How fast does light travel through a fibre optic cable?
I assume this is for a multi-mode cable? In a single-mode cable the light will pretty much follow the cable, without bouncing around much. Although there are

How much latency in optical fibre : r/networking
Hi there, the latency in optical fibre is 5us (micro second) per 1km. It can be easily calculated from the speed of light, divided by the fibre core''s index of refraction (around 1.5 for glass), so 2x 10 8 m/s
