Fiber optics harnesses the total internal reflection of light within thin glass or plastic strands to transmit data at staggering bandwidths across continental distances. From the critical angle that traps photons inside a core to the erbium-doped amplifiers that boost weakened signals without electrical conversion, every stage of optical communication rests on precise physics.
These simulations let you explore critical-angle acceptance cones, watch multimode pulses broaden as they travel, trace OTDR loss profiles, pack wavelength channels into dense WDM grids, and tune EDFA pump power for optimal gain — all with real-time interactive canvas visualizations.
