Integrated TAP Detector (TAPD)
UnidirectionalApplications:
EDFA Power Monitoring/Control
DWDM Channel MonitoringFeatures:
Low Insertion Loss

Excellent Directivity

Superior Thermal Stability

Low Wavelength Dependent Loss

Low Dark Current

Telcordia GR-468-CORE Compliant

Description:

Go!Foton’s integrated Tap Detector(TAPD) series combines an optical coupler, based on NSG’s filter-on-lens
technology, with Go!Foton’s proprietary PIN photodiode to create a single channel optical power monitor. The
Unidirectional TAPD is designed specifically for EDFA applications. With this design, the reflected light from theoutput fiber does not couple into the detector. The hermetically sealed InGaAs photo detector has a low darkcurrent and a flat and rapid power response across a wide wavelength range.
