FABRY-PEROT ITU REFERENCE
*Patents pending

• Reference notches at ITU grid
  
• Superior accuracy
  
• Athermal optics ensure excellent thermal stability
  
• Hermetic sealing for high reliability
  
• Reflection mode operation

The Fibera Fabry-Perot ITU Reference (FPIR) series is a compact, high accuracy Fabry-Perot reflection filter based on a newly patented, proprietary technology. These devices establish a series of periodic notches with spacing of 100, 50 and 25 GHz deviating from ITU grid less than 1.25 GHz over temperature, wavelengths and aging.

The Fibera FPIR is hermetically sealed and is insensitive to environmental temperature variations. Hermetic sealing not only ensures the accuracy of laser wavelength, but also the reliability of the device.

The Fibera FPIR is ideal for DWDM channel monitoring, optical spectrum analyzer/wavelength meter calibration, and tunable filter ITU channel setting applications. Custom tuning option is available.
