Just to prove I never took physics, where are the photons actually going in a long distance undersea cable that makes it impossible to just flash a signal across an ocean sized length of fiber? (As I had assumed was the case.) Is it more a loss of clarity/resolution in terms of wavelength rather than the photons going astray?
- drcoopster 3y agoThink of it as the same as the internal resistance of a conductor. Some of the photons are effectively absorbed by the fiber and turned into heat.
