What are the standards for Class I optical cable splicing

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. The technical examples and product names included throughout (such as closure types, cable models, and tools) are used solely for educational and reference purposes — to illustrate real-world applications of universal procedures and best practices. If a situation arises that is not specifically. That's why IPC developed IPC-A-640, the acceptance standard specifically for optical fiber, optical cable, and hybrid wiring harness assemblies. Typical applications of these methods include aerial, buried, and underground splices.
