Product Description

FiberOWL 4 Bolt Quad Fibre Light Source & Power Meter

For Testing and Certifying Fibre Optic Networks

With many fibre optic network bids and Requests For Quote (RFQ) citing cable standards to specific guidelines, it is important for the network installer to ensure the network installation adheres to these requirements. The FiberOWL 4 Bolt Quad is a fibre light source & power meter that is supplied as a test kit that contains all the tools necessary to certify fibre optic links against popular cabling standards laid out for both Multi Mode and Single Mode fibre optic networks.

The FiberOWL 4 Bolt is an optical power meter that is Multi Mode and Single Mode ready and capable of certifying fibre links at 850nm, 1300nm, 1310nm and 1550nm wavelengths. It features a user-friendly Fibre Link Wizard that performs link budget calculation including integrated fibre link length testing, and sets a reference value using the characteristics of the link. The reference is the PASS / FAIL threshold and is calculated against the chosen standard. Up to 1000 fibre runs may be stored and then downloaded to a PC for report generation using the OWL Reporter software. It also features intelligent automated testing functions, such as automatic dual-wavelength storage and auto-wavelength recognition, which help reduce testing time and human error.

The second part of the test kit is the OWL WaveSource Quad a fibre optic light source that contains all four popular industry-standard wavelengths for testing and certification of Multi Mode (850nm & 1300nm) and Single Mode (1310nm & 1550nm) networks. Its quad wavelength outputs are all temperature stabilised for accurate measurements. The OWL WaveSource Quad has a built-in auto-wavelength switching protocol designed to synchronise the wavelength of the FiberOWL 4 BOLT fibre optic cable tester. There are three connector options available ST, SC and FC.


  • Certification of Single Mode fibre links at 1310nm and 1550nm and Multi Mode fibre links at 850nm and 1300nm.
  • Auto-wavelength recognition and automatic data storage reduce testing time and human error.
  • Integrated fibre optic length tester for accurate link length measurements.
  • Data storage for up to 1000 data points including run labels, fibre type, and link information including link name, date, reference power values, fibre 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 fibre certification reports.
  • Absolute or relative mode for giving you instant pass/fail results.
  • Selectively view, delete or resample data points.
