Abstract

The present invention provides multi-optoelectronic assemblies in which a plurality of multi-receiver cages in which are mounted multi-optical receptacle assemblies associated with a plurality of transceivers are mounted on a printed wire assembly. The multi-optical receptacle assemblies includes a plurality of receptacles having shared walls, unitary walls or no walls. The multi-optoelectronic assemblies are compatible with multi-fiber assemblies.

Claims

1. A multi-optical receptacle assembly comprising at least two adjacent optical receptacles of a multi-transceiver assembly and a shared wall extending in a distal and/or proximal direction between said adjacent optical receptacles, wherein said optical receptacles each include at least a part of said shared wall and wherein each of said optical receptacles includes two or more channels for two or more respective optical fibers of two or more respective optical connectors to extend into when said two or more respective optical connectors are inserted into each of said optical receptacles.

2. The multi-optical receptacle assembly of claim 1, wherein said multi-optical receptacle assembly comprises two optical receptacles.

3. The multi-optical receptacle assembly of claim 1, wherein said multi-optical receptacle assembly comprises four optical receptacles.

4. The multi-optical receptacle assembly of claim 1, wherein said multi-optical receptacle assembly comprises more than four optical receptacles.

5. The multi-optical receptacle assembly of claim 1, wherein said shared wall has a thickness of 0.001 inch to 0.15 inch.

6. The multi-optical receptacle assembly of claim 5, wherein said shared wall comprises a unitary shared wall.

7. The multi-optical receptacle assembly of claim 1, wherein said shared wall comprises a unitary shared wall.

8. The multi-optical receptacle assembly of claim 1, wherein said multi-transceiver assembly comprises at least two transceivers having said shared wall between adjacent transceivers of said at least two transceivers.

9. The multi-optical receptacle assembly of claim 8, wherein said multi-transceiver assembly comprises two transceivers.

10. The multi-optical receptacle assembly of claim 8, wherein said multi-transceiver assembly comprises four transceivers.

11. The multi-optical receptacle assembly of claim 8, wherein said multi-transceiver assembly comprises more than four transceivers.

12. The multi-optical receptacle assembly of claim 8, wherein said shared wall has a thickness of 0.001 inch to 0.1 inch.

13. A multi-optical receptacle assembly comprising at least two adjacent optical receptacles and a shared wall extending in a distal and/or a proximal direction between said adjacent optical receptacles, wherein said shared wall comprises a unitary shared wall, wherein said optical receptacles each include at least a part of said shared wall and wherein each of said optical receptacles includes two or more channels for two or more respective optical fibers of two or more respective optical connectors to extend into when said two or more respective optical connectors are inserted into each of said optical receptacles.

14. A multi-optical receptacle assembly comprising:

at least two optical receptacles;

a connecting means that connects together said at least two optical receptacles; and

a mounting means for mounting said multi-optical receptacle assembly in a housing, wherein said multi-optical receptacle assembly has a unibody construction and wherein each of said optical receptacles includes two or more channels for two or more respective optical fibers of two or more respective optical connectors to extend into when said two or more respective optical connectors are inserted into each of said optical receptacles.

15. The multi-optical receptacle assembly of claim 14, wherein said at least two optical receptacles comprise two optical receptacles.

16. The multi-optical receptacle assembly of claim 14, wherein said at least two optical receptacles comprise four optical receptacles.

17. The multi-optical receptacle assembly of claim 14, wherein said at least two optical receptacles comprise more than four optical receptacles.
