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 shall
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 unstressed new samples.

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 of 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 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 endface 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-compliance with the endface geometry requirements of
the applicable optical interface standard on any connector tested results in a failure of this
performance standard.
