Abstract

A communications connection system includes an SC fiber optic connector including a storage device having memory configured to store physical layer information. The storage device also includes at least one contact member that is electrically connected to the memory. The communications connection system also includes a fiber optic adapter module having one or more media reading interfaces. Each media reading interface is configured to read physical layer information stored on one of the fiber optic connectors received at the adapter module. Certain types of media reading interfaces extend between an internal passage of the adapter module and an external surface of the adapter module.

Claims

1. A fiber optic connector comprising:

an inner body configured to retain a ferrule that extends longitudinally through the inner body, the inner body defining a channel that extends longitudinally along an exterior surface of the inner body;

an outer body slideably received about the inner body, the outer body defining a cavity recessed in an outer surface of the outer body, at least a portion of the cavity being aligned with the channel defined in the inner body, wherein at least the portion of the cavity slides along the channel when the outer body slides relative to the inner body; and

a storage device positioned in the cavity defined in the outer body, the storage device including memory configured to store physical layer information, the storage device also including at least one contact member that is electrically connected to the memory.

2. The fiber optic connector of claim 1, wherein the portion of the cavity that slides along the channel defines a well protruding inwardly from the outer body.

3. The fiber optic connector of claim 1, wherein the storage device includes a circuit board on which at least one contact member is located, each contact member being electrically coupled to the memory.

4. The fiber optic connector of claim 3, wherein the memory is positioned at a first side of the printed circuit board that faces the cavity and the contact member is positioned at a second side of the printed circuit board that faces away from the cavity, wherein a top of each contact member is flush with the outer surface of the outer body when the storage device is positioned in the cavity.

5. The connectorized optical fiber of claim 1, wherein the memory is an EEPROM chip.

6. The fiber optic connector of claim 5, wherein a portion of the cavity defines a well that protrudes inwardly from an interior of the outer body, the well being sized to accommodate the EEPROM chip.

7. The fiber optic connector of claim 1, wherein the inner body and outer body define an SC connector.

8. The fiber optic connector of claim 1, further comprising an optical fiber having a first end coupled to the ferrule.

9. The fiber optic connector of claim 2, wherein the well has an open bottom facing the channel.

10. The fiber optic connector of claim 1, wherein the portion of the cavity slides in the channel.

11. The fiber optic connector of claim 1, wherein at least a section of the channel extends parallel to the outer surface in which the cavity is recessed.

12. The fiber optic connector of claim 1, wherein the memory is positioned at a first side of a printed circuit board that faces the inner body and the contact member is positioned at a second side of the printed circuit board that faces through an open top of the cavity.

13. The fiber optic connector of claim 1, wherein a top of the cavity has a first area extending across the outer surface of the outer body, and wherein a well is defined at a bottom of the cavity, the well having a second area that is less than the first area.

14. The fiber optic connector of claim 1, wherein the well has an open bottom leading to the channel defined in the inner body.

15. The fiber optic connector of claim 1, wherein the cavity is offset from a center of the outer surface of the outer body.

16. The fiber optic connector of claim 15, wherein sides of the outer surface taper inwardly at a front of the outer body to forward points at the front of the outer body;

and wherein the cavity is offset from the tapering sides of the outer surface so that the cavity is disposed at a position between the forward points.

17. The fiber optic connector of claim 1, wherein the storage device includes a plurality of additional contact members, each contact member extending longitudinally along the outer body.

18. A fiber optic connector comprising:

an inner body configured to retain a ferrule that extends longitudinally through the inner body, the inner body defining a channel that extends longitudinally along an exterior surface of the inner body;

an outer body slideably received about the inner body, the outer body defining a cavity recessed in an outer surface of the outer body, at least a portion of the cavity being aligned with the channel defined in the inner body, wherein at least the portion of the cavity slides along the channel when the outer body slides relative to the inner body; and

a storage device positioned in the cavity defined in the outer body, the storage device including memory positioned entirely in the portion of the cavity that slides along the channel, and the storage device also including at least one contact member that is electrically connected to the memory and that is positioned at an opposite second side of the circuit board to be physically accessible through an open top of the cavity.

19. The fiber optic connector of claim 18, wherein the cavity is laterally offset from a central longitudinal axis of the outer body.
