What is the thickness of a single mode fibre optic?
- 50 micrometres
- 5 micrometres.
- 15 micrometres
Explanation from PART66Online
Single-mode fibre uses a very narrow core, on the order of a few micrometres, so that only one light path propagates; among the options 5 micrometres is the single-mode figure. The larger 50 micrometre core is characteristic of multimode fibre, which carries many modes at once.
