Embodiments of the invention include a method and adaptor apparatus for
optically connecting optical fibers of a standard ferrule based parallel
multi-mode fiber format plug with photonic devices of a connector sleeve
arranged in accordance with a miniature form factor format. The adaptor
includes an adaptor jacket having a first end that is optically connected
to a second end. The first end is configured to receive a connector plug
having optical fibers arranged in a standard ferrule based parallel
multi-mode fiber format. The second end is formatted for connection with a
miniature form factor connector sleeve having an optical subassembly
fitted thereon. Thus, the photonic devices of an optical subassembly
arranged in the miniature form factor format can be optically coupled, via
the adaptor jacket, to corresponding optical fibers of the connector plug
arranged in a standard ferrule based parallel multi-mode fiber format.
