23、ection of physical features on a connector assembly that defines a specified style. It consists of those minimum features that are functionally critical (i.e. work together) during the mechanical mating and unmating sequences of the connector with its counterpart component. The interface defines the
24、 size, relative location and tolerance for each of the features. In addition, it defines the location for the optical datum target. This part of IEC 61754 contains those interfaces that have been standardized for international use. It consists of individual sets of plug and adaptor interfaces. Each
25、set contains at least two counterpart interfaces that mate together. The standards therefore only ensure that the two counterpart interfaces will mate together and that they will mate with a specified fit tolerance between the mating features. It is important to emphasize that the standard interface
26、s define physical dimensions only and that no guarantee of performance is implied, nor should be assumed, for connectors that comply with the standards. Manufacturers using the standards are responsible for positioning the optical fibre or device port at the optical datum target location with the ac
27、curacy necessary to meet their required performance. An optical connector, by definition, mates with another optical component. Typically, the mating component is another optical connector. In many cases, however, the mating component is not another connector but rather an optical component such as
28、a switch, a branching device or an active device. The portion of the component that contains the mating features to receive and position the connector is called an adaptor. This standard makes a distinction between a connector interface and an adaptor interface. An adaptor interface may not contain
29、an optical datum target as in the case where two connector plugs are engaged and are aligned by an alignment sleeve. However, the adaptor does contain an optical datum target whenever it positions an optical fibre or optical fibre waveguide, as in an active device or branching device. BS EN 61754-1:
