The 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.

So is hollow core fiber a vacuum or is it just hollow? I’ve never heard of that tech.

Think 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

I work with fibre and have never stopped to think if it is hollow or not. Thanks for this

How do you weld that?
GarytheSnail@programming.dev 11 months ago
Absolutely no idea.

I think that both fibers with air and those with 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
