标准摘要
[中文适用范围]： IEC 61280 的本部分旨在描述一种测试程序，以验证是否符合预定的波形模板，并测量眼图和波形参数，如上升时间、下降时间、调制幅度和消光比。 [外文原描述]： IEC 61280-2-2:2012 describes a test procedure to verify compliance with a predetermined waveform mask and to measure the eye pattern and waveform parameters such as rise time, fall time, modulation amplitude and extinction ratio. This fourth edition cancels and replaces the third edition published in 2008 and constitutes a technical revision .This edition includes the following significant technical changes with respect to the previous edition: additional definitions; clarification of test procedures. Keywords: optical eye pattern, waveform, modulation amplitude, extinction ratio The contents of the corrigendum of February 2015 have been included in this copy.
