IPC-A-640, officially titled “Acceptance Requirements for Optical Fiber, Optical Cable, and Hybrid Wiring Harness Assemblies,” provides acceptance criteria for cable and wire harness assemblies that incorporate optical fiber technology. While most engineers are familiar with IPC-A-620 for copper wire harnesses, IPC-A-640 addresses the unique inspection and acceptance challenges that fiber. Developed by the Fiber Optic Cable Acceptability Task Group (7-31m) of the Product Assurance Committee (7-30) of IPC. Users of this publication are encouraged to participate in the development of future revisions. 9 QUALITY ASSURANCE REQUIREMENTS – TEST. ing the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. The IPC-A-640. This new standard is a companion to the IPC-D-640 on optical fiber, cable and wiring.
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. They explain how to avoid common mistakes, clarify test reference methods, and provide visual guides. As the components like fiber, connectors, splices, LED or laser sources, detectors and receivers are being developed, testing confirms their performance specifications and helps. IEC 60794 is the international standard series governing the design, construction, and performance verification of fibre optic cables. 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. We offer full-service OEM and ODM solutions for fiber optic cables, assemblies, and connectivity products — from design and prototyping to global production and logistics.
