Abstract

Claims (24)

1. A network comprising:

a plurality of different transceivers, each different transceiver having a different receptacle for facilitating a connection to different information networks requiring different access authorization, said each different transceiver optically or electrically coupled to one and only one different information network, said each different receptacle having an inner surface with a unique first geometry; and

a plurality of different plugs, said each different plug having a unique second geometry, said each unique first geometry corresponds to one, and only one, unique second geometry of a plug such that said plugs and receptacles having corresponding unique first and second geometries are mating pairs.

2. The network of claim 1 , wherein said first geometry includes a key and said second geometry includes a slot.

3. The network of claim 2 , wherein said each receptacle comprises a receptacle having a tub, said tub comprising said key and a plurality of ribs extending inward, said each plug comprising a housing and a ferrule contained within the housing, said housing comprising said slot for cooperating with said key and secondary slots for cooperating with said ribs, said slot and said secondary slots receiving said key and said ribs to effect pre-alignment of said ferrule before final mating of said ferrule.

4. The network of claim 1 , wherein said transceivers are LC transceivers.

5. The network of claim 1 , wherein said transceivers are MPO transceivers.

6. A secure transceiver system for use with a connector system comprising a set of plugs, each plug having a housing having a front and back orientation and having a front face defining an opening, a ferrule being disposed within said opening, said housing defining a first keying element on said front face around said opening, said first keying element for each plug of said set of plugs being different; said secure transceiver system comprising:

a set of transceivers, each transceiver having a different receptacle, each receptacle having an opening to receive said plug and a ferrule-receiving portion to receive said ferrule, said ferrule-receiving portion defining a second keying element to cooperate with said first keying element, said second keying element for each receptacle being different and being adapted to cooperate with one and only one of said first keying elements, wherein plugs and receptacles having keying elements that cooperate are mating pairs.

7. The secure transceiver system of claim 6 , wherein said first and second keying elements are one or more keys and one or more slots for receiving said keys, respectively.

8. The secure transceiver system of claim 7 , wherein said slot is contiguous with said opening and runs from said front face backward.

9. The secure transceiver system of claim 8 , wherein said transceivers are MTRJ transceivers.

10. The secure transceiver system of claim 6 , wherein said transceivers are LC transceivers.

11. The secure transceiver system of claim 6 , wherein said transceivers are MPO transceivers.

12. The secure transceiver system of claim 6 , wherein each plug and receptacle of a mating pair is marked with a matching visual identification different from plugs and receptacles having different first and second geometries, said visual identification being at least one of color, alphanumerical indicia, or symbol.

13. The secure transceiver system of claim 6 , further comprising:

a secondary key extending from the housing of each plug to prevent mating of each plug to a receptacle not having a secondary slot to accommodate said secondary key.

14. In a family of connectors comprising a standard plug and a standard transceiver having

a standard receptacle, a secure connector system for providing discriminating mating among secure and standard plugs and secure transceivers, said secure connector system comprising:

at least a first plug and a second plug, said first plug comprising a first key in a first position, said second plug comprising a second key in a second position, said first and second positions being different, said first and said plugs each comprising a secondary key, said secondary key being in the same relative position on said first and second plugs, said first and second plugs being physically the same except for the position of their respective key;

at least a first transceiver and a second transceiver having first and second receptacles respectively, said first receptacle having a first slot in a first position and a secondary key, said first slot adapted to receive said first key and said secondary slot adapted to receive said secondary key to allow said first plug to mate with said first receptacle to form a mating pair, said first key interfering with a second receptacle to prevent said first plug from mating with said second receptacle, said second receptacle having a second slot in a second position and a secondary key, said secondary slots of said first and second receptacles being in the same relative position, said second slot being adapted to receive said second key and said secondary slot being adapted to receive said secondary key to allow said second plug to mate with said second receptacle to form a mating pair, said second key interfering with said first receptacle to prevent said second plug from mating with said first receptacle;

wherein said standard plug does not have a secondary slot, and said standard receptacle does not have a secondary key; and wherein said first and second keys of said first and second plugs interfere with said standard receptacle to prevent said first and second plugs from mating with said standard receptacle;

wherein said secondary keys of said first and second receptacles interfere with said standard plug to prevent said first and second optical receptacles from mating with said standard plugs.

15. The secure connector system of claim 14 , wherein said transceiver is an MPO transceiver.
