This guide covers what you need to know about IPC-A-640: the class system, key acceptance criteria, inspection requirements, and how it relates to other IPC standards. This constraint eliminates the concern that the fiber will have high loss in the 1360 nm to 1460 nm band caused by OH. That's why IPC developed IPC-A-640, the acceptance standard specifically for optical fiber, optical cable, and hybrid wiring harness assemblies. These standards help you avoid legal trouble, reduce insurance risks, and keep your systems reliable. Follow. This document outlines the specifications for a single-mode optical fiber and cable designed for use around the 1310 nm zero-dispersion wavelength, suitable for both the 1310 nm and 1550 nm regions, and compatible with analogue and digital transmission.
