Abstract

A device to strip the external coating layer off of a coated optical fiber is provided. The optical fiber coating removal device includes a one piece molded body having a first body portion connected to a second body portion by a flexible region and a blade secured in one of the first body portion and the second body portion wherein the blade includes a U-shaped slot having cutting edges on the inside of the slot, wherein the flexible portion allows the first and second body portions to move between an open state and a closed state for stripping an optical fiber.

Claims (19)

1. An optical fiber coating removal device, comprising:

a one piece molded body having a first body portion connected to a second body portion by a flexible portion,

a first metal blade secured in the first body portion, wherein the first blade includes a first U-shaped slot having cutting edges on the inside of the slot, and

an open fiber guide channel formed in the second body portion, wherein the fiber guide channel has a first channel wall having a blade access slot extending therethrough and a second channel wall disposed opposite the first channel wall, wherein the first and second channel walls are sloped to create a substantially V-shaped fiber guide channel the facilitates placement of the coated optical fiber in the optical fiber coating removal device,

wherein the blade is oriented perpendicular the guide channel when the blade extends through the blade access slot, and

wherein the flexible portion allows the first and second body portions to move between an open state and a closed state for stripping an optical fiber.

2. The device of claim 1 , further comprising a blade counter sink slot formed in the second channel wall and aligned with the fiber access slot.

3. The device of claim 1 , further comprising strip length indicia formed in the second body portion adjacent to the fiber guide channel to aid in removing the appropriate amount of coating material from a terminal end of an optical fiber.

4. The device of claim 1 , wherein the first blade further comprises a second U-shaped slot having cutting edges on the inside of the slot, wherein the first U-shaped slot is characterized by a first width and the second U-shaped slot is characterized by a second width.

5. The device of claim 1 , wherein the cutting edges of the first blade are beveled from a first thickness to a second thickness.

6. The device of claim 1 , wherein the flexible portion is a living hinge.

7. The device of claim 1 , wherein the first metal blade is created by a stamping process and is press fit into an opening in the first body portion.

8. The device of claim 1 , wherein the first metal blade is created by a stamping process and is insert molded into the first body portion when the body of the optical fiber coating removal tool is formed.

9. An optical fiber coating removal device incorporated into a base of an optical fiber cleaving device, comprising:

a one piece molded body integrally molded with the base of the optical fiber cleaving device, wherein the one piece molded body includes a first body portion connected to a second body portion which is a section of the base of the optical fiber cleaving device and wherein the first body portion is connected to the second body portion by a flexible region allowing the first body portion to move relative to the second body portion between an open state and a closed state for stripping an external protective coating from a coated optical fiber;

a fiber guide channel formed in the second body portion, wherein the fiber guide channel has a first channel wall having a blade access slot extending therethrough and a second channel wall disposed opposite the first channel wall, wherein the first and second channel walls are sloped to create a substantially V-shaped fiber guide channel the facilitates placement of the coated optical fiber in the optical fiber coating removal device; and

at least a first metal blade secured in the first body portion when the blade extends through the blade access slot.

10. The device of claim 9 , further comprising a blade counter sink slot formed in the second channel wall and aligned with the fiber access slot.

11. The device of claim 9 , further comprising strip length indicia formed on the surface of the base of the optical cleaver to aid in removing the appropriate amount of coating material from a terminal end of an optical fiber.
