Abstract

Aspects of the subject disclosure may include, for example, a transmission medium for propagating electromagnetic waves. The transmission medium can have a first dielectric material for propagating electromagnetic waves guided by the first dielectric material, and a second dielectric material disposed on at least a portion of an outer surface of the first dielectric material for reducing an exposure of the electromagnetic waves to an environment that adversely affects propagation of the electromagnetic waves on the first dielectric material. Other embodiments are disclosed.

First claim

What is claimed is:

1. A transmission medium, comprising:
a non-circular dielectric core, wherein the non-circular dielectric core comprises a first dielectric core that is adaptable for mating to a splicing device, wherein the splicing device comprises a second dielectric core; and
a dielectric material disposed on a first portion of an outer surface of the non-circular dielectric core, wherein the first portion of the non-circular dielectric core is covered by the dielectric material to reduce exposure of electromagnetic waves guided by the non-circular dielectric core to an adverse environment.

2. The transmission medium of claim 1 , wherein the second dielectric core of the splicing device is at least partially aligned with the first dielectric core.

3. The transmission medium of claim 1 , wherein the non-circular dielectric core and the dielectric material have different dielectric constants.

4. The transmission medium of claim 3 , wherein the non-circular dielectric core and the dielectric material enable electromagnetic waves to be guided by the non-circular dielectric core.

5. The transmission medium of claim 1 , wherein a second portion of the non-circular dielectric core is not covered by the dielectric material.

6. The transmission medium of claim 1 , wherein the dielectric material disposed on the first portion of the outer surface of the non-circular dielectric core reduces reflections of the electromagnetic waves guided by the non-circular dielectric core.

7. The transmission medium of claim 1 , wherein the electromagnetic waves have a non-optical frequency range.

8. The transmission medium of claim 1 , wherein the non-circular dielectric core has a first dielectric constant that exceeds a second dielectric constant of the dielectric material.

9. The transmission medium of claim 8 , wherein the first dielectric constant exceeding the second dielectric constant causes the electromagnetic waves to be bound to the non-circular dielectric core.

10. A method, comprising:
receiving, by a transmission medium, signals from a launcher; and
propagating, by the transmission medium, electromagnetic waves guided longitudinally along a non-circular dielectric core of the transmission medium, wherein the electromagnetic waves are generated according to the signals, wherein a first portion of an outer surface of the non-circular dielectric core is covered by a dielectric strip to reduce exposure of the electromagnetic waves to an adverse environment, wherein the dielectric strip comprises non-contiguous sections.

11. The method of claim 10 , wherein the dielectric strip is wrapped around the non-circular dielectric core with varying pitches around a first plurality of portions of the outer surface of the non-circular dielectric core, and wherein a second plurality of portions of the outer surface of the non-circular dielectric core are not covered by the dielectric strip.

12. The method of claim 11 , wherein the varying pitches reduce reflections of the electromagnetic waves.

13. The method of claim 11 , wherein the dielectric strip wrapped around the first plurality of portions of the outer surface of the non-circular dielectric core reduces reflections of the electromagnetic waves.

14. The method of claim 10 , wherein the non-contiguous sections have varying diameters.

15. The method of claim 10 , wherein the non-contiguous sections have varying longitudinal lengths.

16. A cable, comprising:
a non-circular dielectric core, wherein the non-circular dielectric core comprises a first dielectric core that is adaptable for mating to a splicing device, wherein the splicing device comprises a second dielectric core; and
a dielectric cladding surrounding a first portion of the non-circular dielectric core, wherein the first portion of the non-circular dielectric core is covered by the dielectric cladding to reduce exposure of electromagnetic waves guided by the non-circular dielectric core to an adverse environment.

17. The cable of claim 16 , wherein the non-circular dielectric core and the dielectric cladding have different dielectric constants that enable the electromagnetic waves to be bound to the non-circular dielectric core.

18. The cable of claim 16 , wherein the non-circular dielectric core has a first dielectric constant that exceeds a second dielectric constant of the dielectric cladding.

19. The cable of claim 18 , wherein the first dielectric constant exceeding the second dielectric constant causes the electromagnetic waves to be bound to the non-circular dielectric core.

20. The cable of claim 16 , wherein the dielectric cladding surrounding the first portion of the non-circular dielectric core reduces reflections of the electromagnetic waves guided by the non-circular dielectric core.
