>This advantage only increases over time, as tighter cables provide higher bandwidth – the 2012 generation of cables drop

Are they able to achieve a direct, straight-line path between the two endpoints over thousands of miles?
- XorNot 4y agoYou never get that with fiber optics to start with - total internal reflection implies the light is traveling a fairly complicated geometry anyway. To do a straight line path it wouldn't be a fiber cable, it would be a tube which you'd have to pressurize and then do a fair bit of work to try and keep from flexing out of alignment (although 3 reflections as opposed to hundreds of thousands probably helps).
