Abstract

A fiber optic alignment device includes a first and a second alignment block and a first and a second gel block. A fiber passage extends from a first end to a second end of the fiber optic alignment device. The fiber passage is adapted to receive a first optical fiber through the first end and a second optical fiber through the second end. An intermediate portion of the fiber passage is positioned between the first and the second ends. The intermediate portion is adapted to align the first and the second optical fibers between the first and the second alignment blocks. A first portion of the fiber passage is positioned between the first end and the intermediate portion of the fiber passage. The first portion extends between the first alignment block and the first gel block. A second portion of the fiber passage is positioned between the second end and the intermediate portion of the fiber passage. The second portion extends between the second alignment block and the second gel block. End portions of the first and the second optical fibers may be cleaned when slid between the alignment blocks and the gel blocks. The fiber passage may include an undulating portion.

First claim

What is claimed is:

1. An optical fiber cleaning device for a fiber optic adapter, the optical fiber cleaning device comprising:
a block including a groove;
a gel block; and
a fiber passage extending from a first end to a second end, the fiber passage adapted to receive an optical fiber through the first end of the fiber passage, the fiber passage including a wiping portion positioned between the first end of the fiber passage and the second end of the fiber passage, the wiping portion of the fiber passage extending between the block and the gel block;
wherein the optical fiber is a first optical fiber, wherein the groove extends into an intermediate portion of the fiber passage and at least partially forms a fiber alignment portion of the fiber passage, and wherein the fiber alignment portion of the fiber passage is adapted to align the first optical fiber and a second optical fiber when the first and the second optical fibers are received within the fiber alignment portion.

2. An optical fiber cleaning device for a fiber optic adapter, the optical fiber cleaning device comprising:
a block including a groove;
a gel block; and
a fiber passage extending from a first end to a second end, the fiber passage adapted to receive an optical fiber through the first end of the fiber passage, the fiber passage including a wiping portion positioned between the first end of the fiber passage and the second end of the fiber passage, the wiping portion of the fiber passage extending between the block and the gel block;
wherein the block is a first block;
wherein the optical fiber cleaning device further comprises a second block;
wherein the gel block is a first gel block;
wherein the optical fiber cleaning device further comprises a second gel block;
wherein the optical fiber is a first optical fiber; and
wherein the fiber passage is adapted to receive a second optical fiber through the second end of the fiber passage, the fiber passage including:
an intermediate portion positioned between the first and the second ends of the fiber passage, the intermediate portion adapted to align the first and the second optical fibers between the first and the second blocks;
a first portion positioned between the first end of the fiber passage and the intermediate portion of the fiber passage, the first portion of the fiber passage extending between the first block and the first gel block; and
a second portion positioned between the second end of the fiber passage and the intermediate portion of the fiber passage, the second portion of the fiber passage extending between the second block and the second gel block.

3. The optical fiber cleaning device of claim 2 , wherein the first gel block is adapted to wipe the first optical fiber when the first optical fiber is slid into the fiber passage and wherein the second gel block is adapted to wipe the second optical fiber when the second optical fiber is slid into the fiber passage.

4. An optical fiber cleaning device for a fiber optic adapter, the optical fiber cleaning device comprising:
a block including a groove;
a gel block; and
a fiber passage extending from a first end to a second end, the fiber passage adapted to receive an optical fiber through the first end of the fiber passage, the fiber passage including a wiping portion positioned between the first end of the fiber passage and the second end of the fiber passage, the wiping portion of the fiber passage extending between the block and the gel block;
wherein the gel block fills the groove along at least a portion of the fiber passage when no optical fibers are within the fiber passage.

5. The optical fiber cleaning device of claim 4 , wherein a ridge of the gel block fills the portion of the fiber passage.

6. The optical fiber cleaning device of claim 4 , wherein the gel block seals the first end of the fiber passage.

7. The optical fiber cleaning device of claim 4 , wherein the gel block is adapted to be displaced by an end portion of the optical fiber when the optical fiber is slid within the fiber passage.

8. The optical fiber cleaning device of claim 7 , wherein the gel block is adapted to be displaced by an angled end of the end portion of the optical fiber.

9. The optical fiber cleaning device of claim 4 , wherein the gel block is adapted to wipe the optical fiber when the optical fiber is slid into the fiber passage.

10. The optical fiber cleaning device of claim 4 , wherein the block is a V-block.

11. An optical fiber cleaning device for a fiber optic adapter, the optical fiber cleaning device comprising:
a block member;
a gel member; and
a fiber passage extending from a first end to a second end, the fiber passage adapted to receive an optical fiber through the first end of the fiber passage, the fiber passage including a wiping portion positioned between the first end of the fiber passage and the second end of the fiber passage, the wiping portion of the fiber passage extending between the block member and the gel member;
wherein the gel member is a first gel member, the wiping portion is a first wiping portion, and the optical fiber is a first optical fiber, wherein the optical fiber cleaning device further comprises a second gel member and the fiber passage includes a second wiping portion positioned between the first wiping portion of the fiber passage and the second end of the fiber passage, and wherein the fiber passage is adapted to receive a second optical fiber through the second end of the fiber passage.

12. The optical fiber cleaning device of claim 11 , wherein the gel member is adapted to wipe the optical fiber when the optical fiber is slid into the fiber passage.

13. The optical fiber cleaning device of claim 12 , wherein the block member is a V-block.

14. The optical fiber cleaning device of claim 11 , wherein the first gel member is adapted to wipe the first optical fiber when the first optical fiber is slid into the fiber passage and wherein the second gel member is adapted to wipe the second optical fiber when the second optical fiber is slid into the fiber passage.

15. An optical fiber cleaning device for a fiber optic connection system, the optical fiber cleaning device comprising:
a block member;
a gel member; and
a fiber passage extending from a first end to a second end, the fiber passage adapted to receive an optical fiber through the first end of the fiber passage, the fiber passage including a wiping portion positioned between the first end of the fiber passage and the second end of the fiber passage, the wiping portion of the fiber passage extending between the block member and the gel member;
