光放大器.第6部分:分布式拉曼放大器

[中文适用范围]： 本部分IEC 61292是一份技术报告，涉及分布式拉曼放大（DRA）。其主要目的是为未来与DRA相关的标准（如规范、测试方法和操作程序）提供背景材料。本文档涵盖以下方面： - 拉曼放大的一般概述； - DRA的应用； - 与DRA相关的性能特征和测试方法； - 与DRA部署相关的操作问题。 由于DRA是一项相对较新且仍在快速发展的技术，本文档中的一些材料可能在相当短的时间内变得过时或不相关。本文档将频繁更新以尽量减少这种可能性。 [外文原描述]： IEC TR 61292-6:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 61292-6:2023 which is a Technical Report, relates to distributed Raman amplification (DRA). Its main purpose is to provide background material for future standards related to DRA, such as specifications, test methods and operating procedures. This document covers the following aspects: - general overview of Raman amplification; - applications of DRA; - performance characteristics and test methods related to DRA; - operational issues relating to the deployment of DRA. As DRA is a relatively new technology, and still rapidly evolving, some of the material in this document can become obsolete or irrelevant in a fairly short period of time. This document will be updated frequently to minimize this possibility. This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - correction of the formula for noise figure; - correction of errors in Figure 10.
