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 Integrated Tap Photodiode (TAPD) integrates the functionality of an optical coupler and a photodiode for optical network's power detection. It applies for channel power monitoring in DWDM system, in-line optical network switching protection monitoring (OLP), reconfigurable optical add/drop multiplexers (ROADM), and gain/attenuation monitoring in EDFAs and networks's power detection, etc.
The Multimode Patchcord series has excellent environmental stability, high return loss and low insertion loss. It is ideal for multimode fiber lasers and test instrumentation applications.
