BT's breakneck broadband test hits unimaginable speeds over plain ol' fiber
BT still has a long way to go until it connects all of Britain's homes to its fiber-optic network, but that hasn't stopped the company from exploring new ways to squeeze some extra speed out of it while it does. With a little help from friends at Alcatel-Lucent, BT boffins have created what they believe is the fastest-ever "real-world" internet connection, clocking speeds of 1.4 terabits per second using readily available hardware. If you're wondering how fast that is, the telecom giant says the network can transmit 44 uncompressed HD movies in a single second. While the project currently exists purely as a speed test, BT and Alcatel-Lucent are already talking up the possibilities of improving existing services like Infinity without having to dig up roads, potentially delivering broadband that can handle an influx of Ultra HD content on Netflix with less chance of suffering connection issues.
Panasonic teases 42.5mm f/1.2 and 150mm f/2.8 MFT lenses, slated for release by 2014
Panasonic further reinforced its commitment to the Micro Four Thirds form factor when it released the Lumix GH3 mirrorless camera today, but the company also announced the development of a pair of prime lenses, set to ship next year or in 2014. Details are spotty at this point (limited to what you see in that slide above, in fact), but you can expect a 42.5mm f/1.2 optic (85mm equivalent) and a 150mm f/2.8 lens, which offers a 35mm equivalent of 300mm. There wasn't even a hint of pricing, but we'd expect both of these offerings to be quite costly, though they'll likely be significantly less expensive than DSLR equivalents.
Panasonic launches 12-35mm Micro Four Thirds lens with constant f/2.8 aperture
As powerful as they've become, Mirrorless camera systems can't match the versatility of a full-size DSLR. One key component we haven't seen is a constant-aperture lens, offering a consistent large aperture size throughout the zoom range. That changed today. Panasonic's new Lumix G X Vario 12-35mm optic packs one incredible advantage over its compact competitors -- a constant f/2.8 aperture. Because of the Micro Four Thirds system's 2x multiplication factor, this 12-35mm lens covers the same zoom range of 24-70mm glass on a full-frame camera, in a significantly smaller package. The optic consists of 14 elements in nine groups, and includes UED and UHR lenses to increase image quality and minimize distortion, along with built-in image stabilization and Panasonic's Nano Surface Coating to reduce ghosting and lens flare. It's also splash- and dust-resistant, and features a metal mount on the rear. Panasonic has yet to release pricing in the US, but the European price tag has been estimated at €1,100 (about $1,400) -- by comparison, Canon's equivalent optic (from a specification perspective) will run you $1,600. For its part, the 12-35mm MFT lens is expected to hit stores in August. Full PR is just past the break.
Lensbaby Composer Pro gets Samsung, Sony, Micro Four Thirds mirrorless mounts
Lensbaby faithfuls awaiting a mirrorless-compatible Composer Pro lens need not hold out any longer. The company's high-end creative optic is now shipping for mirrorless mounts of the Samsung NX, Sony NEX and Micro Four Thirds variety -- including the Panasonic Lumix G and Olympus PEN. These latest additions join Canon, Nikon, Sony Alpha, Pentax K and Four Thirds versions, which are all available for 300 bucks at the source link below.
New undersea cables planned for arctic passageways, frozen gamers dream of lower pings
Hot on the heels of our own reporting of cables in the South Pacific (or the lack thereof), in flies a report that at least two new undersea cables are being planned for the arctic. According to New Scientist, a pair of lengthy fiber optic wires will be laid through the Northwest Passage above North America, connecting Japan to the United Kingdom. Moreover, a third cable is planned along the Russian coastline, with the longest of these links to purportedly become "the world's longest single stretch of optical fiber." A number of outfits are on the list to help out, and when complete, the latency between Tokyo and London should be reduced between 168ms and 230ms. The cost for such luxury? An estimated $600 million to $1.5 billion for each line. In other words, totally worth it.
Sony promises eight more NEX E-mount lenses by the end of 2013, doesn't elaborate
Have you been holding out on that NEX purchase because of the currently limited E-mount lens selection? Well, Sony's got some good news for you -- there will soon be eight additional lenses to choose from (for a total of 15), with all models making it into circulation by the end of 2013. That's still no match for the hundreds of optics available for Canon or Nikon DSLRs, but you'll at least be able to build a collection that covers (almost) all of your bases. Sony hasn't detailed any of these upcoming models, but the company's chart above lists a few categories, including a High Performance Standard Zoom in the pricey Zeiss category, along with High-magnification, Standard, Wide Angle and Mid-magnification Zooms. There will also be a trio of prime lenses, including a Large Aperture Standard lens, a Middle Telephoto and a "Snap" (pancake) optic. We're just as anxious as you to find out exactly what Sony has in mind for each of these categories, but you should at least take some comfort in knowing that the E-mount collection is far from complete.
Shaw plants 100Gbps fibers in Canada, watches them grow
Consumers can dream of 1Gbps, businesses might ask for 10Gbps, but here's the next step along that logarithmic curve: Shaw and Alcatel-Lucent just launched a new 100Gbps inter-city fiber optic network in Canada, following a successful trial between Calgary and Edmonton. The network can purportedly handle 133 million simultaneous voice calls, 440,000 HDTV channels, or transmit the equivalent of 44 Blu-ray discs in a single second. More redweed details in the PR after the break.
