Description:
Go!Foton’s Integrated Tap Detector Array combines optical couplers, based on NSG’s filter-on-lens technology, with Go!Foton’s proprietary PIN photodiodes to create a multi channel optical power monitor. The integrated design reduces the number of parts, minimizes fiber handling and results in a compact footprint, which simplifies assembly of amplifier and WDM monitoring devices. The hermetically sealed InGaAs photo detector has a low dark current, a flat and rapid power response and extremely high temperature stability across a wide wavelength range. This device is also available with “Ribbonized Fiber” option for easy connection.
