minus-squareKazumara@feddit.delinkfedilinkEnglisharrow-up28·1 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-squareKazumara@feddit.delinkfedilinkEnglisharrow-up2·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
