Wont the majority of the trip be over the fibre optic medium - which would require the speed of light (albeit in a glass medium), rather than the speed of electricity?
This also implies that you could materially change that rtt number if you used a faster medium - e.g via air by way of microwave towers.
- pkaye 8y agoYup, speed of light in fiber is roughly 2/3*c.

- Hikikomori 8y agoFunnily enough signal speed in fiber and most copper cablea is the same, 2/3 of the speed of light in vacuum.
