Abstract

Embodiments of the invention include a method for making a partially bonded optical fiber ribbon. The method includes providing a linear array of optical fibers, and applying with an ink jet printing machine a bonding matrix material to at least a portion of at least two adjacent optical fibers. The applied bonding matrix material has a viscosity of approximately 2.0 to approximately 10.0 centipoise (cP) measured at 25 degrees Celsius (° C.). The applied bonding matrix material also has a conductivity of approximately 600 to approximately 1200 millimhos (mmhos). The applied bonding matrix material also has an adhesion of approximately 0.01 to approximately 0.20 Newtons (N). Also, the bonding matrix material is applied to at least a portion of at least two adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon.

First claim

The invention claimed is:

1. A method for making a partially bonded optical fiber ribbon, comprising:
providing a linear array of optical fibers; and
applying with an ink jet printing machine a bonding matrix material to at least a portion of at least two adjacent optical fibers,
wherein the bonding matrix material has a viscosity of approximately 2.0 to approximately 10.0 centipoise (cP) measured at 25 degrees Celsius (° C.),
wherein the bonding matrix material has a conductivity of approximately 600 to approximately 1200 millimhos (mmhos),
wherein the bonding matrix material has an adhesion of approximately 0.01 to approximately 0.20 Newtons (N), and
wherein the bonding matrix material is applied to at least a portion of at least two adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon.

2. The method as recited in claim 1 , wherein the partially bonded optical fiber ribbon is made at a processing speed of up to approximately 500 meters per minute.

3. The method as recited in claim 1 , wherein the partially bonded optical fiber ribbon comprises a linear array of up to 24 optical fibers partially bonded together.

4. The method as recited in claim 1 , wherein the bonding matrix material is a material selected from the group consisting of an ultraviolet curable resin, a thermosetting resin, and a thermoplastic resin.

5. The method as recited in claim 1 , wherein the bonding matrix material applied to at least a portion of at least two adjacent optical fibers is dense enough to cause the resulting partially bonded optical fiber ribbon to be able to lay substantially flat.

6. The method as recited in claim 1 , wherein the bonding matrix material applied to at least a portion of at least two adjacent optical fibers is sparse enough to allow the resulting partially bonded optical fiber ribbon to be rolled into a substantially circular shape.

7. The method as recited in claim 1 , wherein applying the bonding matrix material to at least a portion of at least two adjacent optical fibers further comprises applying filaments or dots of the bonding matrix material across two or more adjacent optical fibers within the linear array of optical fibers along the length of the two or more adjacent optical fibers.

8. A partially bonded optical fiber ribbon, comprising:
a plurality of optical fibers arranged adjacent to one another in a linear array; and
bonding matrix material applied by an ink jet printing machine to at least a portion of at least two adjacent optical fibers,
wherein the bonding matrix material has a viscosity of approximately 2.0 to approximately 10.0 centipoise (cP) measured at 25 degrees Celsius (° C.),
wherein the bonding matrix material has a conductivity of approximately 600 to approximately 1200 millimhos (mmhos),
wherein the bonding matrix material has an adhesion of approximately 0.01 to approximately 0.20 Newtons (N), and
wherein the matrix material is applied to at least a portion of at least two adjacent optical fibers in such a way that the linear array of optical fibers forms a partially bonded optical fiber ribbon.

9. The partially bonded optical fiber ribbon as recited in claim 8 , wherein the partially bonded optical fiber ribbon is made at a processing speed of up to approximately 500 meters per minute.

10. The partially bonded optical fiber ribbon as recited in claim 8 , wherein the partially bonded optical fiber ribbon comprises a linear array of up to 24 optical fibers partially bonded together.

11. The partially bonded optical fiber ribbon as recited in claim 8 , wherein the bonding matrix material is a material selected from the group consisting of an ultraviolet curable resin, a thermosetting resin, and a thermoplastic resin.

12. The partially bonded optical fiber ribbon as recited in claim 8 , wherein the bonding matrix material applied to at least a portion of at least two adjacent optical fibers is dense enough to cause the resulting partially bonded optical fiber ribbon to be able to lay substantially flat.

13. The partially bonded optical fiber ribbon as recited in claim 8 , wherein the bonding matrix material applied to at least a portion of at least two adjacent optical fibers is sparse enough to allow the resulting partially bonded optical fiber ribbon to be rolled into a substantially circular shape.

14. The partially bonded optical fiber ribbon as recited in claim 8 , wherein applying the bonding matrix material to at least a portion of at least two adjacent optical fibers further comprises applying filaments or dots of the bonding matrix material across two or more adjacent optical fibers within the linear array of optical fibers along the length of the two or more adjacent optical fibers.
