Abstract

An optical receptacle for receiving an optical connector is provided. The optical receptacle may be part of an optical transceiver or an optical adapter. The optical receptacle includes an optical receptacle outer housing wall. An optical receptacle hook opening is formed within the optical receptacle outer housing wall. A receptacle hook is received within the optical receptacle housing, the receptacle hook being configured to retain an optical connector within the optical receptacle. The optical receptacle hook opening is positioned to accommodate the receptacle hook in a flexed position when an optical connector in inserted into the optical receptacle.

Claims

1. A transceiver including an optical receptacle for receiving an optical connector, the transceiver optical receptacle comprising:

a transceiver optical receptacle including an optical receptacle outer housing wall having a thickness;

an optical receptacle hook opening formed within the optical receptacle outer housing wall, the optical receptacle hook opening extending through the entire thickness of the outer housing wall;

a receptacle hook received within the transceiver optical receptacle housing, the receptacle hook configured to retain an optical connector within the transceiver optical receptacle, the receptacle hook comprising a hook arm that is configured to resiliently deflect outwardly to a flexed position as the optical connector is inserted into the transceiver optical receptacle and to resiliently rebound inwardly to retain the optical connector within the transceiver optical receptacle;

wherein the optical receptacle hook opening is positioned so that at least a portion of the hook arm of the receptacle hook is received in the optical receptacle hook opening in the flexed position.

2. The transceiver of claim 1, wherein the receptacle hook is part of an alignment assembly received within the receptacle housing.

3. The transceiver of claim 2, further comprising alignment sleeves received within the alignment assembly.

4. The transceiver of claim 2, wherein the alignment assembly further comprises a receptacle housing hook for attaching the receptacle alignment assembly to the receptacle housing.

5. The transceiver of claim 1, wherein the receptacle housing further comprises a connector alignment slot.

6. An optical adapter for an optical connector, comprising:

an adapter housing including an adapter outer housing wall having a thickness;

an optical receptacle hook opening formed within the adapter outer housing wall, the optical receptacle hook opening extending through the entire thickness of the adapter outer housing wall;

an optical receptacle hook received within the adapter housing, the optical receptacle hook configured to retain an optical connector within the optical adapter, the receptacle hook comprising a hook arm that is configured to resiliently deflect outwardly to a flexed position as the optical connector is inserted into the adapter housing and to resiliently rebound inwardly to retain the optical connector within the adapter;

wherein the receptacle hook opening is positioned so that at least a portion of the hook arm of the receptacle hook is received in the optical receptacle hook opening in the flexed position.

7. The optical adapter of claim 6, wherein the optical receptacle hook is part of an adapter alignment assembly received within the adapter housing.

8. The optical adapter of claim 7, further comprising alignment sleeves received within the adapter alignment assembly.

9. The optical adapter of claim 6, wherein the adapter housing further comprises a panel hook.

10. The optical adapter of claim 6, wherein the adapter housing further comprises an adapter flange.

11. The optical adapter of claim 6, wherein the adapter housing further comprises a flex tab.

12. The optical adapter of claim 7, wherein the adapter alignment assembly further comprises an adapter hook for attaching the adapter alignment assembly to the adapter housing.

13. The optical adapter of claim 6, wherein the adapter housing further comprises a connector alignment slot.
