IBM researchers will showcase a prototype optical transceiver chipset that they claim allows people to download movies, etc, 8 times faster than current technologies.
At the 2007 Optical Fiber Conference, IBM researchers will showcase a prototype optical transceiver chipset that they claim allows people to download movies or share online data eight times faster than what current technologies allow.
The researchers say that the technology will transform the way data is accessed, shared, and used across the Web for corporate and consumer networks. The transceiver is fast enough to reduce the download time for a typical high definition feature-length film from what usually takes 30 minutes or more, to just about a single second.
IBM researchers believe that the ability to move information at speeds of 160 Gigabits or 160 billion bits of information, in a single second, provides a glimpse into a new era of high-speed connectivity that will transform communications, computing, and entertainment.
In a statement, T C Chen, Vice President of Science and Technology, IBM Research, said, "The explosion in the amount of data being transferred, when downloading movies, TV shows, music, or photos, is creating demand for greater bandwidth and higher speeds in connectivity. Greater use of optical communications is needed to address this issue. We believe our optical transceiver technology may provide the answer."
To achieve this new level of integration in the chipset, IBM researchers built an optical transceiver with standard Complementary Metal Oxide Semiconductor (CMOS) technology, and then combined this with other necessary optical components crafted from exotic materials such as Indium Phosphide and Gallium Arsenide. The resulting package is just 3.25mm by 5.25mm in size, small enough to be integrated onto a printed circuit board.
Meanwhile, IBM is claiming its technology could pave the way for devices that almost instantly transmit a digital X-ray to a doctor's hand-held screen, a seismic analysis to an oil engineer's workstation, or movies around home networks.
why should we download a entire movie in 1 s since we can not watch it in 1 s ...? streaming through networks (xDSL, 3G+, ...) should be sufficient for most of the cases!
This is a problem comm cos have been trying to solve since the invention of fiber-optic cable. Optical transmission is very fast, but has to be converted to electronic at every routing juncture. If routing can occur without the time lost going from optical to electronic and back to optical, then they will have removed the "brakes" on the internet. Modern telephone switches already far exceed the data rate of the PCI bus in a PC, let alone the hard-drive. Somebody needs to get that halographic cube storage ready...
by the way, electrical signal propagation isnt generally any "slower" than light propagation, it is just that the higher frequency light wave can be modulated at a higher rate, thus will carry more information...bandwidth being the cosequence of modulation it also reflects the rate of modulation or information content in simple terms...Fourier comes to mind...I think u may need to first get a theoretical grasp of what is involved in old fashioned rf communication, modern methods are not any different as far as their structure...
Doesn't the speed of a DSL connection limit the download speed more so than the 'speed' of the computer? Not sure, but I am getting same d/l speeds off a 5 year old piece of crap dell and a 2 year old p4 :S
This is surely all technically possible, but I doubt telcos will allow end users to have a 160Gbit/s download stream in the next 10 years. It will be still download limits, speed limits, only for some few to have an overpriced premium service of let's say 1 Gbits/s. Ironically, cities in developing countries (China / India) will have the best download and upload speeds - they do today already.
I can easily see this being dumped into say a very large Flash cache. From there it could dump to your HD. The speed is still an issue but as we are seeing ram tranfer rates rising as well we may se this becoime a viable technology in the near future. HD's as we knwo them are not goign to survive much longer. Specially with the coming of holographic storage. Holographic stroage is capable of 20 MB/s. And this technology is still in it's infancy. Don't look at a future tech and assume we will be interfacing it with current tech.
well that's very nice, but my hard drive isn't going to be able to write 4.5gb of data (the size of one dvd - i.e., the high definition movie) in one second. still, they have handed the baton over to the hard drive/solid state drive manufacturers if the storage transfer speeds are now the limiting factor as it seems.
