GAOTek SmartClass Fiber

This handheld SmartClass Fiber combines pass/fail fiber inspection and optical power measurement and comes with a 100 dB dynamic range that is perfectly suited for the measurement of low or very high power.



The GAOTek SmartClass Fiber combines pass/fail fiber inspection and optical power measurement (OPM) into one solution. With a 100 dB dynamic range, these 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 they perfectly fit applications where low power or very high power needs to be measured. In addition to providing a full day of battery-operated field use, the GAOTek SmartClass Fiber also functions well for fixed installations in central offices, production environments, and laboratory workbenches because they can operate via mains or be remotely controlled via USB 2.0 and Ethernet.

Additional Information

GAOTek SmartClassFiber OLP include:

  • SmartClass Fiber instrument
  • SC2 soft shoulder case, for SmartClass Fiber
  • Electronic tool kit with manual, data sheet, and reporting software on USB stick
  • UPP 2.5 mm universal optical adapter
  • Quick start manual and safety instructions
  • Alkaline batteries (8x)

By using the GAOTek SmartClass Fiber OLP the users can check fiber end-face quality and get pass/fail acceptance results with one button push. It features an integrated patch-cord microscope (PCM) for added value and improved workflow efficiency.

Combining the optical light source and optical power meters provides the greatest functionality, and automated tests avoid handling errors and speed testing. Automatic functions, such as Auto-lambda and Multi-lambda test, enable users to receive information about the emitted wavelengths, automatically set wavelengths on the compatible power meter, and accurately measure up to four wavelengths simultaneously. Users can also easily save test results (power, loss, fiber inspection) with real-time stamp to generate comprehensive certification reports.

The GAOTek SmartClass Fiber OLP inspection-ready optical power meters can be used anywhere. Technicians get ultimate flexibility and performance from this powerful easy-to-use solution that can help any technician become an instant fiber expert.
