IEC 61754-18 pdf download Fibre optic connector interfaces – Part 18: Type MT-RJ connector family
1 Scope
This part of IEC 61 754 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 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 interfaces 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 type MT-RJ connector family.
