The Multimode Filter Wavelength Division Multiplexer series is based on environmentally stable thin film filter technology. These components combine or separate light at different wavelengths in a wide wavelength range. They offer very low insertion loss, 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 multi-mode fiber communication, CATV and testing instrumentation.
The Polarization Maintaining Tap Coupler/Splitter is manufactured using advanced technology to allow the input signal to be split at various ratios with high extinction ratio.
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 isolator into a single compact package. It has high extinction ratio and very low insertion loss. This optical isolator is ideal for fiber amplifiers and fiber optic systems where signal monitoring is required.
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.
