CuPON: the Copper alternative to PON 100 Gb/s DSL networks [Accepted from Open Call]

This article investigates the ultimate bandwidth limits of a copper DSL binder of 200 telephone line connections, finding the ultimate available shared data bandwidth to be 100 Gb/s. A new "Copper-PON" or, more compactly CuPON¹ multidropping DSL architecture enables DSL bandwidth sharing and increases data rates through exploitation of all modes of crosstalk, particularly with the use of vectored² dynamic spectrum management. The inevitable emerging conclusion raises an intriguing question about the broadband access evolution of telecommunications networks: Why deploy currently available or contemplated passive fiber systems when the existing last kilometer of copper can provide broadband gigabits per second to everyone?
