BS EN 4533-002:2017审查了从一开始就能够准确测量光纤链路的要求 在系统从安装到使用的整个生命周期内。第2部分将解释 与光链路测量相关的问题，并提供解决这些问题的技术。这 该文件讨论了与被动层相关的关键参数的测量 （即光通过光学线束的传输）。它没有讨论系统测试，例如误码率。交叉引用:EN 4533-004EN 4533-001EN 4533-003EN 2591-601购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 4533-002:2017 examines the requirements to enable accurate measurement of fibre optic links from start of life and during the life cycle of the system from installation and through-service. Part 2 will explain the issues associated with optical link measurement and provide techniques to address these issues. This document discusses the measurement of key parameters associated with the passive layer (i.e. transmission of light through an optical harness). It does not discuss systems tests e.g. bit error rates.Cross References:EN 4533-004EN 4533-001EN 4533-003EN 2591-601All current amendments available at time of purchase are included with the purchase of this document.
