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.
AFR's LaseGuard Isolator Series is designed for guarding the laser from back reflected light. The isolator normally rotates the polarized plane 45° clockwise in the forward direcition, an λ/2 waveplate is an option if other output polarization is preferred. The high transmission efficiency, high isolation, high power handling ability and large aperture features make it flexible to fit different applications in laser protection.
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.
The Polarization Maintaining Faraday Mirror is a passive device that provides 90 degree rotation regarding the polarization state of the input light. The PMFM 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 1064 nm Isolator Polarization Beam Combiner/Splitter is a compact device which provides both polarization beam combining and optical isolation functions in one integrated device. The most common application is to combine the light of two pump lasers into a single fiber by doubling the pump power.
