20、 61300 describes a procedure to measure guide hole and alignment pin deformation constant, CDfor 8 degree angled PC rectangular ferrule multi-fibre connectors. 2 General description 2.1 General Alignment pin and ferrule deformation dependence on applied force at the pin edge can vary for different f
21、errule design attributes including material properties, internal geometry and surface roughness. The amount of deformation influences the amount of y-direction translation and therefore the nominal y-offset location of the fibre cores, Yi. Yiis described by the next expression and shown in Figure 1:
22、 Yi= (ID-OD)/2 + CDwhere is the coefficient that depends on the difference between guide hole pitches for mated plugs; ID is the inside diameter of the guide hole; OD is the outside diameter of the alignment pin; CD is the alignment pin and guide hole deformation constant for an applied force of 0,7

MT ferrule position MT ferrule shall be centred on gauge block Relative humidity RH (50,0 10,0) % RH Maximum pin size 0,6988 mm 3 Apparatus 3.1
25、Precision linear scale The structure of precision linear scale used for the CDmeasurement is shown in Figure 2. The apparatus consists of a measurement force setter, a force indicator, a position indicator, a scale head touching the samples to be measured and a scale stage. The linear scale has a re
26、solution of 1/100 m and the measurement force setting up to 2,20 N. The measurement procedure is as follows: a) Measurement force applied between the scale head and the scale stage of the linear scale is adjusted by the measurement force setter. b) The measurement force is read directly from the for
27、ce indicator of the main body.

A gauge block is employed due to its very fine surface roughness, surface hardnes

Alignment pins are inserted into the guide holes with the pin top protrusions from the ferrule less than 0,5 mm, as shown in Figure 3. BS EN 61300-3-52:

31、rrule need to be cleaned. The end of the alignment pin shall protrude from the ferrule by less than 0,5 mm. b) The sample is placed stably between the scale head and the scale stage with the maximum measurement force as shown in Figure 2. Put the scale head in contact with the protruding guide pin a
32、nd set to zero for displacement. c) The measurement force is set to the minimum, 0,5 N, and the position indicator display is read. The measurement force is increased in constant steps; at each step, the position indicator display is read. The setting is changed to the maximum measurement force, 1,4
33、 N, and the position indicator display is read. d) This measurement is repeated five times for each guide hole, and the average values of the data are plotted in the graph, then a fitted line is applied to the plots. Then the inclination of deformation to the force is obtained. The CDvalues for a 9,
34、8 N mating force are obtained for the deformation at 0,7 N ( 9,8 N x sin8 x 0,5) of the measuring force. 5 Details to be specified The following details shall be stated in the relevant specification: procedure of preparations; gauge block specification; alignment pin specification; acceptable value
35、of guide hole and alignment pin deformation constant CD; maximum measurement force applied to the sample; difference from this method. measurement uncertainty.
