This is your "QuickStart" guide to testing fiber optic cable plants, patchcords and communications equipment with a fiber optic light source and power meter. Fiber optic testing of a newly installed system not only verifies that the system meets its design requirements, but also creates a performance baseline for all future testing and troubleshooting of t at system. It defines a minimum leve e fiber optic cabling extends between buildings. Although the standard covers premises installations, many of the provisions included here ar SI/ NFPA 70, the National Electrical Code (NEC). References to FOA "1. n TIA-568-C. 0, but this does not mean it is not important. The OTDR trace can be used for cable acceptance, splice and connector loss, docu-mentation, troubleshooting, fault location, o tical return loss and to measure the length of the system. The OTDR ful tool is does not replace the need for. Reliable cabling is the foundation of a strong network, and proper fiber optic testing is your first line of defense against costly outages. As a nationwide provider of managed network services, TailWind performs fiber testing across hundreds of sites to help multi-location businesses stay. The Optical Time Domain Reflectometer (OTDR) will be used to test splice loss and to conduct span analysis. An Optical Power Meter and Laser Light Source will be used to measure power loss on each completed ring or distribution span to verify continuity between fibers (no fibers incorrectly spliced.
