That's why I actually ask. E.g. "light travels approximately 1.5x slower through optical fiber than in a vacuum" https://www.commscope.com/globalassets/digizu

- bloggie 4y agoFun and somewhat related fact - this is one of the main advantages of hollow-core transmission fibers! As far as I know, currently only used to extend the range of HFT orgs...
- ccakes 4y agoTerrestrial radio links are similar in that they can be lower latency than fibre though spectrum concerns can come into play.
- brianwawok 4y agoRadio links can also often be straighter. Easier to go over someone’s house then ask permission to dig a trench.
- itishappy 4y agoHollow core fiber? Total internal reflection requires the core to be a higher index of refraction than the cladding, so I wonder how that works! Turns out, it functions differently. Instead of total internal refraction it has to rely on weird physics like photonic crystals. The pictures are absolutely wild. https://www.rp-photonics.com/hollow_core_fibers.html https://www.rp-photonics.com/hollow_core_fibers.html https://www.google.com/search?q=hollow+core+fiber&tbm=isch https://www.google.com/search?q=hollow+core+fiber&tbm=isch
- aaronax 4y agoFascinating; thanks for the links. I wonder how the splicing process works for that.
- Arnavion 4y ago("1.5x slower" == "its speed in optical fiber is 1/1.5 = 2/3 of the speed in vacuum")
- discordance 4y agoIt's all relative.
