ITU Bumps G.fast to 2Gbps, Adds Support for Coax

The ITU-T Study Group 15 has doubled the G.fast standard to support top down link speeds of 2 Gbps.

The first ITU standard harnesses up to 106MHZ of spectrum frequency to deliver top speeds of 1Gbps on copper lines of less than 50 meters. The updated standard will allow 212MHz to be used.  The amendment also enables G.fast to be used over coaxial copper cables.

The amendment also specifies a mechanism for dynamic time assessment, functionality that enables upstream or downstream transmission to exploit G.fast’s full aggregate net data rate. This functionality will improve users’ broadband experience by increasing upload or download speeds in line with the demands of the applications in use.

In addition, the new ITU-T G.7701 “Common Control Aspects” describes commonalities in SDN and ASON network management-control, covering common SDN and ASON control approaches as they relate to transport resources and their representation, control components, control communications, and naming and addressing.
