Through the use of G.fast and VDSL2 over short copper loops, it has become possible to provide broadband users with data rates approaching those of fiber access technologies. This capability allows service providers to provide ultra high-speed broadband service without the need to deploy fiber into the customer premises. Since the targeted copper loop lengths are typically less than 400 meters (250 meters with Reverse Power Feed), a node type that supports very deep deployment in the access network is required. This Working Text defines this node type by detailing its position(s) in the network and functional requirements. In addition, the functional requirements for reverse power feeding of this node type and its management architecture are specified. This Study Document will analyze the multiplicity of use case categories gathering inputs from service providers and network operators.Active FANCE Projects

This Internal Report is intended to provide a certification test plan for ITU‑T Recommendation G.9700 “Fast access to subscriber terminals (G.fast) – Power spectral density specification” and G.9701 “Fast access to subscriber terminals (G.fast) – Physical layer specification”. This IR-337 is specifically conceived for the basic interoperability objectives of the Broadband Forum G.fast Certification Program. Technical content in this test plan includes test setup information, equipment configuration requirements, test procedures, and pass/fail requirements for each test case. With short copper loops required by G.fast Distribution Point Units (DPUs) that push the deployment of the DPU/MDUs closer to the customer premise, local power and forward power may not be viable to cost or location. To power the DPU, power will come from the customer premises location over the copper pair; this is referred to as Reverse Power Feed (RPF). This document specifies tests for the RPF functions of a DPU and the customer premises’ Power Supply Equipment (PSE) either as a stand-alone device or as a function integrated in a G.fast Network Termination. Test cases are mainly specified with reference to ETSI TS 101 548 and BBF WT-301 requirements. Furthermore they are designed to ensure safe deployment of RPF equipment. This document applies only to the operational aspects of the certification program, such as: This document provides a performance test plan for ITU‑T Recommendation G.9701 “Fast access to subscriber terminals (G.fast) – Physical layer specification”. Since network architectures and deployment practices vary greatly among service providers, the network conditions (loop models, noise models, loop lengths, etc.) were selected to represent nominal conditions under which (interoperability) performance is tested. This test plan is focused on ensuring laboratory repeatability such that equipment from different vendors can be validated and compared.Active Gfast and RPF Projects
