Abstract

Various implementations of fiber optic inspection tools with integrated cleaning mechanisms are disclosed. The fiber optic inspection and cleaning tool includes a housing, a cleaning system and an imaging system. The cleaning system includes a pay-off reel, a take-up reel, a spindle and a cleaning tape that travels off the pay-off reel, around the spindle, and onto the take-up reel. The imaging system includes a camera and a light source. The camera, spindle, and cleaning tape are aligned along a visual axis. The pay-off reel, take-up reel, camera and light source are all located within the housing.

First claim

What is claimed is:

1. A fiber optic end-face inspection and cleaning apparatus, comprising:
a housing;
a cleaning system comprising:
a pay-off reel;
a take-up reel;
a spindle; and
a cleaning tape, wherein the cleaning tape travels off the pay-off reel, around the spindle, and onto the take-up reel, the cleaning tape comprising:
a cleaning portion configured to clean an end face of a fiber optic connector; and
a visual portion configured to enable the camera to image the end face of the fiber optic connector; and

an imaging system comprising:
a light source; and
a camera, wherein the camera, the spindle and the tape are in alignment along a direct visual axis; and

wherein the pay-off reel, the take-up reel, camera and light source are located within the housing.

2. The fiber optic end face inspection and cleaning apparatus of claim 1 , further comprising an adapter for receiving an end face of a fiber optic connector.

3. The fiber optic end face inspection and cleaning apparatus of claim 1 , wherein the visual portion is transparent.

4. The fiber optic end face inspection and cleaning apparatus of claim 1 , wherein the visual portion is a cut-out in the cleaning tape.

5. The fiber optic end-face inspection and cleaning apparatus of claim 1 , wherein the cleaning tape includes two layers, wherein at least one of the two layers is a strength substrate.

6. The fiber optic end-face inspection and cleaning apparatus of claim 5 , wherein the strength substrate is mylar.

7. The fiber optic end-face inspection and cleaning apparatus of claim 1 , wherein the tape includes a non-reflective coating.

8. The fiber optic end face inspection and cleaning apparatus of claim 1 , wherein the spindle includes a spindle aperture including tabs.

9. The fiber optic end face inspection and cleaning apparatus of claim 8 , wherein the imaging system further comprises:
at least one lens, wherein the at least one lens directs light from the light source through the spindle aperture.

10. The fiber optic end face inspection and cleaning apparatus of claim 1 , further comprising:
a probe, wherein the spindle is located at a first end of the probe and a second end of the probe is attached within the housing, and the first end of the probe is configured to be insertable into an adapter.

11. The fiber optic end face inspection and cleaning apparatus of claim 10 , wherein the pay-off reel and the take-up reel are comprised of gears.

12. The fiber optic end face inspection and cleaning apparatus of claim 11 , wherein activation of a button on the housing causes the gears to move the cleaning tape.

13. The fiber optic end face inspection and cleaning apparatus of claim 11 , wherein pushing the probe and spindle against the adapter causes the gears to move the cleaning tape.

14. The fiber optic end face inspection and cleaning apparatus of claim 1 , wherein the imaging system additionally includes at least one processor and a lens.

15. The fiber optic end face inspection and cleaning apparatus of claim 1 , wherein the light source is one of an LED or a laser.

16. The fiber optic end face inspection and cleaning apparatus of claim 1 , wherein the tape is formed of multiple layers, including a backing layer and a cleaning layer.

17. A fiber optic end-face inspection and cleaning apparatus, comprising:
a housing;
a cleaning system comprising:
a pay-off reel;
a take-up reel;
a spindle; and
a cleaning tape, wherein the cleaning tape travels off the pay-off reel, around the spindle, and onto the take-up reel; and

an imaging system comprising:
a light source; and
a camera, wherein the camera, the spindle and the tape are in alignment along a direct visual axis; and

an indicator located on top of the housing, wherein the indicator is configured to alert a user to a status of an end face of a fiber optic connector;
wherein the pay-off reel, the take-up reel, camera and light source are located within the housing.

18. The fiber optic end face inspection and cleaning apparatus of claim 17 , wherein the indicator is one of an alarm, LCD screen, or LED.

19. A fiber optic end-face inspection and cleaning apparatus, comprising:
a housing;
a cleaning system comprising:
a pay-off reel;
a take-up reel;
a spindle; and
a cleaning tape, wherein the cleaning tape travels off the pay-off reel, around the spindle, and onto the take-up reel; and

an imaging system comprising:
a light source; and
a camera, wherein the camera, the spindle and the tape are in alignment along a direct visual axis;

a probe including a first end and a second end, wherein the first end of the probe includes the spindle and is configured to be insertable into an adapter, and the second end of the probe is attached within the housing; and
wherein:
the pay-off reel, the take-up reel, camera and light source are located within the housing;
the pay-off reel and the take-up reel are comprised of gears; and
pushing the probe and spindle against the adapter causes the gears to move the cleaning tape.
