1 Scope

The purpose of this part of IEC 61300 is to describe the procedure required to measure the spring compression force of the coupling sleeve for rectangular ferrule multi-fibre connectors

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies

None

3 General description

The measurement of the coupling sleeve compression force is made with the optical connector fixed Then the coupling sleeve is moved to the stipulated position to measure the coupling sleeve compression force with a force gauge

4 Apparatus

4.1 General

The apparatus consists of the following elements See Figures 1 and 2

4.2 Fixture

The fixture shall be able to hold the optical connector without influencing the measurement of the spring compression force of the coupling sleeve The fixture shall be able to hold the optical connector with a force larger than the stipulated coupling sleeve compression force If measurement is repeated, the location of the optical connector shall not be changed

4.3 Force transfer cup

The force transfer cup shall push only the coupling sleeve without contacting any other elements of the optical connector

4.4 Force gauge

The force gauge shall be able to measure at least from 2,9 N to 6,9 N (compression force range) The force gauge is placed so that its pushing direction is the same as the coupling sleeve steering direction

BS EN 61300-3-48:2013

– 6 – 61300-3-48  IEC:2013(E)

4.5 Sliding stage

The sliding stage shall not impede the location of the force gauge (4.4) and should be placed

so that it can move in the same direction as the coupling sleeve

4.6 Observation instrument

The observation instrument shall have sufficient magnification to verify that the coupling sleeve is located at the stipulated location within a ±0,1 mm margin

5 Procedure

The procedure is as follows:

a) Set the optical connector under test into the fixture

b) Have the pushing part contact the edge of the coupling sleeve under test and confirm that

it is located such that only the coupling sleeve is pushed, checking that the force transfer cup does not interfere with the optical connector

c) Set the observation instrument to confirm that the coupling sleeve is properly compressed

to the intended position

d) Use the force gauge to set the force transfer cup and coupling sleeve at the measurement position Confirm the location of the coupling sleeve with the observation instrument When the edge of the coupling sleeve is within a ±0,1 mm range from the measurement position, read the value of the force gauge

6 Details to be specified

The following details, as applicable, shall be stated in the relevant specification:

– maximum allowed compression force for the force gauge;

– pre-conditioning procedure;

– recovery procedure;

– acceptance/failure criteria;

– number of times the test is performed on each component;

– any deviation from measuring procedure;

– measurement uncertainty
