The Fiber OWL 4 BOLT optical power meter is multimode, and contains a user-friendly Fiber Link Wizard that performs link budget calculation (including integrated fiber link length testing), and sets a reference value using the characteristics of the link. This reference is the PASS/FAIL threshold and is calculated against the chosen standard. Up to 1000 fiber runs may be stored, then downloaded to a PC for report generation using our OWL Reporter software. The Dual OWL 850 fiber optic light source is designed for accurate testing and certification of multimode networks at 850nm. Its output is temperature-stabilized for accurate measurements.


  • Dual OWL Series fiber optic light sources offer fiber optic professionals a cost effective option for high quality multimode fiber testing in a compact, handheld package. The temperature compensated outputs are calibrated to couple -20dBm of optical power into multimode fiber. The sources are simple to operate with an intuitive two-button interface controlling power and selecting the output wavelength. LED indicators highlight the selected source and verify that battery power is sufficient to maintain the calibrated output power. 
  • Certification of multimode fiber links at 850nm
  • Integrated fiber optic length tester for accurate link length measurements
  • Data storage for up to 1000 data points including run labels, fiber type, and link information including link name, date, reference power values, fiber length, and number of splices and interconnects
  • Built-in loss wizard for calculation of maximum allowable loss values (link budget)
  • USB interface for continuous data logging, report printing, or data downloading
  • OWL Reporter software for printing formatted fiber certification reports
  • Absolute or relative mode for giving you instant pass/fail results
