IEC 62149 1 Edition 2 0 2011 12 INTERNATIONAL STANDARD NORME INTERNATIONALE Fibre optic active components and devices – Performance standards – Part 1 General and guidance Composants et dispositifs ac[.]
General
In the preparation of a performance standard, the following items shall be considered and instructions pertaining to them included
Product definition
The product to which the performance standard relates shall be clearly defined.
Tests
The tests to be carried out on the product in order for it to meet the performance standard shall be clearly defined No ambiguity or options shall be allowed
The tests selected combined with the severities/durations, groupings/sequencing, method used and pass/fail criteria should be indicative of a defined product location within a service environment
Each test must have a clearly defined method, preferably selected from IEC referenced tests If IEC methods are not applicable, alternative test methods may be specified Any new test methods that are not previously defined should be detailed in an annex of the performance standard.
Details
All tests and measurements outlined in a performance standard must include specific severities, durations, and relevant details These elements should directly align with the requirements for a product's location within its intended service environment Clarity is essential; therefore, no ambiguity or alternative interpretations will be permitted.
Requirements
To ensure compliance with the standard, each test and measurement must clearly specify the performance requirements, leaving no room for ambiguity.
Sample size
The sample size for each test shall be defined in an annex of the performance standard No deviations shall be allowed.
Groupings/sequences
Test groups and sequences must be outlined in an annex as specified by the user, user group, or manufacturer The annex should also detail the number of samples for each test group, with the possibility of reducing sample sizes if the costs of active devices are prohibitively high.
Pass/fail criteria
The pass/fail criteria shall be unambiguously stated for each test within the performance standard No deviation or exceptions shall be allowed.
Performance standard test report
To ensure compliance with performance standards, a test report is essential This report, which may be generated by an independent testing laboratory, must clearly indicate that the tests were conducted according to the performance standard's requirements Additionally, it should include comprehensive details of the tests performed, along with a clear pass or fail declaration.
Products that do not pass specific tests will be documented in the performance standard test report, which will include the reason for the failure and a description of any corrective actions taken.
If no design changes are made to the product, the test or test sequence where the failure occurred shall be rerun with the results of both the tests reported
Any design changes shall be identified in the performance standard test report The full set of performance tests must be rerun and the results reported in this case.
Environmental aspects
This specification does not address the requirements for minimizing negative environmental impacts throughout the entire life cycle of products Environmental considerations should be applied in accordance with the guidelines outlined in IEC Guide 109.
Tests and severities for performance standards
This annex contains the preferred tests and recommended severities associated with these tests for typical system locations in which active fibre optic components may be installed (see
Tests are organized to be conducted in groups and in a specified order, aiming to replicate specific conditions that the product may encounter.
The general system location for which performance standard schedules are provided is given in Table A.1

NORMES DE PERFORMANCES – Partie 1: Généralités et lignes directrices
The International Electrotechnical Commission (IEC) is a global standards organization comprising national electrotechnical committees Its primary goal is to promote international cooperation on standardization in the fields of electricity and electronics To achieve this, the IEC publishes international standards, technical specifications, technical reports, publicly accessible specifications (PAS), and guides, collectively referred to as "IEC Publications." The development of these publications is entrusted to study committees, which allow participation from any interested national committee Additionally, international, governmental, and non-governmental organizations collaborate with the IEC in its work The IEC also works closely with the International Organization for Standardization (ISO) under an agreement between the two organizations.
Official decisions or agreements of the IEC on technical matters aim to establish an international consensus on the topics under consideration, as the relevant national committees of the IEC are represented in each study committee.
The IEC publications are issued as international recommendations and are approved by the national committees of the IEC The IEC makes every reasonable effort to ensure the technical accuracy of its publications; however, it cannot be held responsible for any misuse or misinterpretation by end users.
To promote international consistency, the national committees of the IEC commit to transparently applying IEC publications in their national and regional documents as much as possible Any discrepancies between IEC publications and corresponding national or regional publications must be clearly stated in the latter.
The IEC does not issue any conformity certificates itself Independent certification bodies provide conformity assessment services and, in certain sectors, have access to IEC conformity marks The IEC is not responsible for any services performed by these independent certification bodies.

Performance standards define standardized electro-optical performance under a set of prescribed conditions and include a series of tests and measurements, which may or may not be grouped in a specific program, with clearly defined conditions, severities, and acceptance/rejection criteria These tests are intended for initial design verification to demonstrate the products' ability to meet the requirements of a specific application, market sector, or user group.
The other sections of this standard include sets of performance criteria that have been standardized for international use A product that meets all the requirements of a performance standard can be declared compliant with that standard.
Les produits d’un fabricant qui sont soumis aux essais selon une norme de performances fonctionneront ensemble dans la limite des critères établis par la norme de performances
However, there is no guarantee that products with the same standardized interface, which have been independently tested according to a performance standard, will achieve the same optical performance levels when paired together, even if they come from different suppliers.
