Fiber Optic Cable Rate Testing Standards
The IEC has published a new standard for the testing of fibre optic cabling. IEC 61280-4-5 provides test methods to measure the attenuation of installed multimode and single-mode optical fibre cabling plant as well as the determination of their polarity and length. 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. Corning recommends that all fiber optic systems be tested to a minimum set. cations, security, control and similar purposes. Although the standard covers premises installations, many of the provisions included here ar SI/ NFPA 70, the National Electrical Code (NEC). They explain how to avoid common mistakes, clarify test reference methods, and provide visual guides.
