Abstract

A system includes a plurality of different types of fiber optic connectors each having at least one stub optical fiber configured to be spliced to at least one cable optical fiber. The system also includes a tool configured to: a) receive and detect the different types of fiber optic connectors; and b) set a threshold value for an acceptable indication of continuity for at least one splice between the at least one stub optical fiber and the at least one cable optical fiber based on which type of the fiber optic connector is received and detected.

First claim

What is claimed is:

1. A device for checking the continuity of at least one splice between optical fibers within a fiber optic connector, wherein there are different possible types of fiber optic connectors with the at least one splice, the device comprising:
a plurality of different connector holders each respectively associated with one of the different types of fiber optic connectors; and
a tool comprising:
a body having a holding area configured to support the different connector holders; and
a printed circuit board coupled to the body, wherein the printed circuit board is configured to:
detect which of the different connector holders is present in the holding area when one of the connector holders is supported by the holding area; and
set a threshold value for an acceptable indication of continuity based on which of the different connector holders is detected.

2. The device according to claim 1 , further comprising:
an optical power generator for delivering light energy to one of the fiber optic connectors when the corresponding connector holder receives the fiber optic connector and is supported by the holding area of the body.

3. The device according to claim 2 , wherein the optical power generator is housed within at least a portion of the body of the tool.

4. The device according to claim 1 , wherein the tool further comprises:
a sensor coupled to the body and configured to detect the light energy delivered by the optical power generator, wherein the printed circuit board is configured to receive a signal from the sensor based on the amount of light detected and compare the signal to the threshold value to check the continuity of the at least one splice.

5. The device according to claim 1 , wherein:
each of the connector holders cooperates with the tool in a different manner when supported by the holding area of the body; and
the printed circuit board is configured to automatically detect which of the different connector holders is present in the holding area based on how the connector holder cooperates with the tool when the connector holder is supported by the holding area of the body.

6. The device according to claim 1 , wherein the tool further comprises:
a plurality of switches coupled to the printed circuit board, wherein the different connector holders actuate different combinations of the switches when supported by the holding area of the body.

7. The device according to claim 6 , wherein the tool further comprises:
a plurality of pins communicating with the holding area, wherein each connector holder is configured to actuate at least one of the switches by depressing at least one of the pins when the connector holder is supported by the holding area of the body.

8. The device according to claim 7 , wherein:
the body includes a plurality of holes in the holding area; and
each pin is received in a corresponding one of the holes.

9. The device according to claim 1 wherein:
each of the different connector holders includes a bottom surface with a different arrangement of one or more first geometric features.

10. The device according to claim 9 , wherein the one or more first geometric features comprises at least one projection on the bottom surface of each of the connector holders.

11. The device according to claim 1 , wherein the tool further comprises:
a user interface configured to receive input from a user about which type of fiber optic connector is present in the holding area, wherein the user interface communicates with the printed circuit board so that the printed circuit board can detect which of the different types of fiber optic connectors is present in the holding area based on the input from the user.

12. A device for checking the continuity of at least one splice between optical fibers within a fiber optic connector, wherein there are different possible types of fiber optic connectors with the at least one splice, the device comprising:
a connector holder associated with one of the different types of fiber optic connectors;
a body having a holding area for supporting the connector holder;
a printed circuit board coupled to the body; and
a plurality of switches coupled to the printed circuit board;
wherein:
each of the switches is capable of being actuated such that there are different possible actuation patterns;
the connector holder is configured to provide one of the different possible actuation patterns when supported by the holding area of the body; and
the printed circuit board is configured to set a threshold value for an acceptable indication of continuity based on the actuation pattern provided by the connector holder.

13. A device for checking the continuity of at least one splice between optical fibers within a fiber optic connector, wherein there are different possible types of fiber optic connectors with the at least one splice, the device comprising:
a body having a holding area configured to support the different possible types of fiber optic connectors;
a printed circuit board coupled to the body;
a plurality of switches coupled to the printed circuit board; and
a plurality of pins communicating with the holding area;
wherein:
each of the pins is configured to be depressed in the holding area to actuate a corresponding one of the switches; and
the printed circuit board is configured to set a threshold value for an acceptable indication of continuity based on which of the switches are actuated.

14. A device for checking the continuity of at least one splice between optical fibers within a fiber optic connector, wherein there are different possible types of fiber optic connectors with the at least one splice, the device comprising:
a body having a holding area configured to support the different possible types of fiber optic connectors; and
a printed circuit board coupled to the body, wherein the printed circuit board is configured to:
detect which of the different types of fiber optic connectors is present in the holding area when one of the fiber optic connectors is supported in the holding area; and
set a threshold value for an acceptable indication of continuity based on which of the different types of fiber optic connectors is detected.

15. The device according to claim 14 , further comprising:
a user interface configured to receive input from a user about which type of fiber optic connector is present in the holding area, wherein the user interface communicates with the printed circuit board so that the printed circuit board can detect which of the different types of fiber optic connectors is present in the holding area based on the input from the user.

16. A system for checking continuity in a fiber optic connector, comprising:
a plurality of different types of fiber optic connectors each including, at least one stub optical fiber configured to be spliced to at least one cable optical fiber; and
a tool having a body and a printed circuit board coupled to the body, wherein the body includes a holding area configured to support the fiber optic connectors, and wherein the printed circuit board is configured to:
