Thanks to advances to VDSL using techniques such as vectoring, copper wire continues to be a viable and cost-effective alternative to fiber and cable for expanding the reach of broadband networks, according to Niek Jan van Damme, a member of the Deutsche Telekom board. While copper may not be able to achieve the same capacity as fiber, van Damme says the 100 Mbps download speeds of vectored VDSL are more than enough to satisfy the needs of 90% of broadband users and can be deployed without the expense of laying new fiber.
