Alcatel-Lucent Shows Eco-Sustainable Broadband Access Gear

Alcatel-Lucent highlighted its role in bringing to the market technologies that will help reduce green house gas emissions.

Two existing technologies - Alcatel-Lucent's distributed digital subscriber line access multiplexer (DSLAM) concept, as well as a series of passively cooled fiber-to-the-building (FTTB) DSLAMs - are now complemented by a whole new range of eco-sustainable indoor optical network terminals (ONTs), which are located at the customer's premise and convert optical signals back into electrical voice, video or data.

Alcatel-Lucent said its new compact indoor ONTs consume up to 30 percent less power than earlier designs. Its distributed DSLAM concept - supported by the Intelligent Services Access Manager (ISAM) family of products - enables service providers to manage up to 24 times fewer nodes in FTTB or fiber-to-the-node architectures, resulting in more cost-effective operations. Additionally, through the use of simplified backplanes, power consumption is reduced by up to 20%.

At home, a number of important savings can be made as well. By introducing FTTB DSLAMs with a so-called "passive cooling" mechanism, up to a 10 percent power savings can be realized compared to traditional FTTB DSLAMs that are actively cooled. An additional benefit lies in the elimination of all noise that traditionally accompanies an active cooling system.
