Abstract

Methods and apparatuses for providing secure fiber optic connections are disclosed. In one embodiment, a locking apparatus comprising a locking plate to secure fiber optic connections is disclosed. The locking plate is configured to be attached to a fiber optic adapter panel and adjustably positioned to a selected position such that when a fiber optic connector on the end of a fiber optic cable is connected to a fiber optic adapter on the fiber optic adapter panel, the fiber optic cable is allowed to pass through a cut-out area of the locking plate but a finger portion of the locking plate does not allow the fiber optic connector to pass through the cut-out area. A lock disposed on the locking plate is configured to keep the locking plate in the selected position. The locking apparatus may also be used to securely store unused or unconnected ports of an optical splitter in a separate enclosure, such as a parking lot compartment.

Claims

1. An apparatus for securing fiber optic connections comprising:

a locking plate comprising at least one cut-out area and at least one finger portion; and

wherein the locking plate is configured to be adjustably positioned in a selected position such that when a fiber optic connector on an end of a fiber optic cable is connected to at least one fiber optic adapter, the fiber optic cable is allowed to pass through the at least one cut-out area of the locking plate but the at least one finger portion of the locking plate does not allow the fiber optic connector to pass through the at least one cut-out area of the locking plate; and

a lock disposed on the locking plate configured to keep the locking plate in the selected position after the locking plate has been adjustably positioned in the selected position.

2. The apparatus of claim 1, wherein the locking plate is further configured to be attached to a fiber optic adapter panel having a plurality of fiber optic adapters disposed thereon, wherein at least one fiber optic adapter of the plurality of fiber optic adapters is configured to be connected to the fiber optic connector disposed on the end of the fiber optic cable.

3. The apparatus of claim 2, wherein the locking plate is hingedly attached to the fiber optic adapter panel such that the locking plate is configured to be movable to the selected position.

4. The apparatus of claim 2, wherein the locking plate is hingedly attached to an extension plate that is affixed to the fiber optic adapter panel at an angle at or about ninety (90) degrees.

5. The apparatus of claim 2, wherein the fiber optic adapter panel is a duplex fiber optic adapter panel and one or more of the plurality of fiber optic adapters are configured to be connected to one or more respective fiber optic connectors disposed on an end of one or more respective fiber optic cables;

and

wherein the one or more respective fiber optic cables are allowed to pass through the cut-out area of the locking plate but the at least one finger portion of the locking plate does not allow the one or more respective fiber optic connectors to pass through the cut-out area of the locking plate.

6. The apparatus of claim 5, wherein when the locking plate is in the selected position, additional fiber optic connectors other than the one or more respective fiber optic connectors cannot be connected to any one of the plurality of fiber optic adapters.

7. The apparatus of claim 2, wherein the fiber optic adapter panel further comprises an adapter plunger configured to be selectively actuated to allow the fiber optic adapter panel to be removed from a housing in which the fiber optic adapter panel is located.

8. The apparatus of claim 7, wherein the locking plate further comprises an end plate that covers the adapter plunger to prevent access to the adapter plunger in order to prevent removal of the fiber optic adapter panel from the housing.

9. The apparatus of claim 2, wherein the fiber optic adapter panel is part of a parking lot compartment for parking fiber optic cables.

10. The apparatus of claim 1, wherein when the locking plate is in the selected position, additional fiber optic connectors are prevented from being connected to any one of the plurality of fiber optic adapters.

11. The apparatus of claim 1, wherein the lock has a unique key.

12. The apparatus of claim 1, wherein the fiber optic connector is of a type of fiber optic connector selected from a group comprising:

LC connectors, SC connectors, ST connectors, MTP connectors, FC connectors, MU connectors, and MTRJ connectors.

13. The apparatus of claim 1, wherein the at least one fiber optic adapter is located on a wall outlet box, and wherein the locking plate is attached to the wall outlet box.

14. A method for securing fiber optic connections, comprising:

providing a locking plate comprising at least one cut-out area and at least one finger portion;

positioning the locking plate in a selected position such that when a fiber optic connector on an end of a fiber optic cable is connected to at least one fiber optic adapter, the fiber optic cable is allowed to pass through the at least one cut-out area of the locking plate but the fiber optic connector is not allowed to pass through the at least one cut-out area of the locking plate; and

providing a lock disposed on the locking plate, the lock configured to keep the locking place in the selected position.

15. The method of claim 14, wherein the locking plate is further configured to be attached to a fiber optic adapter panel having the at least one fiber optic adapter disposed thereon.

16. The method of claim 14, further comprising connecting the at least one fiber optic adapter to the fiber optic connector prior to positioning the locking plate in the selected position.

17. The method of claim 15, wherein the fiber optic adapter panel is part of at least one parking lot compartment, the method further comprising:

parking one or more unused or unconnected optical fibers split by an optical splitter in one or more parking lot adapters in the at least one parking lot compartment by connecting the one or more parking lot adapters to one or more respective fiber optic connectors disposed on an end of one or more respective fiber optic cables comprising one or more unused or unconnected optical fibers.

18. The method of claim 16, wherein the parking is done prior to positioning the locking plate in the selected position.

19. The method of claim 14, further comprising electronically or optically monitoring the lock.
