caseys Posted May 26, 2011 Share Posted May 26, 2011 Makes dense wave division multiplexors seem quite redundant... I'd worry about the attenuation on that signal though and the need for repeaters over distance. We can get about 10x that bandwidth now via about 2000 fibres, which'd still be thinner than say a coke can. Also it's application really. If you're laying dark fibre lay multiple fibres. I doubt we're going to see any transceivers that can run that, heck 16gbps sfps are only just emerging. Still, nice to see people pushing those boundaries.

Wez Posted May 26, 2011 Author Share Posted May 26, 2011 The key here is single laser and fibre, they had 100tb already but required 370 lasers, this tech allows 26tb with a single laser and fibre Quote Link to comment Share on other sites More sharing options...
Scott Posted May 26, 2011 Share Posted May 26, 2011 WTF kind of memory array runs those sort of speeds? Does it live in a cryogenic swimming pool? I know nothing about the ins and outs of it all but I'd love to see it all working Quote Link to comment Share on other sites More sharing options...

WTF kind of memory array runs those sort of speeds? Does it live in a cryogenic swimming pool? I know nothing about the ins and outs of it all but I'd love to see it all working Well some ramsan/fusion IO and more exotic storage arrays can easily run in excess of 1,250,000 IOPS I've read which is 500gbps roughly on 256kb/iop. Otherwise I think this'd become a technology to help you span nodes in any HPC configuration - shunting data between memory/CPU rather than disk or slow flash/SSDs.

caseys Posted May 26, 2011 Share Posted May 26, 2011 You sure about that? http://www.speedtest.net/result/1313159161.png I just did this test on my BT Broadband. Good ADSL2? Or a bridged connection? http://www.theregister.co.uk/2011/05/25/bt_fttp_trial_rollout_delayed/ BT has been forced to delay the rollout of its fibre-to-the-premises (FTTP) technology, after roughly a quarter of its trials found engineers taking two days to blow cables into customers' homes. The telco's "superfast" broadband programme director Johnny McQuoid told The Register that some of the trials were taking twice as long as anticipated due to duct blockages that needed to be cleared. Some people who had dug up their gardens presented headaches for BT engineers, who have found the infrastructure troublesome. Shame really, woudl be good to get some competition with Virgin Quote Link to comment Share on other sites More sharing options...

Thing is though I am currently connected to the hub via cable as wireless speeds are rubbish. Could most likely be my laptop which either needs an new external wireless card or the drivers for the current wireless need updating (Lenovo T60). Though like you said BT have been having trouble and no competition to Virgin but I can't get virgin in my area Quote Link to comment Share on other sites More sharing options...

Though like you said BT have been having trouble and no competition to Virgin but I can't get virgin in my area It may be that the aerials in your wireless card just aren't up to the job. just because the card's 802.11n compliant, doesn't mean it'll reach the 802.11n ideal speeds Shame about that, though the new Virgin/Tivo box looks impressive. we had the whole 'fibrecity' thing going on (100Mb/s for £25/month) and then the firm seems to have gone bust, so lots of roads in bournemouth dug up, fibre laid about the place and then it's ground to a halt.
