The TIWDM series combines filter WDM, tap coupler and isolator into a compact package. This device is ideal for fiber amplifier application to provide input signal power monitoring, pump/signal multiplexing and isolation functions at the same time. It offers the advantages of cost saving, space saving, and performance improvement.
The multi-channel Dense Wavelength Division Multiplexer Module is based on thin film DWDM devices by cascading individual channels into sequence. Channel numbers can be as high as 40 (16) for 100 (200) GHz systems in C band or in L band. They are featured with wide passband, low insertion loss, high channel isolation and high environmental stability. They can be used in dense WDM systems to perform mutiplexing or demutiplexing functions.
The Singlemode Broadband Coupler offers very low insertion loss, low polarization dependent loss and excellent environmental stability. This coupler series offers accurate coupling ratios from 1/99 to 50/50 and is available with very good uniformity in a wide wavelength range. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
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 2 μm Fused Wavelength Division Multiplexer combines or separates light at 1570 nm (800 nm) and 2000 nm windows. They offer very low insertion loss and excellent environmental stability.
