> Point2’s E-Tube provides a low-cost, low-loss broadband dielectric waveguide solution that could serve as an advanced alternative to existing electrical and optical interconnects in high-speed, short-reach communication links. It’s 80% lighter and 50% less bulky than copper cables, and could reduce power consumption and the cost of optical cables by 50%, with picosecond latencies that are three orders of magnitude better.

Terahertz quantum resonators currently have a maximum transmission distance of a hundred micrometers:
