Patent ID: 7699533

Claim:
A system for providing selective interconnection between a first optic fibre and a second optic fibre, the system comprising: a set of receptacles, each receptacle comprising a pair of back-to-back receptacle sockets, each of said sockets conforming substantially to a standard and each socket in said pair of back-to-back receptacle sockets comprising a receptacle keying part configured to a same one of a plurality of predefined receptacle keying geometries, said receptacle keying part for each receptacle in said set of receptacles being different; a set of connector plugs, each plug in said set of plugs conforming substantially to said standard and adapted for insertion into a first of said back-to-back receptacle sockets, said each plug comprising a connector keying part configured to one of a plurality of predefined connector keying geometries, said connector keying part for each plug in said set of connector plugs being different; a first connector plug terminating the first optic fibre and a second connector plug terminating the second optic fibre, each of said first plug and said second plug selected from said set of connector plugs and conforming substantially to said standard, said plug comprising a connector keying part configured to one of a plurality of predefined connector keying geometries; and wherein one and only one of said predefined connector keying geometries corresponds to one and only one of said predefined receptacle keying geometries; and wherein when said receptacle keying geometry of said receptacle keying part of said first socket corresponds to a connector keying geometry of a connector keying part of said first plug and said receptacle keying geometry of said receptacle keying part of said second receptacle socket corresponds to a connector keying geometry of a connector keying part of said second plug, said first plug can be inserted in said first socket and said second plug can be inserted in said second socket bringing the first optic fibre into axial alignment with the second optic fibre.
