Consumes 1/3 the power of optical, but costs 1/3 more than optical

Start-up plans to attempt using a different band of the EM spectrum for a communications medium, news at 11?

Lasers are already terahertz frequency (~200ish Thz), just higher than the radio portion (~30 Thz).

They are reinventing physical multiplexing with waveguide…

One of their cables has 8 waveguides inside. Sounds like mpo based QSFP.
