Abstract

A method of forming an optical fiber connector is provided. The optical connector includes a body having a passage with a first section extending inwardly from a first face of the body, a second section extending inwardly from a second face from the body, and a transition section located between the first and second sections. The first section of the passage has a first width and the second section of the passage has a second width that is less than the first width. The method comprises loading an adhesive composition into the passage and storing the adhesive composition for at least one day without coupling the optical connector to an optical fiber. The adhesive composition is a meltable, substantially solid material maintained the first passage section, transition section, or both the second passage section and transition section.

First claim

What is claimed is:

1. A method of forming an optical connector that includes a body having a first face and a second face, wherein the optical connector also includes a passage defined in the body and extending between a first opening formed in the first face and a second opening formed in the second face, and wherein the passage includes a first passage section extending inwardly from the first face and having a first width, a second passage section extending inwardly from the second face and having a second width that is less than the first width, and a transition section located between the first passage section and the second passage section, the method comprising:
loading an adhesive composition into the passage; and
storing the adhesive composition in the passage for at least one day without coupling the optical connector to an optical fiber, wherein the adhesive composition is a meltable, substantially solid material maintained the first passage section, transition section, or both the second passage section and transition section.

2. The method of claim 1 , further comprising:
coupling the optical connector to an optical fiber after storing the adhesive composition in the passage for at least one day.

3. The method of claim 1 , wherein coupling the optical connector to the optical fiber comprises:
heating the adhesive composition to cause the adhesive composition to melt;
inserting the optical fiber through the passage and the melted adhesive composition, wherein the optical fiber pulls the melted adhesive composition into the second passage section; and
cooling the body to solidify the adhesive composition and thereby secure the optical fiber in the second passage section.

4. The method of claim 3 , wherein heating the adhesive composition comprises heating a portion of the body that includes the adhesive composition above 290° C. while keeping the first face of the body below 250° C.

5. The method of claim 3 , wherein heating the adhesive composition comprises heating a portion of the body that includes the adhesive composition above 350° C. while keeping the first face of the body below 250° C.

6. The method of claim 3 , wherein air occupies at least a portion the first passage section during the heating step, thereby acting as a buffer to heat transfer along the body.

7. The method of claim 3 , wherein cooling the body comprises passively cooling by allowing the body and the adhesive composition to return to a temperature at which the adhesive composition solidifies.

8. The method of claim 3 , wherein cooling the body comprises actively cooling by blowing air.

9. The method of claim 3 , wherein the adhesive composition solidifies in less than 30 seconds after the heating step.

10. The method of claim 1 , wherein loading the adhesive composition comprises locating the adhesive composition within the transition section so that the adhesive composition blocks an entrance into the second passage section from the transition section.

11. The method of claim 1 , wherein loading the adhesive composition comprises locating at least 95% of the adhesive composition between an axial midpoint of the body and the second passage section.

12. The method of claim 1 , wherein loading the adhesive composition comprises locating at least 50% of the adhesive composition within the transition section.

13. The method of claim 1 , wherein the adhesive composition comprises a solid powdered adhesive composition during the loading and storing steps.

14. The method of claim 1 , further comprising extruding or injection molding the adhesive composition to form an adhesive plug.

15. The method of claim 1 , further comprising:
coupling the adhesive composition to an inner surface of the body.

16. The method of claim 15 , wherein coupling the adhesive composition to the interior surface of the body comprises solidifying the adhesive composition within the transition passage section after loading the adhesive composition.

17. A method of forming an optical connector that includes a body having a first face and a second face, wherein the optical connector also includes a passage defined in the body and extending between a first opening formed in the first face and a second opening formed in the second face, and wherein the passage includes a first passage section extending inwardly from the first face and having a first width, a second passage section extending inwardly from the second face and having a second width that is less than the first width, and a transition section located between the first passage section and the second passage section, the method comprising:
loading an adhesive composition into the passage, wherein the adhesive composition is loaded into the passage at a first facility;
storing the adhesive composition in the passage for at least one day without coupling the optical connector to an optical fiber, wherein the adhesive composition is a meltable, substantially solid material maintained the first passage section, transition section, or both the second passage section and transition section;
shipping the body to a second facility after loading the adhesive composition into the passage; and
coupling the optical connector to an optical fiber at the second facility.

18. A method of forming an optical connector that includes a body having a first face and a second face, wherein the optical connector also includes a passage defined in the body and extending between a first opening formed in the first face and a second opening formed in the second face, and wherein the passage includes a first passage section extending inwardly from the first face and having a first width, a second passage section extending inwardly from the second face and having a second width that is less than the first width, and a transition section located between the first passage section and the second passage section, the method comprising:
loading an adhesive composition into the passage;
coupling the adhesive composition to an inner surface of the body, wherein the adhesive composition comprises a solid powdered adhesive composition during the loading step, and further wherein coupling the adhesive composition to the interior surface of the body comprises packing the adhesive composition into the transition section via compression; and
storing the adhesive composition in the passage for at least one day without coupling the optical connector to an optical fiber, wherein the adhesive composition is a meltable, substantially solid material maintained the first passage section, transition section, or both the second passage section and transition section.

19. A method of forming an optical connector that includes a body having a first face and a second face, wherein the optical connector also includes a passage defined in the body and extending between a first opening formed in the first face and a second opening formed in the second face, wherein the passage includes a first passage section that is a cylindrical bore extending inwardly from the first face and having a first diameter, a second passage section that is a cylindrical extending inwardly from the second face and having a second diameter that is less than half the first diameter, and a transition section located between the first passage section and the second passage section, and wherein an axial length of the second passage section is greater than an axial length of the transition section and less than a third of the axial length of the body, the method comprising:
loading an adhesive material int
