Bristol 828 High-speed Optical Wavelength Meter

The fastest wavelength meter for optical transceiver testing

Bristol Instruments

The 828 Series High-Speed Optical Wavelength Meter uses interferometer technology that is very different than that employed by other wavelength meters used for optical transceiver testing applications. A Fizeau etalon design is used to generate a spatial interferogram that is detected by a fast InGaAs photodetector array. Using an on-board digital signal processor, the interferometric data is processed quickly into an accurate wavelength measurement. The combination of these technologies provides an unmatched, sustained measurement rate of 1 kHz.


  • Wavelength measured to an accuracy of ± 3pm
  • Fatest measurement rate of 1kHz for reduced testing times
  • Automatic calibration with a built-in wavelength standard
  • Measurement confidence level of >99.7%
  • Traceable to NIST standards
  • Simultaneous optical power measurement to ± 0.5dB
  • Convenient touch-screen display reports measurement data in a variety of formats
  • Interfacing via SCPI using USB, Ethermet or GPIB
  • Data streaming available using RS-422 serial interface
  • Internal data storage for up to one million measurements
  • Rugged design for manufacturing environments
  • Includes 5 year warranty