University of Twente's new lens reveals the sub-100nm level with visible light
Small is beautiful, but only when you can see it. Specifically, we're talking about nanostructures -- including cellular organelles and nanoelectronic circuits -- around the order of 100nm. The problem is with a microscope, visible light only takes us down to a resolution of 200nm at best, and it's not always ideal to use conventional methods to boost the resolution -- you'd either have to dope the subject with fluorescent dye or use highly delicate equipment. Thankfully, the University of Twente has come up with a new type of lens that would solve this problem: in a nutshell, a nanoparticle is placed on one side of the gallium phosphide lens, while the other side -- disorderedly etched with acid -- takes in a precisely modulated laser beam and scatters it into a focal point of your choice. Sure, this sounds bizarre and ironic, but apparently the modulation is controlled in such a way that the scattered beam focuses much tighter than an ordinary beam would using an ordinary lens. Have a look at the comparison shots of some gold nanoparticles after the break -- that's some sweet 97nm resolution right there for ya.
Lensbaby goes practical with aperture-adjustable Sweet 35 Optic
We love a Lensbaby lens as much as the next hipster, but if there's one thing the Optic Swap system isn't, it's fast. Switching out aperture plates is a royal pain, and for those looking to simply capture moments as they happen, it's a system that simply doesn't work. The company's apparently aiming to fix that with the introduction of its first 35mm optic with a 12-blade adjustable aperture. The Sweet 35 select focus optic requires but a twist to change the aperture, and in turn, the "sweet spot." 'Course, you'll still need to find yourself adequate light (or boost your ISO / slow your shutter) before stepping that aperture value up too high, but at least now it's easier than using a magnetic tool to fish one plate out and drop another in. The lens has a maximum aperture of f/2.5 and steps all the way down to f/22, and it'll focus down to 7.5 inches from the front of the lens. The downside is that this particular optic isn't compatible with current 37mm Lensbaby accessories, nor will it function with the Composer with Tilt Transformer for Micro Four Thirds and Sony NEX cameras. Still, for $180 it's easily the most practical thing the company has ever delivered, and we definitely hope this is just the beginning of a trend it intends to push.
Intel's 50Gbps Silicon Photonics Link shines a light on future computers (video)
Using copper cables to transfer data around a computer? Get your head out of the sand, Grandpa! Intel thinks that's on the outs and is touting its recent accomplishments with Silicon Photonics and integrated lasers, using light pulses to move data at 50Gbps (last time we heard Intel tout the tech was when it hit 40Gbps speeds in 2007). The emphasis is on low-cost, high-speed fiber optics, the removal of cable clutter, and with the speed boost, the ability to try new system designs by being able to space chips and components farther apart from one another without as much hit on speed -- all theoretical at this point, of course. Researchers hopes to hit terabit per second speeds further down the line. As for John Q. Consumer, enjoy the progress from afar but don't count on seeing this technology hit Newegg anytime soon. Video after the break.
Lensbaby Composer, Fisheye and Soft Focus review: creativity abounds
Lensbaby lenses have been out and about for a long while now, but we were just recently able to sit down with a few of the company's best and brightest in order to form our own opinions of the (admittedly overlooked) creative devices. For those unaware, Lensbaby makes a handful of lenses and optics that help users engage in selective focus photography, and frankly, create all sorts of wild images that would be otherwise difficult or impossible to create within Photoshop. There's no question that these are hobby lenses through and through -- you wouldn't want to hinge your business on these -- but are they worth the comparatively low asking prices? Read on to find out. %Gallery-88228%
Lumus-Optical unveils microdisplay-packin' designer glasses
While we admire the effort of those gaudy, unsightly microdisplay-equipped goggles to bring big screen theatrics to the front of your face, they aren't likely to win any style contests, nor help you garner any friendly attention. An Israeli company, dubbed Lumus-Optical, is looking to change all that by offering up a relatively normal looking set of spectacles with twin microdisplays and mini projectors. The firm's latest prototype boasts dual 640 x 480 resolution displays as well as a wee projector on the arm; the Lumus glasses can accept video inputs via an undisclosed connection, and projects an image akin to a "60-inch screen from 10 feet away." Its Light-guide Optical Element (LOE) technology allows the imagery to be reflected back on to the lenses so users can view them, all while being transparent enough to allow you to focus on the humans, trees, road block, or board room presentation ahead of you. Although it's easy to shrug gizmos like these off as gimmicky and unrealistic, we guess we'll have to see (ahem) for ourselves when these specs are demoed at CES.
Flat optic fibers = cheaper HDTV's?
That's what this Israeli firm says. They claim that they can create LED's for screens that are flexible, consume less power, and have better light dispersion. This way they could work their way into everything from your T-shirt to your HDTV.Of course this could be a ways off as LED's haven't replaced CCFL in LCD screens yet but an HDTV that you can wear? Sounds good to me.
