VIAVI OLP-85 Optical Fiber Power Meter

The SmartClass Fiber OLP-85 and -85P combine pass/fail fiber inspection and optical power measurement (OPM) into one solution. With a 100 dB dynamic range, the OLP-85 and -85P handheld optical power meters are professional, versatile, and compact instruments perfect for any fiber-optic network power or loss test applications. Their high accuracy over the entire range means that the OLP-85 and -85P perfectly fit applications where low power or very high power needs to be measured.


  • Battery-operated field-portable optical power meters with an 800 to 1700 nm measurement wavelength range (1 nm incremental setting) and high accuracy over an ultra-wide 100 dB dynamic range
  • 2.5 mm and optional 1.25 mm universal push-pull (UPP) adapter system compatible with all optical connector types
  • 3.5-in color touch screen with integrated stylus
  • Individual threshold settings for power and loss pass/fail analysis
  • Onboard fiber inspection and test results storage with time stamp
  • Data transfer and remote control via USB or Ethernet interface
  • Auto-lambda and multi-lambda test functions in combination with VIAVI light sources
