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.

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.

4.1

Apparatus
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.

61300-3-48  IEC:2013(E)

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.

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.

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.
