  • Does Fibre Channel not require cable inspection

    Does Fibre Channel not require cable inspection

    Inspections of fiber optic cable plant installation are not generally required, and practically nobody ever does one on a new fiber optic network. IEC 60794 is the international standard series governing the design, construction, and performance verification of fibre optic cables. As a result, some cables are not installed “in a neat and workmanlike manner” as described by the ANSI/NECA/FOA 301 installation standard for fiber. It is measured by the optical fiber (and cable) manufacturer but can also be field-tested and verified. However, individual fiber attenuation is not a requirement for evaluating overall system performance because it is implicitly included in any “end-to-end” insertion loss measurement that is. FOA continues to provide practical, one-page standards for insertion loss, OTDR testing, optical power measurement, and connector inspection. Using outdated methods can lead to compliance issues and costly rework.
