Alcatel-Lucent 's ultra-broadband G.fast solution is now in trials with a dozen carriers around the world and is exptected to become available in the first quarter of 2015. Announced test sites include A1, a subsidiary of Telekom Austria, in which a regular subscriber was connected in order to independently test G.fast in the field. Other trials have included BT and Orange.
Alcatel-Lucent said its new 7368 ISAM single-port G.fast Optical Network Terminal (ONT) can deliver speeds of up to 1 Gbps over existing telephone lines. Alcatel-Lucent’s G.fast ONT can also be deployed in a multiple-dwelling unit, with one ONT serving each household. Customer trials use a multi-port G.fast solution using vectoring technology to eliminate the cross-talk interference that occurs when two or more copper lines are in close proximity, which adversely affects speeds. The multi-port G.fast solution will drive the evolution of Alcatel-Lucent’s VDSL2 micro-node portfolio.
The company also noted a recent Bell Labs demonstration of XG-FAST technology, which achieved symmetrical speeds of 1 Gbps over 70 meters of copper in the lab.
