minus-squareKazumara@feddit.delinkfedilinkEnglisharrow-up23·11 months agoThe financial types are generally more interested in hollow core fiber, to get their latencies even further down for high frequency trading. Because light travels at almost c in hollow core but only at 2/3 c in fiber core.
minus-squareSquizzy@lemmy.worldlinkfedilinkEnglisharrow-up3·11 months agoSo is hollow core fiber a vacuum or is it just hollow? I’ve never heard of that tech.
minus-squareGarytheSnail@programming.devlinkfedilinkEnglisharrow-up7·11 months agoThink glass pipe versus glass cylinder or rod. Though, I don’t think the hollow core is fully empty, it has some structure to it. Here is an example Source: https://www.rp-photonics.com/hollow_core_fibers.html

minus-squareGarytheSnail@programming.devlinkfedilinkEnglisharrow-up1·11 months agoAbsolutely no idea.
minus-squareKazumara@feddit.delinkfedilinkEnglisharrow-up2·edit-211 months agoI think that both hollow core fibers filled with air and others with just vacuum exist, but it’s a bit far from my operational reality, so I’m not that sure. I just read in industry news that euNetworks has deployed 45 km of Lumenisity hollowcore fiber and that Microsoft bought Lumensity

How do you weld that?
Absolutely no idea.
