Abstract

An optical plug having an anti-snag guide to prevent the plug from being caught on corners and edges when an attached cable is being pulled around corners and edges during installation and removal of the optical plug. The optical plug includes a unique arrangement of different width apertures corresponding to a removal tool having corresponding different width prongs to be received by the apertures to release the optical plug from an optical receptacle.

Claims (51)

1. An optical fiber connector, comprising:

a body having a front and a back, the body extending in a longitudinal direction between the front and the back of the body;

a back plate connected to the back of the body and extending beyond an outer surface of the body and perpendicular to the longitudinal direction of the body, and the back plate including a plurality of apertures having similar configurations;

said back plate further including a unique aperture having a different configuration from the plurality of apertures on the back plate to form a keyed configuration, thereby requiring a removal tool having prongs matching the keyed configuration to pass through the plurality of apertures and the unique aperture on the back plate;

a boot connected to the back of the body for surrounding an optical fiber cable; and

an anti-snag guide having a guide plate connected to the back plate, wherein the anti-snag guide includes a first ramp passing between an outer surface of the boot and an outer edge of the guide plate.

2. The optical fiber connector of claim 1 , further comprising:

a second ramp passing between an outer surface of the boot and the outer edge of the guide plate.

3. The optical fiber connector of claim 1 , wherein the guide plate includes apertures aligned and corresponding in shape and size to at least one of the plurality of apertures and the unique aperture on the back plate.

4. The optical fiber connector of claim 1 , further comprising:

a removal tool have a plurality of prongs having a cross-sectional configuration corresponding to the plurality of apertures on the back plate;

a unique prong on the removal tool having a different cross-sectional configuration than the plurality of prongs but corresponding to the unique aperture; and

said plurality of prongs are to be inserted into the plurality of apertures and the unique prong is to be inserted into the unique aperture to release the optical fiber connector from an optical receptacle.

5. The optical fiber connector of claim 4 , further comprising:

a clip on a front of the removal tool for grabbing an edge of the back plate in order to assist in removing the optical fiber connector from an optical receptacle.

6. The optical fiber connector of claim 4 , further comprising:

an arm extension on a front of the removal tool; and

a foot extension on a front of the removal tool extending beyond the arm extension and functioning as a key to properly position the removal tool when contacting the optical fiber connector.

7. The optical fiber connector of claim 1 , wherein the guide plate of the anti-snag guide includes apertures for receiving prongs of a removal tool.

8. The optical fiber connector of claim 1 , further comprising:

a removal tool have a plurality of prongs having a cross-sectional configuration corresponding to the plurality of apertures on the back of the optical fiber connector;

a unique prong on the removal tool having a different cross-sectional configuration than the plurality of prongs but corresponding to the unique aperture;

said plurality of prongs are to be inserted into the plurality of apertures and the unique prong is to be inserted into the unique aperture to release the optical fiber connector from an optical receptacle;

an arm extension on a front of the removal tool for contacting the guide plate; and

a foot extension on a front of the removal tool extending beyond the arm extension for contacting the back plate; and

wherein the arm extension and the foot extension function as a key to properly position the removal tool when contacting the optical fiber connector.

9. The optical fiber connector of claim 1 , wherein the guide plate includes at least one aperture aligned and corresponding in shape and size to one of the plurality of apertures.

10. The optical fiber connector of claim 1 , wherein the guide plate includes an aperture aligned and corresponding in shape and size to the unique aperture.

11. The optical fiber connector of claim 1 , wherein an external surface of the guide plate is a first color.

12. The optical fiber connector of claim 1 , wherein an external surface of the guide plate is a second color.

13. The optical fiber of claim 4 , wherein an external surface of the removal tool includes a color similar to a color of an external surface of the guide plate.

14. An optical fiber connector, comprising:

a body having a front and a back, the body extending in a longitudinal direction between the front and the back of the body;

a back plate connected to the back of the body and extending perpendicular to the longitudinal direction of the body, and the back plate including at least one aperture having a first configuration and at least one aperture having a second configuration to form a keyed configuration, thereby requiring a removal tool having prongs matching the keyed configuration to pass through the at least one aperture having a first configuration and the at least one aperture having a second configuration on the back plate;

a boot connected to the back of the body for surrounding an optical fiber cable; and

an anti-snag guide having a guide plate connected to the back plate, wherein the anti-snag guide includes a ramp passing between an outer surface of the boot and an outer edge of the guide plate.

15. The optical fiber connector of claim 14 , further comprising:

a removal tool have a plurality of prongs having a cross-sectional configuration corresponding to the at least one aperture having a first configuration and the at least one aperture having a second configuration; and

said plurality of prongs are to be inserted into the at least one aperture having a first configuration and the at least one aperture having a second configuration to release the optical fiber connector from an optical receptacle.

16. The optical fiber connector of claim 14 , wherein the guide plate includes at least one aperture having the first configuration and at least one aperture having the second configuration, each aligned and corresponding respectively to shape and size of the at least one aperture of the first configuration and the at least one aperture of the second configuration in the back plate.

17. The optical fiber of claim 15 , wherein an external surface of the removal tool includes a color similar to a color of an external surface of the guide plate.

18. An optical fiber connector, comprising:

a body having a front and a back, the body extending in a longitudinal direction between the front and the back of the body;

a back plate connected to the back of the body and extending perpendicular to the longitudinal direction of the body, and the back plate including at least one aperture having a first configuration and at least one aperture having a second configuration to form a keyed configuration, thereby requiring a removal tool having prongs matching the keyed configuration to pass through the at least one aperture having a first configuration and at least one aperture having a second configuration on the back plate;

a bung located within an aperture in the back plate for receiving an optical fiber cable; and

an anti-snag guide having a guide plate connected to the back plate, wherein the anti-snag guide includes a ramp passing between an outer surface of the bung and an outer edge of the guide plate.

19. The optical fiber connector of claim 18 , wherein the guide plate includes at least one aperture having the first configuration and at least one aperture having the second configuration, each aligned and corresponding respectively to shape and size of the at least one aperture of the first configuration and the at least one aperture of the second configuration in the back plate.

20. The optical fiber connector of claim 18 , further comprising:

a removal tool have a plurality of prongs having a cross-sectional configuration corresponding to the at least one aperture having a first configuration and the at least one aperture having a second configuration; and

said plurality of prongs are to be inserted into the at least one aperture having a first configuration and the at least one aperture having a second configuration to release the optical fiber connector from an optical receptacle; and
