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 Pump Protector is a micro optics device based on environmentally stable thin-film filter technology. It is used to block out unwanted noise signals in EDFAs and fiber laser systems. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
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 Optical Fiber Mirror is designed and manufactured according to Telcordia standard. It is characterized with low insertion loss, excellent environmental stability and reliability. It has been widely used in fiber optics communication equipment, fiber sensing to reflect light input backward through the fiber.
