Alcatel/Lucent nearly double optical transmission speed to 25.6Tbit/s

Alcatel/Lucent says they've crushed the previous data transmission record of 14 Terabits per second. "Combined research teams from the United States and France successfully transmitted a world record 25.6 Terabits per second (Tb/s) of optical data over a single fiber strand, using 160 Wavelength-Division Multiplexed (WDM) channels." For those of you who need the long-tired DVD equivalent -- that's enough bandwidth to transmit more than 600 DVDs per second. Back in 2002, the record was 2.56Tbps Currently OC192 is the standard for ISPs with 10Gbit/s (not including multiplexing). OC768 (40Gbit/s) is currently in limited deployment The above metioned artice is OC-3072 (160Gbit/s) with 160 multiplexed optical wavelengths Official press release

Virgin Media Q406 results and 20Mbps launch date
Posted by joe (6 Comments)	Thu Mar 1st '07 08:05:27 PM
The main broadband figures indicate there were 78,100 net additions of broadband customers in the quarter. Virgin.net referred to in the report as the 'Off-net' business added 18,000 customers bringing its total to 260,800 connected via ADSL services. The most interesting facts for those that don't hold any Virgin Media shares is the news on new products is that the 20 Mbps cable broadband service is due to launch in June 2007 and a residential trial of a 50 Mbps service is on the way. For areas where Virgin Media does not have its own cable network, they are in the process of securing an agreement with a wholesale local loop unbundling provider, with the aim of launching a quad-play product (broadband, TV, landline and mobile) without massive capital investment. This year should also see the launch of a Digital Terrestrial TV set top box, which in 2008 will make use of an IPTV service that will include paid for broadcast channels and Video on Demand (VoD) for people outside cable areas and on unbundled exchanges. At the press launch of Virgin Media the planned 97% coverage for quad-play was a key point, but it seems unlikely that we will ever see a LLU provider unbundling that many exchanges, especially by November 2007 as was hinted at the launch. We believe that in 2007 for those not on the existing cable networks the TV component of any quad-play package will initially revolve around the Freeview set-top box service, with a limited number of people getting the IPTV component in 2007. This is likely to expand more in 2008. Most LLU providers are aiming for a 70% coverage figure during 2007 so other options such as Datastream may be used to provide quad-play on the smaller exchanges where unbundling does not make financial sense. It should also be noted that with the new wholesale broadband products as part of the BT 21st Century Network (21CN), IPTV may become more economic across the BT IP network using the various options that Wholesale Broadband Connect (wBBC) provides.

Quantim computer will appear.... around lunchtime next week?
Posted by play_boy_2000 (15 Comments)	Sat Feb 10th '07 04:14:46 AM
A COMMERCIAL outfit claims that it is ready to release what it is calling the first quantum computer. D-Wave of British Columbia has promised to demonstrate a quantum computer next week that can carry out 64,000 calculations at the same time in parallel "universes". The computer can massively speed up searches and optimisation calculations. If it has managed to do it, the computer could make current security systems obsolete as a quantum computer can crack any current cryptography scheme by providing an unlimited amount of simultaneous processing resources. The machine D-Wave wants to flog has only 16 qubits, but systems with hundreds of qubits would be able to process more inputs than there are atoms in the universe. Boffins wonder if the outfit has really got a Quantum computer to sell as they were not really expecting to see one for another 20 years. Still you get temporal distortions when you mess around with parallel universes, and the machine has probably invented itself in the future and sent itself back through time.

Mooninites Invade Boston
Posted by donkey (3 Comments)	Fri Feb 2nd '07 02:35:34 AM
Police in the US city of Boston are investigating a major American media corporation for causing a security alert that closed bridges and roads. Turner Broadcasting System placed electronic devices with blinking lights around the city as part of a campaign to market a late-night TV cartoon. Police were called out to investigate the suspicious-looking devices, which disrupted road and rail traffic. Police destroyed the first package they found to see if it contained explosives. Two men who placed the objects have been charged, state officials said.

On-demand BBC TV Edges Closer
Posted by donkey (1 Comment)	Thu Feb 1st '07 01:39:12 AM
The BBC wants to let viewers catch-up with television programmes via the net but the plans are proving controversial. To watch programmes on their PCs, viewers will have to download a piece of software known as the iPlayer. Both the service and the iPlayer tool will be available once the BBC Trust - an independent body that replaced the Board of Governors at the beginning of this year - has published its final approval for the scheme in May. The BBC Trust's initial approval comes with some interesting restrictions on the service as initially envisaged by the BBC. As well as limiting the time that people can store programmes on their computers to 30 days, rather than the proposed 13 weeks, it has not approved the bookmark feature which would allow users to highlight a programme they wanted to watch ahead of transmission. The Trust also recommends that the BBC adopts a more platform-agnostic approach to the digital rights management framework which protects the programmes offered for download.
