speed communication systems and instrumentation applications.
The Isolator Polarization Beam Combiner/Splitter is a compact device that provides both polarization beam combining and optical isolation in one integrated component. The most common application is to combine two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The Beam Combiner/Splitter has extremely low insertion loss, and it can improve the amplifier performance.
The 2 μm Polarization Maintaining Tap Coupler/Splitter is manufactured by using advanced technology to allow the input signal to be split at various ratios with high extinction ratio.
AFR Fiber Arrays are fabricated with high precision V-Groove substrate to achieve an excellent accuracy of fiber core position and high quality of polish surface. AFR provides high quality Fiber Array to meet customers' various demands with low insertion loss, high return loss and compact dimension.
