Tap PD Power Monitor
Tap Photo Detector (Tap PD) is a hybrid device that integrates a thin-film tap collimator with a high sensitivity PIN photodiode. This product adopt a new design solution that offers very high responsibility, low dark current, compact size with wide band-width, high reliability and low cost. It can be used in a variety of application, such as DWDM channel monitoring, Optical line protection monitoring, ROADM Multiplexers, Gain monitoring in Amplifier. Customized design is available from vfibre.
Application
WDM Channel monitoring
EDFA Power monitoring
ROADM Module power monitoring
