National foreword

This British Standard is the UK implementation of EN 61753-022-2:2013.
It is identical to IEC 61753-022-2:2012. It supersedes
BS EN 61753-022-2:2003, which is withdrawn.
The UK participation in its preparation was entrusted by Technical Committee
GEL/86, Fibre optics, to Subcommittee GEL/86/2, Fibre optic interconnecting
devices and passive components.
A list of organizations represented on this committee can be obtained on
request to its secretary.
This publication does not purport to include all the necessary provisions of a

Test

All test methods are in accordance with the IEC 61300 series.
The connector shall be terminated onto multimode fibre as per IEC 60793-2-10, fibre type A1a
or A1b, in either secondary coated or reinforced cable format.
Each test defines the number of samples to be evaluated.
The samples 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 one central wavelength only, this shall be either
850 nm ± 30 nm.
Source characteristics shall be S2, S3 and detector D1, as specified in IEC 61300-3-4.
Launch conditions shall be in accordance with IEC 61300-1.
The full set of tests shall be carried out for all fibre types for which compliance to this
standard is claimed.
For different cable structures only requalification to tests 4, 6, 9, 10, 11, 12, 13 and 14 is
requested.
Change in attenuation, for the purpose of the test, is defined as the peak-to-peak variation
and shall be measured using IEC 61300-3-3. For monitoring intermittent discontinuities during
a test, IEC 61300-3-28 shall be used.

Sample size

For the purposes of this standard, a sample is a connector set, defined as the complete set of
connector components required to provide demountable coupling between one or more pairs
of optical fibres, i.e. “cable-plug-adapter-plug-cable” or “cable-socket-plug-cable”. The length
of cable (or fibre) inside the chamber on each side of the connector set should be 1,5 m
minimum.
The sample sizes to be used for the tests shall be as defined in Annex A. Samples may either
be a new product or sourced from a previous test.
