26、EASUREMENT PROCEDURES Part 3-52: Examinations and measurements Guide hole and alignment pin deformation constant, C Dfor 8 degree angled PC rectangular ferrule, single mode fibres FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisi
27、ng all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standard
28、s, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparat
29、ory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizat
30、ions. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of r
31、ecommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation b
32、y any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional
33、 publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by i
34、ndependent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for
35、any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Norma
36、tive references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held respon
37、sible for identifying any or all such patent rights. International Standard IEC 61300-3-52 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FD

39、parts in the IEC 61300 series, published under the general title, Fibre optic interconnecting and passive components Basic test and measurement procedures, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date
40、indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61300-3-52 IEC:2014 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC
41、 TEST AND MEASUREMENT PROCEDURES Part 3-52: Examinations and measurements Guide hole and alignment pin deformation constant, C Dfor 8 degree angled PC rectangular ferrule, single mode fibres 1 Scope This part of IEC 61300 describes a procedure to measure guide hole and alignment pin deformation cons
42、tant, C Dfor 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 ferrule design attributes including material properties, internal geometry and surfac
43、e roughness. The amount of deformation influences the amount of y-direction translation and therefore the nominal y-offset location of the fibre cores, Y i . Y iis described by the next expression and shown in Figure 1: Y i (ID-OD)/2 C Dwhere is the coefficient that depends on the difference between
44、 guide hole pitches for mated plugs; ID is the inside diameter of the guide hole; OD is the outside diameter of the alignment pin; C D is the alignment pin and guide hole deformation constant for an applied force of 0,7 N to each hole corresponding to the nominal mating force value of 9,8 N.

47、 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 resolution of 1/100 m and the measurement force setting up to 2,20 N. The measurement procedure is a
48、s 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 force indicator of the main body. 61300-3-52 IEC:2014 7 Scale head touching on the pin at the ferrule
