IPC D-640

Abstract

Scope: This document provides design and critical process requirements and technical insight for cable and wire harness assemblies incorporating optical fiber, optical cable and hybrid wiring technology. Reference materials listed in this text are among those considered as required reading. The User is encouraged to obtain all relevant referenced materials, as this document cannot (nor can any single document) cover every material, process, environment, performance or safety aspect that affect a given design. Purpose This standard is intended to provide information on the general design requirements for optical fiber, optical cable, hybrid wiring harness assemblies and fiber optic communications systems (FOCS) to the extent that they can be applied to the broad spectrum of optical cable and wiring harness design. This document is intended for use by the design engineer, manufacturing engineer, quality engineer or other individual responsible for the tailoring of specific requirements of this document to the applicable performance class. It is not the intent of this document to exclude any alternate or contractor-proprietary documents or processes that meet or exceed the baseline requirements established by this document. Use of alternate or contractor-proprietary documents or processes shall [A1A2A3] require review and prior approval of the User. For purposes of this document: a) The Designer is the design agent for the User. b) The User is the individual, organization, company, contractually designated authority or agency responsible for the procurement or design of electrical/electronic/electromechanical (EEE) hardware, and having the authority to define the class of equipment and any variation or restrictions to the requirements of this document (i.e., the originator/custodian of the contract detailing these requirements). The User is considered the Design Authority. c) The Supplier is considered the individual, organization or company which provides the Manufacturer (assembler) with components (e.g., electrical, electronic, electromechanical, mechanical, printed boards, etc.) and/or materials (e.g., solder, flux, cleaning agents, etc.). d) The Manufacturer is considered the entity that provides a service or product to the User.
