FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The laser modules covered by this International Standard are purchased by system suppliers
(SS) to be inserted in equipment which in turn are supplied/sold to a system operator (SO) or
a network operator (see definitions in Clause 3).
For the system operator to act as an informed buyer, knowledge of the potential risks posed
by the use of critical components is required.
Optoelectronic component technology is continuing to develop. Consequently, during product
development phases, many failure mechanisms in laser modules have been identified. These
failure mechanisms, if undetected, could result in very short laser lifetime in system use.

4 Laser reliability and quality assurance procedure
4.1 Demonstration of product quality
This standard (where required by the specification) gives the minimum mandatory
requirements and is part of a total laser reliability and quality assurance procedure adopted
by the laser module manufacture.
It also gives guidance on the activities of the system supplier, and the system operator as well
as feedback of field performance, the laser module manufacturer and the system supplier.
The laser module manufacturer shall be able to demonstrate, by means of qualification
approval of devices, technology approval or capability approval of the manufacturing process:
a) a documented and audited manufacturing process including the qualification of purchased
components in accordance with ISO 9001;
b) a performance qualification programme, including for example, accelerated life testing,
burn-in and screening of components and modules;
c) a qualification maintenance programme to ensure continuity of reliability performance;
d) a procedure to feedback reliability issues to development and production.
4.2 Testing responsibilities
4.2.1 General
The testing detailed in Tables 1 and 2 is to be performed by the laser module manufacturer
and component suppliers (where applicable). Additional testing may be specified in the
specification.
4.2.2 Recommendation applicable to laser customer/system supplier
The system supplier is recommended to have a programme to analyse and verify the results
including failure analysis. This programme includes an independent life test of fully packaged
laser modules, see Table 2, Test 1 and/or Test 2 and 3 and/or Test 5 (sample size >10 per
test).
4.2.3 Recommendation applicable to system operator
The system operator is recommended to have a programme to monitor and report field failure
rates in sufficient detail to enable system supplier and laser module manufacturer to initiate
any necessary corrective actions at an early stage in the lifetime of a product.
Suppliers may have different approaches (i.e. to reliability concepts) during the development
of product maturity and resource limitations may dictate testing strategies.
Alternative tests and activities to those specified are permitted provided the LMM/SS/SO can
show intent to remove end-product failures and the associated failure mechanisms. However,
this will require significant data to substantiate compliance.
4.3 Quality improvement programmes (QIPs)
Quality improvement programmes (QIPs) shall be initiated with component suppliers and
customers (SOs, SSs and LMMs) to address non-compliances (including quality and reliability
problems identified during subsequent service life of the laser). The correction of non-
compliances and subsequent QIPs are a required strategy to minimize reliability risks. The
operation of QIPs should be stated in the quality approval (QA) generic and capability
approval documents.

5 Tests
5.1 General
The tests described in Tables 1 and 2 are designed to accelerate the main failure
mechanisms known to be reliability hazards in laser modules (see IEC/TR 62752-2:2008).
Where appropriate, the CQC shall demonstrate an ability to reduce end product failure
mechanisms. Final product validation is required to demonstrate that CQCs are operating at
the boundaries of the process or technology. These tests will reduce the risk of unreliable
components entering system use and will enable estimates to be made of the distribution of
laser lifetimes and hence the laser failure rates.
The sample size and level of testing may vary depending on the business volume between the
laser customer/system supplier (SS) and laser module manufacturer (LMM). This information
will be given in the capability approval (CA) document and the specification where appropriate.
NOTE It is essential that the lasers evaluated are entirely representative of standard production devices, and
have passed all the production and/or specified (where applicable in the specification) burn-in and screening
procedures.
Table 1 – Initial qualification
These tests will normally be performed by the laser manufacturer as part of an initial
qualification programme.
Table 2 – Maintenance of qualification
These tests cover periodic monitoring performed on production devices to ensure that the
quality and reliability performance established during initial qualification is maintained or
improved.
5.2 Structural similarity
Where a range of laser modules is produced by a laser manufacturer, there may be some
significant structural similarity between different type codes. A combination of results from
different test programmes, where appropriate, is therefore permitted.
Consideration should be given to the fact that minor differences in technology or processing
can have a major impact on reliability, whilst not being apparent during quality assessment.
Evidence shall be presented which demonstrates that all results are directly relevant.
5.3 Burn-in and screening (when applicable in the specification)
NOTE See IEC/TR 62572-2:2008.
The screening test should be designed by the laser module manufacturer specifically for his
particular technology. Any approach based on similarity to that which is performed by other
manufacturers, is good for comparison purposes, but can be ineffective in achieving the
actual screening goal. This is particularly true for fibre optic components whose technology is
not yet mature and varies significantly from supplier to supplier.
Where a manufacturer can demonstrate component and process stability, screening pro-
cedures may be revised.
