3Description
The parent connector for type SC-RJ connector family is a duplex plug connector set ofplug/adaptor configuration which is characterised by 2,5 mm nominal ferrule diameter. Theconnector includes a push-pull coupling mechanism，which is spring loaded relative to theferrules in the direction of optical axes.The plug has three male keys. Two of them in eachcase are used to orient and limit the relative positions between the two ferrules and thecomponents (SC simplex connector) to which they are mated and one key which defines thegeneral orientation of the duplex connector. The optical alignment mechanism of the adaptoris of a resilient sleeve style.For the active device interface, the alignment mechanism can beof both type: rigid bore or resilient sleeve.
Interfaces
4.1General
This standard contains the following standard interfaces for the type SC-RJ connector familyas follows:
To avoid mating fibre of different sizes (for silica fibres 24-1 , 24-2 with the HCS interface 24-3 or with the POF interface 24-4) at least a colour coding system shall be applied not only on the connector but also on the adaptor side. For a higher security level a mechanical coding shall be implemented to eliminate an incorrect fibre type mating, see in detail Annex B, Figure B.1 . In addition to the interfaces defined in this connector family, the SC simplex plug connectors according to IEC 61 754-4 (Interfaces 4-1 , 4-5, 4-6 and 4-7) can be mated with SC-RJ adaptor connector interface 24-5 and SC-RJ active device interface 24-6.
