Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-43: Tests - Screen testing of return loss of single mode PC optical fibre connectors
Applies where optical fibre connectors are in practical use and it is necessary to ensure a designed minimum return loss of the connector at a mating point. Aims at screening single mode physical contact (PC) optical fibre connectors of an optical patch cord and an optical pigtail cord in terms of return loss, thus ensuring minimum return loss when the connectors, which have been screen tested by this method, are randomly concantenated each other in the field.

Dispositifs d'interconnexion et composants passifs à fibres optiques - Méthodes fondamentales d'essais et de mesures - Partie 2-43: Essais - Sélection des connecteurs PC pour fibres optiques monomodes en fonction de leur puissance réfléchie
S'applique lorsque des connecteurs pour fibres optiques sont utilisés et qu'il est nécessaire de garantir une puissance réfléchie minimale de conception du connecteur en un point d'accouplement. A pour objet de procéder à une sélection des connecteurs pour fibres optiques monomodes à contact physique (PC) montés sur cordon et à fibres amorces, en fonction de leur puissance réfléchie, pour garantir ainsi une puissance réfléchie minimale lorsque les connecteurs, qui ont été sélectionnés par cette méthode, sont concaténés de manière aléatoire dans le terrain.

The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, 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 InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment 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 subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61300-2-43 has been prepared by subcommittee 86B: Fibre opticinterconnecting devices and passive components, of IEC technical committee 86: Fibre optics.The text of this standard is based on the following documents:FDISReport on voting86B/1215/FDIS86B/1252/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.IEC 61300 consists of the following parts, under the general title Fibre optic interconnectingdevices and passive components – Basic test and measurement procedures:–part 1 : General and guidance–part 2 : Tests–part 3 : Examinations and measurementsAnnex A is for information only.

This polishing process results in a thin damaged layer at the fibre endface of theconnector. In silica fibres, the refractive index of the damaged layer is slightly higher than thatof original fibre. This high refractive index layer generates optical reflection. When PC
