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 hard-copy documentation as proof of adherence to standards. The Fiber OWL 7 Dual OWL Test Kit contains the tools necessary for certifying fiber optic links against a myriad of popular cabling standards in multimode networks, commonly referred to in the industry as Tier 1 certification. The Fiber OWL 7 (p/n: F7X) optical power meter is multimode and single mode ready, and contains a user-friendly Fiber Link Wizard with color diagrams to guide the setup process, calculate the link budget, and set the optical reference. Up to 10,000 fiber runs may be stored in internal memory, and can be downloaded to a PC for report generation with OWLView software. The universal detector port on the F7X comes with 2 adapter caps, one for 2.5mm connectors such as SC, ST, and FC, and the other for 1.25mm connectors such as LC. The length testing port is SC. The Dual OWL Pro (p/n: DP83) fiber optic light source is designed for accurate testing and certification of multimode networks. The light source outputs are temperature-stabilized for accurate measurements.
