Features:

  Low Ripple
  Low Insertion Loss
  Excellent Directivity Performance
  Epoxy-Free Optical Pat
  Extremely Low Dark Current

Description:

Go!Foton’s integrated Tap Detector(TAPD) series combines an optical coupler, based on our 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.

Qualification & Reliability: 

Opto-Electronic devices has been qualified according to Telcordia GR-468, CORE “Generic Reliability Assurance Requirements for Opto-Electronic Devices used in Telecommunications Equipment” and the applicable company Product Quality and Reliability Program that includes conduct of Telcordia GR-468 section 2.1.4 Requalification and On-going Reliability Test (ORT) requirements and/or its equivalent. Any change to identified test conditions requires justification and approval and shall be communicated to Customers.
