IEC 62343-2:2014 applies to dynamic modules and devices (DMs) which are commercially available. Examples are tuneable chromatic dispersion compensators, wavelength selective switches and optical channel monitors. Optical amplifiers are not included in this list, but are treated in IEC 61291-5-2. For reliability qualification purposes, some information about the internal components, parts and interconnections is needed; these internal parts are treated as black boxes. This standard gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes. The objectives of this standard are the following:
- to specify the requirements for the reliability qualification of DMs;
- to give the minimum list of reliability qualification tests, requirements on failure criteria during testing and on reliability predictions, and give the relevant normative references. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. The main change with respect to the previous edition is the addition of Annex A (informative), Reliability test items and their conditions. Keywords: dynamic modules and devices (DMs), tuneable chromatic dispersion compensators, wavelength selective switches, optical channel monitors
