Study on Circular Waveguide for CAT6e Cable for Future Communication Systems

In wired or wireless telecommunication, the hunger for high data rates is increasing day by day with the increase in the number of users and devices. One possible way to meet the user requirements of the high data rate is to move towards the higher frequency bands, especially the multi-GHz range. Recently it is shown that a data rate in terabits per second can be achieved through the already installed twisted pair cable in the infrastructure by exploiting its higher order guide modes, a waveguide approach. The airgap and dielectric gap between copper cable in the twisted pair cable can be utilized for the propagation of terahertz radiation wirelessly. As CAT6e, twisted pair cable, the airgap is surrounded by copper cables and can be considered as a scaled-down version of a metallic waveguide nearly circular shaped. In this study, a circular metallic waveguide having dimensions similar to the airgap in the CAT6e twisted pair cable is simulated and it is analyzed along with different modes of propagation for its realization for future communication systems.
