1754-1 © IEC:1996 – 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION_________FIBRE OPTIC CONNECTOR INTERFACES –Part 1: General and guidanceFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising allnational electrotechnical committees (IEC National Committees). The object of the IEC is to promote internationalco-operation on all questions concerning standardization in the electrical and electronic fields. To this end and inaddition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technicalcommittees; any IEC National Committee interested in the subject dealt with may participate in this preparatorywork. International, governmental and non-governmental organizations liaising with the IEC also participate in thispreparation. The IEC collaborates closely with the International Organization for Standardization (ISO) inaccordance with conditions determined by agreement between the two organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested National Committees.3)The documents produced have the form of recommendations for international use and are published in the form ofstandards, 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. Any divergencebetween the IEC Standard and the corresponding national or regional standard shall be clearly indicated in thelatter.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 subject ofpatent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 1754-1 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/833/FDIS86B/923/RVDFull information on the voting for the approval of this standard can be found in the report on votingindicated in the above table.Annex A forms an integral part of this standard.Annexes B and C are for information only.SIST EN 61754-1:1997



1754-1 © IEC:1996 – 7 –INTRODUCTIONAn optical connector interface is a collection of physical features on a connector assembly thatdefines a specified style. It consists of those minimum features that are functionally critical (i.e.,work together) during the mating and unmating sequences of the connector with its counterpartcomponent. The interface defines the sizes, relative locations, and tolerances for each of thefeatures. In addition, it defines the location for the optical datum target.This part of IEC 1754 contains those interfaces that have been standardized for international use.It consists of individual sets of connector interfaces. Each set contains at least two counterpartinterfaces that mate together. The standards therefore ensure that the two counterpart interfaceswill mate and that they will mate with a specified fit tolerance between the mating features.It is important to emphasize that the standard interfaces define physical dimensions only and thatno guarantee of performance is implied, nor should be assumed, for connectors that comply withthe standards. Manufacturers using the standards are responsible for positioning the optical fibreor device port at the optical datum target location with the accuracy necessary to meet theirrequired performance.An optical connector, by definition, mates with another optical component. Typically, the matingcomponent is another optical connector. In many cases, however, the mating component is notanother connector but rather an optical component such as a switch, a branching device, or anactive device. The portion of the component that contains the mating features to receive andposition the connector is called an adaptor.This standard makes a distinction between a connector interface and an adaptor interface. Anadaptor interface may not contain an optical datum target as in the case where two connectorplugs are engaged and are aligned by an alignment sleeve. However, the adaptor does contain anoptical datum target whenever it positions an optical fibre or optical fibre waveguide, as in anactive device or branching device.SIST EN 61754-1:1997
