Alcatel-Lucent, France, announced that its Bell Labs, a research and development arm in the United States, has achieved data transfer rates of 10 gigabits per second over traditional copper-core telephone lines. This technological breakthrough means copper broadband transmission speed comparable to optical fiber, is expected to solve the bottleneck faced by universal access to the home.
According to reports, researchers use a prototype called XG-FAST technology, which is an extension of the new broadband standard technology G.fast.
In the test, researchers achieved symmetrical broadband speeds of 1 gigabite per second over a single 70-meter long pair of copper cables, at the same time achieving up to 1 gigabyte per second for upload and download speeds, while at 30 meters Achieve 10 gigabits per second on dual pair copper wires.
Alcatel-Lucent said that the symmetric broadband speeds of 1 gigabits per second is a major breakthrough in copper broadband that allows operators to use copper to provide broadband access at rates equivalent to fiber-to-the-home, making it an important commercial value.
Subject to physical, economic and aesthetic factors, some places should not be laid directly to the new fiber. One way to solve this problem is to deploy optical fibers to the curb, wall or basement of a building, using the existing copper network for the last few meters of broadband access.
Analysts said that the last few meters of some broadband networks are still usually copper instead of optical fibers, which is the bottleneck restricting the FTTH. If the copper broadband transmission speed and fiber equivalent, this problem can be solved.
Alcatel-Lucent also said XG-FAST technology will enable operators to speed up their fiber-to-the-home initiative and promote their broadband access services using existing copper network infrastructure.
