5、gate them in the UK. - A list of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period oftime during
6、the change over from one numbering system to the other, publications may contain identifiers from both systems.

22、e This part of IEC 61754 defines the standard interface dimensions for the type MT-RJ family of connectors. 2 Description The parent connector for the type MT-RJ connector family is a plug connector having single or multiple fibres in a rectangular ferrule nominally 4,4 mm x 2,5 mm aligned by two 0,
23、7 mm diameter pins and corresponding holes. The connector includes a single coupling latch and a ferrule spring loaded in the direction of the optical axis. The plug connector has a single male key which may be used to orientate the connector and the component to which it is mated. Connector interfa
24、ces are configured as a plug without pins, an adaptor and a plug with pins or alternatively as a plug without pins and a receptacle with pins. Adaptors use ribs to pre-align ferrules. Receptacles with and without ribs are defined. 3 Interfaces Subsequent pages define the standard interfaces for the
25、type MT-RJ connector family. This standard contains the following standard interfaces: Interface 61754-18-1 MT-RJ plug connector interface, without pins, consisting of Interface 61754-18-1-1 for single fibre Interface 61754-18-1-2 for two fibres with a pitch of 0,25 mm Interface 61754-18-1-3 for two
