Many fiber optic network bids and Requests For Quote (RFQ) are citing cabling standards to specify the set of guidelines (such as fiber length) that the network installer must follow during the network installation. Adherence to such standards is meant to ensure the quality of the installation and guarantee that the network will perform as it was designed. The process of testing a network installation to ensure its adherence to specified standards is called certification, and often requires hardcopy documentation as proof of adherence to standards. The Micro OWL 2 / Dual OWL 850 Test Kit contains the tools necessary for certifying multimode fiber optic links against a myriad of cabling standards at 850nm. The Micro OWL 2 optical power meter is multimode and singlemode ready, and contains a user-friendly Fiber Link Wizard that performs link budget calculation, 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, and downloaded to a PC for report generation using our OWL Reporter software. Its universal port allows connections to ST, SC, and FC, and also includes a 1.25mm universal port for connection to LC, MU, and other SFF connectors. The Dual OWL 850 is our NIST traceable multimode light source. Its 850nm output is temperature-stabilized for accurate measurements.
