Telephone Wire Could Be 3X Faster Than Consumer Fiber for High Speed Broadband
- rini17 5y agoOf course nowhere anything about distance. 30 meters?
- giuliomagnifico 5y agoThe research is here: https://www.cam.ac.uk/research/news/existing-infrastructure-will-be-unable-to-support-demand-for-high-speed-internet https://www.cam.ac.uk/research/news/existing-infrastructure-... I think the distance is calculated with attenuation because also a short cable can have lot of noise. But I think also the speed could be reached at longer distances than 30m, at least 200/300m
- boesboes 5y agoThe theoretical limit they discuss in the paper is 100gbps over 300m, 1tbps at 100m. So that seems a lot like a log function? Soo, 10gbps with 900m & 1gbps at 2700m. Theoretically atleast :)
- giuliomagnifico 5y agoUsually the degradation is not linear as you said. So about 1gbps at 2000m would be excellent compared to now that least we can have 2/300mbpbs at about 1/200m. Obviously there’re lots of variables on the copper, really a lot. Also every EU’s country has a different infrastructure.

- ksec 5y agoWe have Terabit DSL, G.Fast, XG.Fast DSL. I think post pendamic we can all agree on we need faster, more reliable internet connection to every home. And Fibre is the only way to go. Hopefully all the leaders around the world can understand that and spend some money making 1Gbps Internet connection much like the old phones line or water pipes. A requirement in home.
