Deutsche Telekom, Nokia achieve 10G speeds over copper in XG-Fast lab trial

Deutsche Telekom and Nokia's (NYSE:NOK) subsidiary Alcatel-Lucent claimed they delivered 10 Gbps over existing copper wiring during a lab trial using XG-Fast technology at the end of 2015. 

Conducted at Deutsche Telekom's cable laboratory in Darmstadt, Germany, XG-Fast is the next stage of technology innovation in the copper plant.

During the trial, Deutsche Telekom demonstrated an aggregated bandwidth exceeding 11 Gbps on two bonded pairs of Category 6 copper cable over 50 meters. Previous tests using standard drop cable illustrated the feasibility of XG-Fast for what's become known as fiber-to-the-front-door applications, achieving aggregate rates exceeding 8 Gbps over 50 meters. All of the trials were performed using prototype equipment from Bell Labs in controlled lab conditions.

XG-Fast can also theoretically deliver 1 Gbps symmetrical services at distances of 70 meters, enabling operators to deliver fiber-like speeds inside buildings using existing telephone lines, eliminating the need to install new Cat-5 or fiber cabling. This allows for faster installation times and less hassle for the end-user in that technicians don't have to drill holes to run cable to connect to a home router or modem. 

XG-Fast fits in well with Deutsche Telekom's current network configuration, which consists of a mix of VDSL2 and vectoring as well as FTTH, allowing it to offer speeds of up to 100 Mbps.

Similar to other Tier 1 telcos, Deutsche Telekom is looking to new technologies like XG-Fast to broaden its higher speed broadband footprint to address areas where it can't immediately make a business case for FTTH. It could use this technology to fulfill the commitment to meeting Germany's national broadband targets.

DT is just one of many service providers looking at XG-Fast technology.

Fellow European telco BT (NYSE: BT) completed a demonstration of G.fast technology during which the service provider was able to deliver more than 5 Gbps over its existing copper pairs in October 2015. At the time of that demonstration, BT said it delivered aggregate speeds of 5.6 Gbps over 35 meters of copper cable.
