22、 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 2,5 mm aligned by two 0,7 mm dia
23、meter 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 interfaces are
24、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 type MT-
25、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 fibres
