1 Scope

This International Standard deals with reliability assessment of laser modules used for telecommunication.

The aim of this standard is:

• to establish a standard method of assessing the reliability of laser modules in order to minimize risks and to promote product development and reliability;

• to establish means by which the distribution of failures with time can be determined. This should enable the determination of equipment failure rates for specified end of life criteria.

In addition, guidance is given 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.

Further details concerning the rationale are given in Annex A and Annex B.
