Fibre optic communication subsystem test procedures - Part 2-2: Digital systems - Optical eye pattern, waveform and extinction ratio measurement
01-06-2011
14-08-2008
This part of IEC 61280 is to describe a test procedure to measure the eye pattern and waveform parameters such as rise time, fall time, overshoot, and extinction ratio. Alternatively, the waveform may be tested for compliance with a predetermined waveform mask. This edition includes the following significant technical changes with respect to the previous edition: - the necessity of DC coupling for extinction ratio measurement is clarified; - the definition of extinction ratio has been revised to better harmonize with ITU-T; and - the definition of OMA has been clarified.
