IEC 61753-2-1 :2000 pdf download-Fibre optic interconnecting devices and passive components performance standard – Part 2-1 : Fibre optic connectors terminated on single-mode fibre for category U – Uncontrolled environment.
3 Definitions For the purpose of this part of IEC 61 753, the following definitions apply. 3.1 loss variation attenuation from the value measured before the commencement of the test 3.2 sample connector set, defined as the complete set of connector components required to provide demountable coupling between one or more pairs of optical fibres
4 Tests All test methods are in accordance with a specific IEC 61 300 part. The samples shall be terminated onto single-mode fibre as per IEC 60793-1 -1 , category B.1 .1 , in either secondary coated or reinforced cable format. Each test defines the number of samples to be evaluated. The connector pairs used for each test are intended to be previously unstressed new samples, but may be selected from previously used samples, if so desired. All optical testing shall be carried out at 1 550 nm ± 30 nm, unless otherwise specified. Change in attenuation is, for the purpose of the test, defined as peak to peak variation. 5 Test report Fully documented test reports and supporting evidence shall be prepared and made available for inspection as evidence that the tests have been carried out and complied with. 6 Reference components Where the test methods used within this standard require the use of reference components, they shall have characteristics as defined in annex B. 7 Performance requirements 7.1 Dimensions Dimensions shall comply with either the appropriate IEC interface standard or with those given in appropriate manufacturers’ drawings, where the IEC interface standard does not exist or cannot be used. 7.2 Sample size, sequencing and groupings The length of cable (or fibre) on each side of the connector set should be 1 ,5 m minimum. The sample sizes, sequencing and grouping to be used for the tests shall be as defined in annex A. Samples may either be new product or sourced from a previous test.
