4、rests informed - monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, ali IEC publications have the number 60000 added to the old number. For i
5、nstance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems.

19、onnector family I Scope This part of IEC 1754 defines the standard interface dimensions for the type CF08 family of connectors. 2 Description The parent connector for the type CF08 connector family is a single-way plug connector which is characterized by a conical ferrule butting against a 4 mm diam
20、eter sphere or equivalent. It includes a push-pull coupling mechanism and a ferrule spring loaded in the direction of the optical axis. The plug has a single male key which may be used to orient and limit the relative rotation between the connector and the component to which it is mated. 3 Interface
21、s This standard contains the following standard interfaces: a) interface 8-1: plug connector interface; b) interface 8-2: adapter - for plugiadapterlplug configuration; c) interface 8-3: receptacle connector - for plug/receptacle/optical component configuration.

In one opt
32、ion, the reference sphere has an elastomeric part definitely linked with it. The thickness and the hardness of the elastomeric material is such that there is always a physical contact between the optical faces and the elastomeric material. The other option, without elastomeric, is generally used for
