Abstract

A fiber optic connector assembly includes a connector and a carrier. The connector has first and second ends and a terminated fiber. The fiber defines a first end adjacent the first end of the connector and a second end protruding out of the second end of the connector. A carrier having a connector end and an opposite cable end is engaged with the connector. An alignment structure on the carrier includes a first end, a second end, and a throughhole and also a cutaway extending perpendicularly to and communicating with the throughhole. The fiber is positioned within at least a portion of the throughhole with the second end located within the cutaway. A window is within the cutaway over the second end of the fiber for visually inspecting the alignment of the second end of the fiber with an end of another fiber.

First claim

The invention claimed is:

1. An alignment guide for aligning two optical fibers, the alignment guide comprising:
a one-piece base including a first end and a second end and a throughhole extending from the first end to the second end, the base including a cutaway portion extending generally perpendicularly to and communicating with the throughhole; and
a window disposed within the cutaway portion of the base, the window configured for visually inspecting an alignment of the optical fibers;
wherein the base defines conical portions communicating with the throughhole on the first end and the second end to facilitate insertion of the optical fibers into the throughhole.

2. An alignment guide according to claim 1 , wherein the base is generally cylindrical in shape.

3. An alignment guide according to claim 1 , wherein the window is made out of pyrex material.

4. An alignment guide according to claim 1 , wherein the window also includes a cutaway portion configured to be positioned over a contact point of the two optical fibers to be aligned, the cutaway portion of the window configured to provide space for accommodating an index matching gel that is to flow when the two optical fibers are brought in contact with each other.

5. An alignment guide according to claim 1 , further comprising the two optical fibers having been inserted into the base from the first and second ends, respectively, and aligned under the window.

6. An alignment guide according to claim 1 , wherein the cutaway portion of the base is positioned generally halfway along a length of the base.
