ABSTRACT:
A device for connecting a first optical fiber end held by a first connector plug selectively to second or third optical fiber ends held by different types of connector plugs, in which each different type of plug has an associated connector socket, these sockets each including a non-circular connector flange and each having a ferrule alignment sleeve held by a retainer bushing projecting outwardly from the connector flange, the alignment sleeves being of the type suitable for receiving cylindrical ferrules attached to each fiber end. The device comprises a fixed part having an aperture extending between its inner and outer surfaces, and having a connector adapter projecting from the inner surface and suitable for receiving the first connector plug, and having a radially extending outer surface portion accessible from the outer surface and surrounding a recess suitable for receiving the retainer bushing of another connector plug. A retainer is rotatably mounted on the fixed part co-axially with the adapter and has opposed flange portions spaced from the outer surface portion, which flange portions define a non-circular opening such that opposite sides of one of the non-circular connector flanges can pass between said flange portions when aligned therewith to bring the alignment sleeve retainer bushing into the adapter recess, and such that opposite corners of the connector flange can be retained by the flange portions upon rotation of the retaining means into a locked position. The device is useful for mounting on the outside of a testing instrument which needs to be connectible to optical fibers having different connector plugs.
