IEC 61753-2-1:2000 pdf download.Fibre optic interconnecting devices and passive components performance standard-Part 2-1:Fibre optic connectors terminated onsingle-mode fibre for category U-Uncontrolled environment.

4 Tests
All test methods are in accordance with a specific IEC 61300 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 fo 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 tesi, 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 tesls 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 lEG interlace 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.
6 Fibre/cable Allowable change in attenuation: lEG 61 300-2-4
retention
0,20 dB at 1 550 nm ± 30 nm Magnitude and rate of application of the tensile
load:
Attenuation shall be measured before,
during and after the test 100 N ± 5 N at a speed of 5 N/s for reinforced
cables
Return loss shall be measured before,
during and after the test and shall satisfy 5 N ± 0,5 N at a speed of 0,5 N/s for coated fibres
the requirements for the specified class .
Point of application of tensile load:
The change in attenuation measurement
shall be made against randomly selected 0,3 m from the endface of the connector
plugs Duration of the test (maintaining the load):
The initial attenuation shall satisfy the 120 s at 100 N for reinforced cable
requirements for the specified class
60 s at 5 N for coated fibres
Sampling rate:
Losses shall be measured at least once after the load has reached its maximum level and been maintained for a minimum period of 30 s Method of mounting:
The connector shall be rigidly mounted such that the load is applied to the fibre/cable retention mechanism and not to the connector coupling mechanism.
Specimen shall be optically functioning
Preconditioning procedure:
Clean the mechanical and optical alignment parts of the specimen according to the manufacturer’s instructions.
7 Torsion Allowable change in attenuation: lEG 61 300-2-5
0,20 dB at 1 550 nm ± 30 nm Magnitude and rate of application of the tensile
load:
Attenuation shall be measured before,
during and after the test 15 N at a speed of 1 N/s for reinforced cable
Return loss shall be measured before, 2 N at a speed of 0,1 N/s for coated fibre during and after the test and shall satisfy .
the requirements for the specified class Point of application of tensile load:
The change in attenuation measurement 0,2 m from the endface of the connector shall be made against randomly selected Duration of the test: 25 cycles ± 180° plugs
Sampling rate:
The initial attenuation shall satisfy the
requirements for the specified class Losses shall be measured at least once after the load has reached maximum level
Specimen shall be optically functioning
Preconditioning procedure:
Clean the mechanical and optical alignment parts of the specimen according to the manufacturer’s instructions
Recovery procedure:
Clean the mechanical and optical alignment parts of the specimen according to the manufacturer’s instructions before final measurement.
