minus-square@[email protected]linkfedilinkEnglish29•1 year 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-square@SquizzylinkEnglish3•1 year agoSo is hollow core fiber a vacuum or is it just hollow? I’ve never heard of that tech.
minus-square@[email protected]linkfedilinkEnglish7•1 year 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-square@SquizzylinkEnglish4•1 year agoI work with fibre and have never stopped to think if it is hollow or not. Thanks for this
minus-square@[email protected]linkfedilinkEnglish2•edit-21 year 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

minus-square@piecatlinkEnglish1•1 year agoThe properties of light in air is pretty similar to that of a vacuum. Air has a lot more empty space than a solid or liquid.

How do you weld that?
Absolutely no idea.
