MIT Cable-Theory of Operation??

I am interested in the operating principle if any behind the MIT design ( other than to make a huge profit).I have read the "reflected energy" and "signal transfer" jargon. Have any engineers ever taken these apart or run a swept tone through the cable to see what it does to a waveform? Not trying to poo poo the cable or empirical results, just wondered why there seems to be so much secrecy behind the technology and lack of info on the technology behind the design.Dont those little boxes pique anyones curiosity? I know as with any product these have their fans and detractors but wanted to hear from the test bench side.
