DSL (Digital subscriber line), one of the initial technologies that heralded the era of high-speed Internet, is set to leap into the future, with Broadcom announcing a new technology that will allow speeds of 1 gigabit per second through DSL.
That increase is about 1,000 times the data-transfer speed the technology offered when it debuted in the late 1990s.
The announcement was made at the Broadband World Forum 2014 in Amsterdam on October 21, 2014. The technology is known as G.fast, a standard from the International Telecommunication Union, in which fiber optic cables carry data close to residences, from where copper cables carry the data into homes. The advantage of this technology over pure fiber optic networks is that a lot of the copper has already been laid, providing major savings in time and investment.
However high-speed DSL networks may still have downsides. Gigabit speeds can only be practical over short distances between broadband providers’ fiber node and the customer. Longer distances lead to degradation in signal quality. BT, the British multinational telecommunications company, has stated that it tested speeds of 786 Mbps over 19 meters of copper and 696 Mbps over 66 meters.
