Bell Labs test shows faster speeds on shorter copper

Next generation cable technology – DOCSIS 3.1 – can support symmetrical 10 Gbps speeds over hybrid fiber coax plant, according to a press release from Bell Labs, now known as Nokia Bell Labs. Nokia completed its purchase of Alcatel Lucent earlier this year and Bell Labs was part of the bargain.

Bell Labs is pitching its XG-Cable technology for integration into CableLabs’ DOCSIS 3.1 standard, which is undergoing field trials in a few U.S. markets.… More

Forget gigabits, Bell Labs says petabits are coming

What’s a petabit for, if not more grumpy cats?

The theoretical fiber speed limit continues to increase. Bell Labs says it’s successfully tested technology that has the potential for moving data through an optical fiber at the speed of 1 petabit per second. A petabit is 1,000 terabits, which in turn is 1,000 gigabits. Currently, the top speed for optical fiber is in the 10 terabit to 20 terabit range, according to Bell Labs. The technique involves multiplexing six separate transmissions on a single fiber

Using the MIMO-SDM technique, Bell Labs aims to overcome the non-linear Shannon limit of currently deployed optical fiber.


Bell Labs goes looking for lost mojo

First we’ll invent Unix, then we’ll figure out what to do with it.

When Silicon Valley was just pear orchards and a junior university, and a google was an obscure bit of math trivia, the wellspring of geek creativity was a continent away. Bell Labs sprawled across several campuses in northern New Jersey, filled with scientists and engineers who were paid to come up with interesting ideas and novel technology. Not necessarily marketable products, although it was correctly assumed that profits would follow somehow.… More

Bell Labs bridges a gigabit over a copper gap

The case for copper. Source: Alcatel-Lucent.

AT&T and Verizon should think twice about running away from older copper networks. Bell Labs has prototype technology that can already move half a gigabit through legacy wiring. Testing by parent company Alcatel-Lucent and Telekom Austria succeeded in pushing more half a gigabit over multiple legacy copper POTS pairs, using elements of the emerging standard and mixing in advanced vectoring technology – dubbed Vectoring 2.0 – developed by Bell Labs.… More
