8.45 Gfast Certification, Testing, and Standardization - Lincoln Lavoie Sen.Eng. for broadband Technologies / UNH-IOL
In the past 12 months (since the BBWF 2016), Gfast has moved out of the labs, and into the field. This evolution has been made possible through the success of the Broadband Forum Gfast Certification Program, launched in June 2017, in combination with supporting plugfest activities. Looking at what has been achieved, it's critical that service providers utilize the certification program, setting clear expectations for CPE and DPU performance and stability. Here, we'll provide a detailed look into the certification program, as well as the coming enhancements to the Gfast Technologies from the ITU-T.
9.05 GFast is ready for the Gigabit era - Rami Verbin CTO / Sckipio
To be successful a G.fast product has to combine good performance (coverage) with the right level of CAPEX and OPEX. This presentation deals with innovative technologies used to meet this target, making G.fast ready for the Gigabit era.
9.25 Dynamic Timing Assignment in GFast - Werner Heinrich Director Portfolio Management / Adtran
Dynamic Time Assignment (DTA) takes advantage of variation in subscriber traffic to optimize the capacity offered over G.fast at any given moment. In doing so, the technology can radically improve subscriber Quality of Experience, as well as expand the set of services offered by providers. In this presentation, we show how DTA works in two variations – independent and coordinated – and present expected performance improvements enabled by the technology. We also show how it can enable symmetric service offerings that significantly exceed those available using static TDD techniques.
9.45 The evolution of power requirements in converged access networks - Rudy Musschebroeck Director, Business development / Commscope
As bandwidth demand continues to increase, fiber optics are making a steady progression deeper into converging access networks. To avoid the high cost associated to a full fiber to the home deployment, many operators turn to technologies such as DSL, G.Fast, FiberDeep, remote phy or even 5G fixed wireless radios, using existing coax or copper infrastructure or even wireless links. At the same time, densification of the wireless networks is paving the road to 5G. All these architectures require an increasing amount of active electronic devices at the edge of the network, each serving an ever-smaller number of subscribers. This evolution leads to an increased requirement for power in the edge of the network, introducing new challenges for deployment and operations. The dielectric nature of fiber optics makes connections to the utility grid the default practice today. This session will explore the associated challenges and alternative solutions to provide power to the edge of the network.
10.05 Standardization of xDSL and MGfast in ITU-T - Hiroshi OTA Study Group Advisor, ITU/TSB
This presentation gives an overview of standardization activities of xDSL and MGfast in ITU-T SG15, in particular, Question 4/15 (Q4/15). While the latest VDSL2 reaches 400 Mbit/s, there is still a technology gap between FTTH. G.fast and MGfast fill this access technology gap. After a brief introduction of Q4/15, an overview of access network solutions over metallic conductors are shown. Then, key aspects and important features of G.fast and VDSL2 are described. Collaboration with the Broadband Forum is also touched as an important element of standardization. Finally, future work of G.fast and the outline of the emerging G.mgfast are presented.
10.25 The DSL roadmap from G.fast to Terabit-fast - John M. Cioffi CEO ASSIA
Use of higher-order waveguide modes are explored for increasing the speeds of twisted-pair data rates to levels as high as 1 Terabit/s over 100m. A path to significantly improve DSL speed/range is reviewed in terms of significantly advance beyond the lengths for G.fast and G.mgfast through these modes use. 1 Gbps symmetric speeds at the low end at ranges of 600-700 meters and 10 Gbps at 500 meters are reviewed as intermediate steps to the eventual Terabit DSL. The steps and complexities of advancing to these capabilities are suggested and reviewed.
