IEC 62149-1:2011 pdf – Fibre optic active components and devices – Performance standards -Part 1: General and guidance.
The tests selected combined with the seventies/durations, groupings/sequencing, method used and pass/tail criteria should be indicative of a defined product location within a service environment,
The test method to be used shall be clearly defined for each test. Wherever possible the test method shall be selected from IEC referenced tests; wIere this is not possible other test methods may be defined. If a previously undefined test method is used, the test method and details to be specified shall be included in an annex of the performance standard.
Seventies, durations and the details to be considered, shall be given for all tests and measurements presented in a performance standard. These should be directly related to the requirements specified for a product location within a service environment to which the performance standard is intended to correspond. No ambiguity or options shall be allowed.
The performance requirements that must be satisfied in order for the product to comply with the standard shall be specified for each test and/or measurement. No ambiguities shall be allowed.
4.6 Sample size
The sample size for each test shall be defined In an annex of the performance standard. No deviations shall be allowed.
Test groups and test sequences shall be defined in an annex as required by Ihe user, user group or manufacturer. The number of samples for each test group shall also be defined in the annex. Where prohibitive cost is associated with the active devices, numbers of samples may be reduced
4.8 Passfail criteria
The passifail criteria shall be unambiguously stated for each test within the performance standard. No deviation or exceptions shall be allowed
4.9 Reference product definition
Where a reference product is called for in any of the test and measurement methods used within a performance standard, the reference product shall be clearty defined in an annex of the performance standard.
4.10 Performance standard test report
Conformance to a performance standard shall be supported by a test report. The test report may be prepared by an independent leSt laboratory. The test report shall clearly demonstrate that the tests were carried out as per the requirements of the performance standard and provide full details of the tests, together with a pass/fail declaration.
Any product failing a particular test or sequence of tests shall be reported in the performance standard test report. The cause of the failure shall be given and any corrective action taken shall be described
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.
Table A.1 indicates the ambient temperature ranges for optical network equipment under various environmental categories and does not indicate the operatin9 temperature ranges for active optical components. The operating temperature range for each active component shall be specified by its case temperature, unless otherwise stated, and defined in each performance standard document in order that the component operates under the specific environmental category described in Table Al. The system designer should design the heat flow of the equipment to maintain the case temperature 01 the installed active components within their specifications. The performance tests for each active component should be carried Out within the specified case temperature range.
