Abstract

An optical fiber cable that includes reduced or minimal use of colorant may include a single optical fiber component and a jacket formed around the optical fiber component. The optical fiber component may include at least one optical fiber and a buffer layer formed around the at least one optical fiber. The buffer laying may include one or more first polymeric materials that are not blended or compounded with any colorant, and no colorant may be formed on an outer surface of the buffer layer. Additionally, the jacket may include or more second polymeric materials that are not blended or compounded with any colorant.

Claims (34)

1. A cable, comprising:

a single optical fiber component, the optical fiber component comprising:

at least one optical fiber; and

a buffer layer formed around the at least one optical fiber, the buffer layer comprising one or more first polymeric materials that are not blended or compounded with any colorant, and wherein no colorant is formed on an outer surface of the buffer layer; and

a jacket having a circular cross-sectional shape formed around the optical fiber component, the jacket comprising one or more second polymeric materials that are not blended or compounded with any colorant.

2. The cable of claim 1 , wherein the buffer layer comprises a tight buffer layer.

3. The cable of claim 1 , wherein the buffer layer comprises a loose buffer tube.

4. The cable of claim 3 , wherein a plurality of optical fibers are positioned within the loose buffer tube.

5. The cable of claim 1 , further comprising:

one or more surface variations selectively formed on an outer surface of the buffer layer.

6. The cable of claim 5 , wherein the one or more surface variations comprise at least one of (i) a raised portion or (ii) an indention.

7. The cable of claim 6 , wherein the one or more surface variations comprise at least one of (i) an embossing, (ii) a bump, (iii) a depression, (iv) a protrusion, (v) a dimple, (vi) a ridge, (vii) a groove, (viii) an alphanumeric character, or (ix) a symbol.

8. A cable, comprising:

a single optical fiber component, the optical fiber component comprising:

at least one optical fiber; and

a polymeric buffer layer formed around the at least one optical fiber, the polymeric buffer layer free of colorant; and

a jacket having a circular cross-sectional shape formed around the optical fiber component, the jacket comprising one or more polymeric materials that are not blended or compounded with any colorant.

9. The cable of claim 8 , wherein the polymeric buffer layer comprises a tight buffer layer.

10. The cable of claim 8 , wherein the polymeric buffer layer comprises a loose buffer tube.

11. The cable of claim 10 , wherein a plurality of optical fibers are positioned within the loose buffer tube.

12. The cable of claim 8 , further comprising:

one or more surface variations selectively formed on an outer surface of the polymeric buffer layer.

13. The cable of claim 12 , wherein the one or more surface variations comprise at least one of (i) a raised portion or (ii) an indention.

14. The cable of claim 12 , wherein the one or more surface variations comprise at least one of (i) an embossing, (ii) a bump, (iii) a depression, (iv) a protrusion, (v) a dimple, (vi) a ridge, (vii) a groove, (viii) an alphanumeric character, or (ix) a symbol.

15. A cable, comprising:

one or more optical fibers;

a single buffer layer formed around the one or more optical fibers, the single buffer layer comprising one or more first polymeric materials that are not blended or compounded with any colorant, and wherein no colorant is formed on an outer surface of the buffer layer; and

an outer jacket having a circular cross-sectional shape formed around the single buffer layer, wherein no buffer layers other than the single buffer layer are positioned within the outer jacket, the outer jacket comprising one or more second polymeric materials that are not blended or compounded with any colorant.

16. The cable of claim 15 , wherein the single buffer layer comprises a tight buffer layer.

17. The cable of claim 15 , wherein the single buffer layer comprises a loose buffer tube.

18. The cable of claim 17 , wherein the one or more optical fibers comprises a plurality of optical fibers positioned within the loose buffer tube.

19. The cable of claim 17 , further comprising:

one or more surface variations selectively formed on an outer surface of the single buffer layer.

20. The cable of claim 19 , wherein the one or more surface variations comprise at least one of (i) a raised portion or (ii) an indention.
