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-squareSquizzy@lemmy.worldlinkfedilinkEnglisharrow-up4·11 months agoI work with fibre and have never stopped to think if it is hollow or not. Thanks for this
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.
