Siemens Reaches 107 Gbps Data Transfer Record 161

Posted by samzenpus from the greased-lightning dept.
prostoalex writes "Reuters is reporting on Siemens engineers reaching 107 Gbps data transmission record over a fiberoptic cable, and expects the technology to be on the market within a few years: "The test, 2.5 times faster than a previous maximum transmission performance per channel, was done in cooperation with Germany's Micram Microelectronic, the Fraunhofer Institute for Telecommunications and Eindhoven Technical University of the Netherlands.""

        Yes it will actually, this is a bigger pipe, and since the internet is a series of pipes..

        But really, if an Aussie ISP (internode for instance) has just upgraded from 3Gb/s to around 6Gb/s, how much would it benefit them if they could just sell off most of the fibre they are using currently and just run one at 107Gb/s?

        As for 25MB/s, a newer HDD will easily reach around 40-50MB/s, added with the popularity of NAS and small raid systems most good PCs can suck almost 70MB/s (560Mb/s).

        Of course, with Australian broadband being lucky to get (until just recently) above 1.5Mb/s this is rather moot.

Also the distance doesn't really matter(remember, how do you think the contients are connected? single link fiber), because if it's a good cable the data should travel at the speed of light.
