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 2 μm Polarization Insensitive Isolator is designed and manufactured according to Telcordia standard. The unique manufacturing process and optical path epoxy-free design enhance the device's high power handling capability. This optical isolator is characterized with high performance and reliability. It is designed specially for 2 μm laser system.
The Singlemode Dual Window Wavelength Flattened 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 of both 1310 nm and 1550 nm windows. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
The Special Wavelength Coupler offers very low insertion loss, low polarization dependent loss and excellent environmental stability. Accurate coupling ratios from 0.01/99.99 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 PM FWDM series provides wavelength division multiplexing while maintaining signal polarization. This component is based on environmentally stable thin film filter technology and is characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.
