Abstract

A network comprising: (a) a plurality of different receptacles for facilitating a connection to different information networks requiring different access authorization, each different receptacle optically or electrically coupled to one and only one different information network, each different receptacle having an inner surface with a unique first geometry; and (b) a plurality of different plugs for optically or electrically coupling with the different receptacles, each different plug having a unique second geometry, each unique first geometry corresponds to one, and only one, unique second geometry of a plug such that plugs and receptacles having corresponding unique first and second geometries are mating pairs.

Claims

1. A network comprising:

a plurality of different receptacles for facilitating a connection to different information networks requiring different access authorization, each different receptacle 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 for optically or electrically coupling with said different receptacles, 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;

wherein each mating pair is marked with a matching visual identification different from said plugs and receptacles having different first and second geometries, said visual identification being at least one of color, alphanumerical, or symbol; and

wherein the network further comprising said different information networks, each different information network is on a different optical or electrical circuit and each different receptacle is optically or electrically connected to one and only one different circuit.

2. The network of claim 1, wherein the number of mating pairs is four.

3. The network of claim 1, wherein said first and second geometries include a keying mechanism to render said different receptacles and plugs unique.

4. The network of claim 3, wherein said keying mechanism is at least one of a key and slot relationship between the plug and receptacle, said receptacle dimensioned to receive only certain sized or shaped plugs, or a magnetic signature for attracting mating pairs and repelling non-mating pairs.

5. The network of claim 4, wherein said keying mechanism is a key and slot mechanism.

6. The network of claim 5, wherein said first geometry includes said key, and said second geometry includes said slot.

7. The network of claim 6, 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.

8. The network of claim 5, wherein said first geometry includes said slot, and said second geometry includes said key.

9. The network of claim 1, wherein said plugs and receptacles are optical and said network is optical.

10. A network comprising:

a plurality of different circuits, each circuit having access to information requiring different access authorization;

a plurality of receptacles, each receptacle having an inner surface with a first geometry, said first geometry comprising at least a slot, a certain number of receptacles having different first geometries in which the slots are in different positions said each receptacle having said different first geometry corresponds to one and only one different circuit; and

a plurality of plugs, said each plug having said second geometry, said second geometry comprising at least a key in a certain position, said certain number of plugs having different second geometries in which the keys are in different positions, each plug having a different second geometry corresponds to one and only one different circuit, each different said first geometry corresponding to one and only one second geometry such that the plugs and receptacles of corresponding first and second geometries are mating pairs;

wherein the mating pair is marked with a matching visual identification different from said plug and receptacle having different first and second geometries, said visual identification being at least one of color, alphanumerical, or symbol.

11. The network of claim 10, wherein the connector type is push-pull connectors.

12. The network of claim 10, wherein the connector type is an MT type connector.

13. The network of claim 10, further comprising a universal plug having no key to interfere with said first and second receptacles.

14. The network of claim 10, wherein said plugs and receptacles are optical and said network is optical.

15. A method of limiting access to information networks within a network, said method comprising:

providing a network comprising a plurality of different receptacles for facilitating a connection to different information networks requiring different access authorization, each different receptacle 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

providing a first user authorized to access a first information network of said different information networks with a first plug of a plurality of different plugs for coupling with said different receptacles, each different plug having a unique second geometry, each unique first geometry corresponds to one, and only one, unique second geometry of a plug such that plugs and receptacles having corresponding unique first and second geometries are mating pairs, said first plug forming a mating pair with a different fiber receptacle optically or electrically coupled to said first information networks; and

providing a second user authorized to access a second information network of said different information networks with a second plug of said plurality of different plugs, said first and second information networks being different, said second plug forming a mating pair with a different fiber receptacle optically or electrically coupled to said first information networks;

wherein each mating pair is marked with matching visual identification which is unique among the different mating pairs, said visual identification being at least one of color, alphanumerical, or symbol.

16. The method of claim 15, wherein said plugs and receptacles are optical and said network is optical.
