DESCRIPTION
BS EN 61280-2-9:2009
This standard BS EN 61280-2-9:2009 Fibre optic communication subsystem test procedures is classified in these ICS categories:
- 33.180.20 Fibre optic interconnecting devices
- a diffraction-grating-based OSA,
- a Michelson interferometer-based OSA,
- and a Fabry-Perot-based OSA.
This second addition cancels and replaces the first edition published in 2002 and constitutes a technical revision. The main changes from the previous edition are as follows:
- A paragraph has been added to the Scope describing the limitations due to signal spectral width and wavelength filtering;
- and Annex B has been added to further explain error in measuring noise level due to signal spectral width and wavelength filtering.
