This is not a term used in fiber comm. The wave traveling down the fiber has a "mode", and part of it extends beyond the core. Yes, that part is evanescent, but it is part of the mode solution from Maxwell's equations.
All you've done is restated OP's explanation of how a fiber tap works.
- dnautics 13y agoI didn't read any physics in OP's explanation, and you don't necessarily need to melt a fiber optic cable to capture evanescent photons. However, I can see how melting the cable could achieve a splice using evanescent waves.
