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 the output fiber does not couple into the detector. The hermetically sealed InGaAs photo detector has a low dark current and a flat and rapid power response across a wide wavelength range.
