Waveguides with active or passive repeaters for range extension

A mm-wave waveguide comprising:

• a dielectric waveguide;
• a conductive layer covering the dielectric waveguide;
• and
• a passive repeater integrated within the dielectric waveguide, wherein the passive repeater includes a dispersion compensating material, and wherein the dispersion compensating material produces a dispersion response in a signal that is substantially opposite to a dispersion response produced when the signal is propagated along the dielectric waveguide.

A computing system, comprising:

• a server, comprising:
• a printed circuit board (PCB);
• a central processing unit (CPU) die packaged on a CPU packaging substrate, wherein the CPU packaging substrate is electrically coupled to the PCB;
• and
• a mm-wave engine packaged on a mm-wave engine packaging substrate, wherein the mm-wave engine packaging substrate is coupled to the CPU packaging substrate with a predefined digital interface;
• and
• a mm-wave waveguide communicatively coupled to the mm-wave engine, wherein the mm-wave waveguide, comprises:
• a first dielectric waveguide;
• a second dielectric waveguide;
• a conductive layer covering the first dielectric waveguide and the second dielectric waveguide;
• and
• a repeater communicatively coupled between the first dielectric waveguide and the second dielectric waveguide, wherein the repeater is a passive repeater or an active repeater, and wherein a total length of the mm-wave waveguide is greater than 5 meters.
