PowerChek is an innovative new optical power meter that equips fiber technicians with the ability to complete jobs faster, correctly, and on time – the first time. This compact instrument not only measures optical power, but also provides additional benefits that allow users to ensure safe measurements, document results, generate reports, and integrate with other devices to enable numerous additional capabilities.


  • Eliminate the test lead when measuring optical power
  • PowerChek connects directly with the bulkhead being tested by utilizing PowerChek connectors that attach to the device.
  • Always ensure a safe test
    By contacting the ferrule, instead of the fiber, the PowerChek will not damage the link under test.
  • Easily access your connections in any location
    Adjustable arm optimizes access to connector ports in densely populated and difficult to reach locations.
  • Pair with your mobile device over Bluetooth 
    Use with FiberChekMOBILE app to measure & store readings in real-time, generate reports, and share results via email, etc.
