IEC/TR 62572-2:2008(E) provides guidance on:
- the testing that a system supplier should ensure is in a place prior to procurement of a laser module from a laser module manufacturer;
- a range of activities expected of a system supplier to verify a laser module manufacturer\'s reliability claims.
This technical report deals with reliability assessment of laser modules used for telecommunication guidance on testing, use of failure criteria and reliability predictions is provided.
