Fortunately, today most of the world’s broadband subscribers already connect to the Internet through copper lines that were originally deployed for traditional telephone services.

And because of exploding Internet access Telcos have been interested in finding ways to get more bandwidth out of their copper networks. It is an interest that has largely been fuelled by intensified competition from the cable operators and the resulting need for Telcos to start delivering the combination of video, data, and voice services: The Triple Play.

VDSL2 provides up to 100Mbps down/upstream in bandwidth. However, the maximum loop length of such high bandwidth is only about 150m to 500m depending on quality of the copper lines. It is a significant issue to broaden VDSL coverage and roll-out other bandwidth-driven applications.

Actual, an attractive Triple Play service package requires about 50Mbps per household – simultaneously enabling 1 or 2 high-definition television (HDTV) channels, high-speed Internet access, and Voice-over-IP telephony. Main drivers for additional increase of bandwidth will be: the delivery of multiple HDTV, Smart-TV and 3D-TV channels, symmetric HD video conference applications and the increasing popularity of video sharing and social media networks.
