Broadbandtrends recently released the results of its latest Global Service Provider Survey: 2018 G.fast Deployment Strategies & Vendor Leadership.
Broadbandtrends conducted a global service provider survey of broadband operators regarding their plans to deploy G.fast technology within their network. G.fast is a fiber‐to‐the‐distribution point (FTTdp) architecture offering up to 2Gbps aggregate speeds on copper infrastructure over very short loop lengths.
Key findings of the survey include the following:
The top objective for deployment of G.fast is to offer faster speeds (>250Mbps)
80 percent of survey participants plan to deploy G.fast by the end of 2018, with 27 percent currently in live deployments
Cost remains the greatest challenge facing operators planning to deploy G.fast technology
Fiber‐to‐the‐Building with the DPU in the Basement was cited as a top use case for 100 percent of survey participants
Average downstream speeds of 500‐1Gbps are expected with most G.fast service
9‐16 line DPUs remain the “sweet‐spot”
Support for 1Gbps aggregate speeds; extended bandwidth at 212MHz; and Dynamic Timeslot Assignment were consider the most important emerging/newly available G.fast capabilities
Continuing advances in broadband copper technologies, such as G.fast, are extending the life of the copper plant, offering faster speeds that will support the wide range of high-bandwidth applications on the horizon, while providing operators with a time to market alternative to FTTH – often at lower cost.
With aggregate speeds up to 2Gbps, G.fast is offering operators an opportunity to address both the competitive environment and time-to-market pressures, but it is the ability to offer these faster speeds, primarily to MDUs with copper infrastructure that is the key objective for operator interest in G.fast.
Cost remains a top concern for operators planning to deploy G.fast. Factors contributing to cost concerns include the need to deploy fiber further into the network, as G.fast requires significantly shorter loops than VDSL2 Vectoring; the potential need for external power depending on DPU location, as well as new CPE. In addition, since the distribution point will likely serve a smaller number of customers than ADSL or even VDSL2 Vectoring, the cost per subscriber is likely to be higher.
Operators continue to be tactical in their deployment over the next two years with virtually all of the focus on MDU deployment scenarios.
Operators are most excited about the ability to support 1Gbps aggregate (upstream + downstream) speeds – as the ability to offer faster speeds is the #1 objective for the deployment of G.fast. Additionally, interest in newly available features such as extended bandwidth at 212MHz as well as Dynamic Timeslot Assignment, also rated high in importance with operators.
Broadbandtrends’ Global Service Provider G.fast Deployment Strategies survey analyzes the results from interviews with 33 incumbent and competitive operators in all major regions, about their plans and deployment strategies for G.fast. The report provides a global overview of the results as well as commentary on any notable regional differences found in the results.
