4、 OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-35: Examinations and measurements Fibre optic cylindrical connector endface visual inspection FOREWORD A PAS is a technical specification not fulfilling the requirements for a standard, but made availa
5、ble to the public. IEC-PAS 61300-3-35 has been processed by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this PAS is based on the following document: This PAS was approved for publication by the P-members of th
6、e committee concerned as indicated in the following document: Draft PAS Report on voting 86B/1677/PAS 86B/1701/RVD Following publication of this PAS, the technical committee or subcommittee concerned will investigate the possibility of transforming the PAS into an International Standard. 1) The IEC
7、(International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and
8、electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
9、 and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or a
10、greements of the 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 National Committees. 3) The documents produced have the form of recommendations for internati
11、onal use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transpar
12、ently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendere
13、d responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent
14、rights. Copyright 2002, IEC 3 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-35: Examinations and measurements Fibre optic cylindrical connector endface visual inspection 1 Scope The purpose of this part of IEC 61300 is to quantitatively asses
15、s the endface quality of a polished fiber optic connector. The information is intended for use with other standards which set requirements for allowable surface defects such as scratches, pits and debris which may affect optical performance. In general, the methods described in this document apply t
16、o fibers contained within a ferrule, however portions are applicable to non-ferruled connectors. Those portions are identified where appropriate. 2 Normative references The following normative document contains provisions which, through reference in this text, constitutes provisions of this part of
17、IEC 61300. IEC 61300-1 Ed. 1.0b: 1995, Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 1: General and guidance 86B 3 General description Two methods are described: (A) Optical microscope and (B) CCD array camera with monitor. In method A, the
18、 required equipment is an optical microscope capable of direct illumination with a calibrated eyepiece reticle to measure the size of features in the image. In method B, an optical microscope is used in conjunction with a CCD array camera to project an image onto a video monitor at a known magnifica
19、tion. In both methods A and B, features are identified and measured by an operator. 3.1 Morphological Definitions of Defect Features For purposes of this document the following defects shall apply for all measurement methods. Scratches: permanent linear surface features derived from polishing or han
20、dling Pits: permanent non-linear features caused by surface damage during polishing or handling. Cracks: permanent fracture lines that may extend to the surface of the fiber Surface debris: non-permanent features that can be removed by cleaning. 3.2 Measurement conditions No restrictions are placed
