The Singlemode Coupler offers very low insertion loss and excellent environmental stability. Accurate coupling ratios from 1/99 to 50/50 are available with very good uniformity in the operating wavelength range. These components find extensive applications to perform power splitting and monitoring functions in all kinds of optical communication systems.
The 1064 nm Faraday Mirror is a passive device that provides 90 degree polarization rotation respect to incident light. The FM 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 Dense Wavelength Division Multiplexer series is designed and manufactured based on Telcordia standard and ITU standard.The devices use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.
A micro lens was formed at the end of fiber to couple with active chips in LD and PD modules. Conical and wedge lensed fiber are both available, other shapes can be customized. And AFR can provide one stop service for fiber tail assembly, including lensed fiber, fiber metallization, AR-coating, feedthrough soldering, fiber connectorization, etc.
The Dual Polarization Beam Combiner/Splitter, 2 × 2 PBC/PBS, is a compact high performance lightwave component that combines or divides two orthogonal polarization signals into one or two output fibers. The most common applications are in polarization mode dispersion compensator, EDFA, Raman Amplifier, coherent telecommunication systems and fiber sensor. The Dual Polarization Beam Combiner/Splitter is characterized with high extinction ratio and low insertion loss.
