Broadcom today unveiled DSL chips that use the new G.fast standard to deliver up to 1Gbps broadband over copper phone lines. That doesn’t mean everyone who has DSL will suddenly get a huge speed upgrade. G.fast, a standard from the International Telecommunication Union , is intended for fiber-and-copper networks in which fiber delivers data close to homes and copper takes it the rest of the way. These networks are cheaper to build than fiber-to-the-home because they reuse existing copper, but thus far they haven’t been able to match the gigabit speeds of fiber-only service. Alcatel-Lucent’s Bell Labs and the British telecom company BT are both testing G.fast, with the latter using Huawei technology . Broadcom is now joining the party with technology it plans to sell to Internet service providers, who would then roll it out to their customers. The chips will power both the back-end technology needed to deliver high speeds as well as home gateway systems for Internet users. Read 7 remaining paragraphs | Comments
