The Fiber Optics Museum
From glass threads to undersea cables — how light carries the internet. Watch total internal reflection in action, explore 30 artifacts, and calculate bandwidth.
TIR Simulator
When light hits a core-cladding interface at greater than the critical angle θc = arcsin(n₂/n₁), it's reflected with essentially zero loss. That's the trick — a strand of glass becomes a lossless light pipe, and a continent becomes a single hop.
The Collection
30 artifacts spanning 180 years of fiber optic innovation — from light fountains to submarine cables. Click any card to copy its description.

From Light Fountain to TAT-14
Key milestones from 1841 (Colladon's water-jet light fountain) to the 2020s (subsea cables crossing every ocean basin).
Hands-on Instruments
Calculate critical angles for common fiber materials, compute fiber-optic bandwidth with DWDM stacking, and browse the world's intercontinental cables sorted by year or capacity.
95% of intercontinental data travels through submarine fiber cables.
