AFR provides Hermetic Fiber Feedthrough by hermetically attaching gold plated metal ferrule to fiber cables base on different applications to guarantee excellent hermetic feedthrough performance. SM, MM, PM individual fiber or ribbon fiber available upon request. The hermetic feedthrough is commonly used in PLC module, LD packaging and integrated optics packaging for hermetic sealing purpose.
The Faraday Mirror is a passive device that provides 90 degree rotation regarding the polarization state of the input light. The FM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in EDFAs, fiber lasers and fiber instruments to minimize the polarization effect.
The PMDWDM series is designed and manufactured according to Telcordia and ITU standard, and it preserves the polarization of optical signals. This device use environmentally stable thin film filter and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, excellent environmental stability and high extinction ratio. They can be used individually to perform single channel add or drop function or can be used in DWDM systems and fiber sensor systems, etc.
The Ultra Low Ratio Tap Coupler splits a very small amount of light from a signal path to a tap port. Low tap ratios such as 0.1%, 0.01% or 0.001% enable the monitoring photodetector to operate without damage or saturation. It is suitable for very high optical power, its main application is in the monitoring of optical sources such as fiber lasers.
The Polarization Maintaining Tap Isolator combines a tap coupler and polarization sensitive/insensitive isolator into a single compact package. It has high extinction ratio and very low insertion loss. This component is ideal for fiber amplifier and fiber optic systems where signal monitoring is required.
