    Sure, researchers have been showing off terabit data speeds in fiber optics for years, but they've seldom been practical. That exotic technology may work over long distances, but it can quickly fall apart when you throw typical network loads in the mix. However, it's about to become much more practical. Nokia Bell Labs, Deutsche Telekom and the Technical University of Munich have shown off 1Tbps data speeds in a field trial that involved "real conditions," with varying channel conditions and traffic levels.

    Looking for wicked fast internet? You may want to move to Denmark: researchers in DTU Photonics' High-Speed Optical Communications Group (HSOC) have set a new world record for single-transmitter data transfer. Using a new kind of optical fiber, the team was able to achieve transfer speeds of 43 terabits per second. Not familiar with bit-based statistics? Try this: that's more than five 1TB HDDs worth of data moved in less than one second. So, fast. The record was set using only a single laser transmitter, but faster speeds can (and have) been obtained using setups with hundreds of lasers.

  • Huawei tests 2Tbps data transmission over Vodafone's German network, calls it a 'first'

    As terabit speeds go, Huawei's latest fiber feat falls on the lower end of recent industry achievements. At 2Tbps, the Chinese company's field test -- one it's hailing as a "world's first" -- comes nowhere close to the 100Tbps-plus experiments conducted by the likes of NEC and NICT. But top speed isn't entirely the point here; real-world performance is. By leveraging existing fiber infrastructure owned by Vodafone across portions of lower Germany, Huawei was able to successfully demonstrate two record-breaking, 200G transmissions: one spanning 1,500km and the other 3,325km over an "ultra-long-haul solution." To give you a bit of perspective on just what sort of data haul theoretical networks of this kind can achieve, Huawei claims this ultra-fast connection is "equivalent to downloading 40 HD videos in one second." Impressive, indeed. But don't go ditching that TWC wideband or FiOS contract just yet. While it's nice to know this tech exists, practical deployment is still a ways off. Until then, gigabit's the buzz word.

  • IEEE pushes for Ethernet standard between 400Gbps and 1Tbps, hopes to head off big data crunch

    Ethernet might seem passé to those of us toting Ultrabooks, but it's important enough to provoke a crisis for internet providers and many of those who depend on high-speed computing networks for a living: based on the rises of streaming video and social networking, the IEEE is worried that many of those large-scale networks will need 10Tbps of total bandwidth just to avoid a logjam in 2020. To that end, the standards body has formed a Higher-Speed Ethernet Consensus group that's mulling a new, breakneck-speed format reaching either 400Gbps or 1Tbps, depending on whose approach you'd favor. Fight the urge to pick the 1Tbps option on instinct, however. Both options would depend on bonding multiple connections together, and the faster of the two formats could lead to some expensive and very ungainly cables if it's not handled well. A meeting is scheduled for late September in Geneva to at least begin hashing out the details. Although we won't be wiring our homes with terabit Ethernet anytime soon, the standard should come quickly enough that the Googles and Netflixes of the world can satisfy our data addictions for a good while longer.

  • ZTE blasts past the speed barrier with field test of 1.7Tbps data transmission

    That bank-breaking 150/35Mbps FiOS connection you're so proud to call your own? Yeah, it looks like dial-up next to the searing terabit speeds recently achieved by ZTE's optical network. The Chinese telco, mostly known stateside for its mobile handsets, has successfully completed an experiment designed to highlight the possibility of migrating "from a 100G transmission system to a 200G system." In layman's terms, that's a data punch of 200Gbps-plus sent over eight channels, which in this case, totals about 1.7Tbps. Impressed? You should be, but don't cast your home connection the side-eye just yet. Like Deutsche Telekom's comparatively lesser feat, you'll likely amass a few wrinkles and lbs before this tech becomes consumer-ready. Check out the official PR after the break.

  • Researchers create two 100 terabit per second optical connections, dare us to torrent something

    Even a woman with a 40 Gbps internet connection might feel a twinge of jealousy at this news -- Japan has successfully tested two separate 100 terabit per second data links that use a single optical fiber to carry their loads. New Scientist reports that NEC scholars stuffed the light from 370 lasers into 165 kilometers of fiber to achieve a speed of 101.7 Tbps, while NICT researchers set a new record of 109 Tbps using a special fiber with seven cores to manage the trick. We imagine that Alcatel-Lucent and NTT aren't sitting still. Not that we really care who has the fastest fiber... just so long as one end leads to our house.

  • '3D Towers' double disk storage capacity, don't require glasses

    Here's some exciting news for all you data storage enthusiasts and academics out there: researchers in France have found a way to double the storage capacity of magnetic disk drives by constructing "3D towers" of information. The team from SPINTEC created these pillars out of bit-patterned media -- separated magnetic nanodots, each of which carries one bit of data. By layering the dots in specific formations, the team created a "multilevel magnetic recording device" with an areal density of two bits per dot -- twice what it started with. According to researcher Jerome Moritz, these findings could provide IT companies with a new way to circumvent physical limitations to their data storage capacities, allowing them to build up and over the vaunted one Tbit per square inch barrier. The team's full findings were recently published in the American Institute of Physics' Journal of Applied Physics.

  • Alcatel-Lucent blows past data transmission record: 25.6Tbps

    Data transmission records were just made to be shattered, as we've seen the benchmark go from 2.56- to 14- and now to 25.6-terabits per second within a year (and five days, but who's counting?). The momentary record holder this time around is Alcatel-Lucent, which "successfully transmitted a world record 25.6Tbps of optical data over a single fiber strand' using 160 WDM channels. In case you were wondering, that's enough speed to send about 600 DVDs worth of information to your buddy in one single second, after which you'd likely destroy any and all functionality his / her computer previously had before the bombardment. Now, what's it cost to run one or two of these pipes to Sealand?

  • Fujitsu achieves another storage milestone using patterned media technology

    Although it seemed that Seagate was comfortably at the forefront of magnetic recording developments, Fujitsu is hoping that its latest "breakthrough" will add a little friction to the areal density competition. Using patterned media technology, the firm "was able to achieve a one-dimensional array nanohole pattern with an unprecedented 25 nanometer pitch," which essentially means that recording one-terabit per square inch onto HDDs of the future is now realizable. Additionally, the company also revealed a new development "involving perpendicular magnetic recording (PMR) read / write operation on random patterned media," which utilizes the soft underlayer (SUL) as the PMR media. As expected, the presenters weren't as forthcoming about when we'd actually see these achievements make a difference in our laptops, servers, and other HDD-equipped devices, but the sooner the better, okay Fujitsu?

  • NEC, Samsung stacking flash in hopes of a one-terabit chip

    It's a common adage that over time, consumer electronics get faster, cheaper, smaller (size) and bigger (capacity). In continuing with this tradition, NEC, Samsung and others are poised to introduce the next generation of flash memory by placing eight memory chips (each only 50 micrometers thick) and one controller chip in a vertical stack, with "3D connections" between all of 'em -- creating a tiny-sized but powerful piece of storage. Samsung says that this could lead to a one-terabit flash chip within the coming years, but don't count on fitting an entire season of "Lost" on your cellphone just yet -- company scientists say that these new chips are "in their early stages" and can only hold 32 bits for the time being.
