36、as defined in 7.4 and 7.5. The connectors under test shall be terminated onto single-mode fibre per type B1.1 or B1.3 of IEC 60793-2-50, in either secondary coated or cable format. The connector interface standard shall meet the dimensions of IEC 61754 and the connector optical interface standard sh

37、all meet the relevant requirements of IEC 61755. The optical connector requirements shall be met in order to be in accordance with IS0 11801. Each test defines the number of samples to be evaluated. The sample set used for the first test is to be composed of randomly selected and previously unstress

38、ed new samples. The optical criteria for each test shall be as defined in 7.4. 5 Test report Fully documented test reports and supporting evidence shall be prepared and available for inspection as evidence that the tests have been carried out and the results are satisfactory.

39、6 6 Reference components No reference components are required to perform the tests in this standard. 7 Performance requirements 7.1 Dimensions Dimensions shall comply with the appropriate IEC interface standard as defined in IEC 61754. 7.2 Sample size, test sequencing and grouping For the purposes o

40、f this standard, a sample is composed of pigtail assemblies and jumper cable assemblies (see Clause 3). The sample sizes to be used for the tests shall be as defined in Annex A. There is no defined sequence or grouping in which the tests shall be run. Samples for the first test (attenuation) are to

41、be randomly selected and randomly mated new products. Samples for the second test (return loss) are the same plugs selected and mated for the first test. Samples for subsequent tests may be randomly selected and randomly mated new products or the same plugs. 7.3 Endface geometry The connector endfac

42、e shall comply with the endface geometry requirements of the applicable IEC optical interface standard as defined in 61755-3. Compliance with the appropriate optical interface standard shall be confirmed on all samples before the start of testing and after all of the tests have been completed. Non-c

43、ompliance with the endface geometry requirements of the applicable optical interface standard on any connector tested results in a failure of this performance standard. 7.4 Performance criteria The optical performance levels shall meet the requirements of Grade C/3 as defined in Table A.12 of IEC 61
