Abstract

A fixture for retaining an optical connector holder and optical fibers for splicing in an optical fiber stripping machine is disclosed. The fixture enables for two optical fibers of the connector to be appropriately aligned such that they can be simultaneously stripped in a standard optical fiber stripping machine. In one example, the fixture includes a main body extending between a first end and a second, a cavity defined within the main body the cavity, the cavity being for receiving an optical cable holder of an optical fiber connector, a first fiber retention structure for holding the optical fibers extending from the connector holder, and a second fiber retention structure for holding the optical fibers.

First claim

What is claimed is:

1. A fixture for retaining an optical connector holder and optical fibers for splicing in an optical fiber stripping machine, the fixture comprising:
a) a main body extending between a first end and a second end;
b) a cavity defined within the main body, the cavity configured for receiving an optical cable holder of an optical fiber connector; and
c) a first fiber retention structure for holding the optical fibers extending from the connector holder, the first fiber retention structure including a pair of channel structures separated by a central member and being defined by a pair of sidewalls each of which includes an overhang portion extending over one of the channel structures.

2. The fixture of claim 1 , wherein the cavity extends from the first end to the second end of the main body.

3. The fixture of claim 1 , wherein the fixture additionally includes a door operable between an open position and a closed position, wherein when the door is in the open position, the cavity is unobstructed by the door, wherein when the door is in the closed position, a portion of the cavity is covered by the door.

4. The fixture of claim 3 , wherein the fixture includes a magnet for securing the door in the closed position.

5. The fixture of claim 1 , wherein the first fiber retention structure is aligned with a longitudinal axis of the main body.

6. The fixture of claim 1 , further including a second fiber retention structure, wherein the second fiber retention structure includes a pair of channel structures separated by a central member.

7. The fixture of claim 6 , wherein the central member includes a pair of overhang portions extending over the pair of channel structures.

8. A fixture for retaining an optical connector holder and optical fibers for splicing in an optical fiber stripping machine, the fixture comprising:
a) a main body extending between a first end and a second end;
b) a cavity defined within the main body, the cavity configured for receiving an optical cable holder of an optical fiber connector;
c) a first fiber retention structure for holding the optical fibers extending from the connector holder, the first fiber retention structure including a pair of channels separated by a central member; and
d) a second fiber retention structure for holding the optical fibers, the second fiber retention structure being spaced from the first fiber retention structure and including a pair of channels separated by a central member.

9. The fixture of claim 8 , wherein the cavity extends from the first end to the second end of the main body.

10. The fixture of claim 8 , wherein the fixture additionally includes a door operable between an open position and a closed position, wherein when the door is in the open position, the cavity is unobstructed by the door, wherein when the door is in the closed position, a portion of the cavity is covered by the door.

11. The fixture of claim 10 , wherein the fixture includes a magnet for securing the door in the closed position.

12. The fixture of claim 8 , wherein the first and second fiber retention structures are aligned with a longitudinal axis of the main body.

13. The fixture of claim 11 , wherein the first fiber retention structure is defined by a pair of sidewalls, wherein each of the sidewalls includes an overhang portion extending over the channel structures.

14. The fixture of claim 8 , wherein the second fiber retention structure includes a pair of overhang portions extending over the pair of channel structures.

15. A method for stripping optical fibers of an optical connector, the method comprising:
a) providing a fixture including a main body having a cavity and at least one fiber retention structure, the at least one fiber retention structure including a pair of channel structures separated by a central member and being defined by a pair of sidewalls each of which includes an overhang portion extending over one of the channel structures, the main body defining a longitudinal axis;
b) securing an optical cable to a holder of the optical connector such that at least two optical fibers extend beyond the holder;
c) inserting the holder into the cavity such that the at least two optical fibers extend beyond the fixture main body;
d) routing the at least two optical fibers through the at least one fiber retention structure such that a portion of the at least two optical fibers extending beyond the fixture main body are in a generally parallel, spaced apart arrangement, and oriented in a generally parallel relationship to the longitudinal axis of the fixture main body;
e) inserting the fixture into an optical fiber stripping machine; and
f) stripping a portion of the at least two optical fibers.

16. The method of claim 15 , further including the step of closing a door of the fixture to secure the at least two optical fibers within the cavity.

17. The method of claim 15 , wherein the at least two optical fibers includes two optical fibers.
