Welsh University crams more data down fibre optic networks
Hundred times faster broadband and 75% cheaper sounds enticing but some careful reading reveals that the existing infrastructure mentioned in the articles is referring to fibre-optic networks. Fibre-optic cable is at the core of broadband since it links the telephone exchanges and cable cabinets to places where the data we all download or upload is stored, but this research does nothing to improve that final few hundred feet or kilometres of metallic cable that both cable broadband and ADSL/ADSL2+ based services use.
A 1Gbps connection would download a 4GB film in around 32 seconds, so one can estimate that they are talking of speeds around the 10Gbps mark. The main thing we suspect this research is doing is reducing the cost of the hardware that would need to sit on either end of the fibre optic cable. The big costs of physically getting a fibre optic cable into the homes around the UK are still to see either someone willing to fund it with a view to a long term (30 year) benefit or a technology change that makes it considerably cheaper to install.
