标准摘要
[中文适用范围]: 本标准提供了与光纤通信子系统、光发射机或用于通信子系统运行或测试的其他光源相关联的光谱的若干波长和谱宽特性的定义和测量程序。本文件还提供了边模抑制比和信号与源自发辐射比的定义和测量程序。测量是为了系统构建和/或维护的目的。在通信子系统信号的情况下,光发射机通常处于调制状态。 [外文原描述]: IEC 61280-1-3:2021 provides definitions and measurement procedures for several wavelength and spectral width properties of an optical spectrum associated with a fibre optic communication subsystem, an optical transmitter, or other light sources used in the operation or test of communication subsystems. This document also provides definitions and measurement procedures for side-mode suppression ratio and signal-to-source spontaneous emission ratio. The measurement is done for the purpose of system construction and/or maintenance. In the case of communication subsystem signals, the optical transmitter is typically under modulation. NOTE Different properties can be appropriate to different spectral types, such as continuous spectra characteristics of light-emitting diodes (LEDs), as well as multilongitudinal-mode (MLM), multitransverse-mode (MTM) and single-longitudinal mode (SLM) spectra, which are characteristic of laser diodes (LDs). This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of measurement of signal-to-source spontaneous emission ratio in 8.9; - change of document title to reflect the additional measurement; - additional information on the resolution bandwidth used in the measurement of the side-mode suppression ratio in 8.8; - use of a calibrated optical wavelength meter for accurate wavelength measurements of single-longitudinal mode lasers.
