G.fast standard ratified by ITU

The ITU announced December 5 that its members successfully met industry's "by the end of the year" expectations for ratifying the G.fast standard. The organization added that its ITU-T Study Group 15 is already hard at work on extensions.

Recommendation ITU-T G.9701, "Fast Access to Subscriber Terminals (FAST) - Physical layer specification," will offer carriers who aren't ready to invest in fiber to the home (FTTH) a way to provide broadband access services at data rates greater than VDSL2 with vectoring can provide. The goal of the standards makers and vendors who expect to offer the technology is 1 Gbps – although just how such services levels will work and when they might be available remain something of a mystery.
