(1.3 to 2.5mm)

The Tap Optical Power Monitor is a hybrid fiber optical passive component that integrates a thin-film tap of flat spectral response with a high sensitivity PIN photodiode for power monitoring applications. The Power Monitor minimizes component assembly costs and module footprint while increasing module design efficiency by facilitating fiber Management. The Power Monitor combines the functionality of an optical coupler and a photodiode while delivering low insertion loss and low dark current with high-temperature stability over a wide wavelength range. Our directional version works well from 1260nm to 1620nm band.

Notes:

  1. Insertion Loss excluding connectors
  2. The net responsivity is defined as the ratio of the PD current output and optical power measured at output fiber
  3. Single Mode Fiber version only
  4. PM Fiber version only
  5. Directivity defines the responsivity contrast between the case that light power comes from input fiber port and the case that light power comes from output fiber port. From 1260 to 1620nm
