IEC 61753-2-1-2000 pdf free 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.
This part of lEC 61753 contains the minimum requirements and severities which a single-modeconnector/cable assembly must satisfy in order to be considered as meeting category u(uncontrolled environment) of lEC 61753-1, as defined in annex A of lEC 61753-1.
This standard contains optional grades of optical performance for the attenuation random mateand return loss tests.

4Tests
All test methods are in accordance with a specific lEC 61300 part.
The samples shall be terminated onto single-mode fibre as per lEC 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 availablefor 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 lEC interface standard or with those givenin appropriate manufacturers’drawings，where the lEC interface standard does not exist orcannot be used.
7.2Sample 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 inannex A.Samples may either be new product or sourced from a previous test.IEC 61753-2-1 pdf download.
