Abstract
Aspects of the subject disclosure may include, for example, a transmission medium for propagating electromagnetic waves. The transmission medium can include a plurality of cores for selectively guiding an electromagnetic wave of a plurality of electromagnetic waves longitudinally along each core, and a shell surrounding at least a portion of each core for reducing exposure of the electromagnetic wave of each core. Other embodiments are disclosed.
Claims20
A transmission medium, comprising:
- a plurality of cables bundled together in the transmission medium, each cable of the plurality of cables comprising a core;
- a material surrounding at least a portion of each core of the plurality of cables, wherein each core is configured to enable an electromagnetic wave to be bound to the core rather than the material, wherein the electromagnetic wave has an electric field intensity profile that is substantially concentrated within the material, and wherein the material reduces exposure of the electromagnetic wave to an environment;
- and
- an absorbing material coupled to the core of each cable that absorbs a portion of the electromagnetic wave to mitigate cross-talk between the plurality of cables.
A method, comprising:
- receiving, by a transmission medium, a plurality of signals supplied by a plurality of launchers, wherein each signal of the plurality of signals conveys different data, and wherein the transmission medium comprises a plurality of cables, each cable of the plurality of cables comprising a core, wherein each core of the plurality of cables is surrounded at least in part by a covering;
- and
- selectively coupling, by the transmission medium, to each signal of the plurality of signals to generate a guided electromagnetic wave at each core of the plurality of cables, each guided electromagnetic wave having an electric field intensity profile that is substantially concentrated within the covering, wherein the covering of each core reduces exposure of the guided electromagnetic wave propagating at each core, wherein each core has an absorbing material that mitigates cross-talk between the plurality of cables.
A transmission medium, comprising:
- a plurality of cables bundled together in the transmission medium, each cable of the plurality of cables comprising a core;
- a material surrounding at least a portion of each core of the plurality of cables, wherein each core is configured to enable an electromagnetic wave to be bound to the core rather than the material, wherein the electromagnetic wave has an electric field intensity profile that is substantially concentrated within the material, and wherein the material reduces exposure of the electromagnetic wave to an environment;
- and
- an absorbing material that absorbs a portion of the electromagnetic wave to mitigate cross-talk between the plurality of cables.
