Fibre optic communication subsystem test procedures - Part 1-3: General communication subsystems - Measurement of central wavelength, spectral width and additional spectral characteristics
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.
IEC 61280-1-3:2021 is part of the IEC 61280 series of fibre optic communication subsystem test procedures. This international standard defines terms and measurement procedures for central wavelength, spectral width and other spectral characteristics of optical spectra used in fibre optic communication subsystems. It covers measurements for transmitters and light sources used during system construction and maintenance, typically with the optical transmitter under modulation.
Key additions in the 2021 (3rd) edition include:
