Group 1 Blog: http://rfogrupo1.blogspot.com European FTTH. In an interesting article in Fibre Systems Europe, HartwigTauber, president of the FTTHCouncil Europe, discusses how some Asian and American public policies have supported fiber deployment and acted to remove ambiguity and uncertainty from the regulatory process. According to Mr. Tauber, this seems to be the main reason for which Europe lags behind the From February to June, Group no. 1 shall maintain a weblog giving more details about the European fibre access and related news. The work developed here will be used for your assessment as well as the wiki page you will create reporting on the subject, that should give an overall picture on fibre access networks in The dominant broadband access technologies today are DSL and cable. DSL leads, with global subscribers exceeding 100 million, while cable-modem subscribers worldwide totaled 55 million at the end of 2005. DSL and cable will probably remain as the dominant broadband access technologies through to 2009. However, emerging broadband technologies such as fibre access gain in importance, growing at 17% a year between 2004 and 2009. Fibre access comprises different technologies including PON technologies (read this article.). The other important piece will be Ethernet point-to-point. |

Group2 (NO SE HIZO ESTE TRABAJO DURANTE ESTE CURSO) Bit-rate of 40Gpbs is no longer taboo and we've been hearing about it again since 2005. However, there are several reasons not to assume that faster is necessarily always better. Read this article and learn about how vendors keep and eye on traffic growth and where in the network 40Gbit/s can make an impact. There is and there has been an intense research work on 40Gbit/s components and demonstrators that you should track in this blog from February to June. All this will be used for your assessment as well as the wiki page you'll maintain on 40Gbps optical networks reporting on the main conclusions. You may want to check recent advances in 40Gbit/s technology in this article on 2005 Research and Development (R&D) highlights. You may also need to study the offer of the leading companies in optical networking solutions and see the bit-rates they provide. Keep also an eye on their news and plans for future speed upgrades, if any. Include Mintera in your search. Finally, it might be interesting to check recent scientific papers on 40 Gbit/s technology. Go to the UPNA's library main-page, click on the "Portal de Revistas" link and look for papers in the IEEE Photonics Technology Letters and IEEE Journal of LightwaveTechnology, for instance. |

Group 3 Blog: http://rfogrupo3.blogspot.com Wikipage: http://www.seedwiki.com/wiki/rfo_grupo_3/rfo_grupo_3.cfm The Optical Internet. The optical internet is an optical network with all-optical routing of IP packets. The goal is to route the IP packets without the bottleneck of having to convert all the optical information to electrical packets in the routers. Several alternatives allow for this to be achieved. With all-optical label swapping, for instante, SCM is used to distinguish between labels, which provide the routing information, and the payload. Only the optical labels are converted to the electrical domain and the payload remains all-optical from the source node to destination. Several other techniques have been proposed in the recent literature. Look for them and describe them to your colleagues. Use your blog to discuss the issue and provide up-to-date information. Summarise your main conclusions in your wiki page. |
