Pundits stared into their crystal balls and declared 2018 the year of Gfast, and they were right.
Within the first few months of this year, service providers passed about 3 million premises with Gfast networks, and approximately 29,000 households subscribe to these services, according to research released today from Point Topic. Most of these subscribers reside in Southeast Asia, the analyst firm said.
To date, 33 telcos and ISPs currently or plan to deploy this technology soon, Point Topic found. Of these, 14 are trialing Gfast and already have conducted lab tests, with some completing field trials. Another 13 now are rolling out Gfast within their internal networks and plan to launch commercially within the next 12 to 24 months. And the remaining six global providers already offer Gfast services to customers, with download speeds ranging from 300Mbp/s to 500Mbp/s, Point Topic determined.
"Now that the early implementations and some significant testing and pilot schemes are winding up we'll start to see real acceleration in network footprints and adoption," said Jolanta Stanke, research director at Point Topic, in a statement.
Mapping Worldwide Gfast Deployments in 2018

Examples of deployments include:
BT: Has committed to serving 10 million premises by 2020; covers 93,000 currently via fiber-to-the-cabinet (FTTC) and Gfast, for speeds of up to 330Mbp/s.
Swisscom: Deployed fiber-to-the-street (FTTS) Gfast to 70,000 premises, providing speeds up to 500Mbp/s.
Oi: Brazilian provider targets parts of Rio de Janeiro with Gfast and, when it debuted the service in 2016, planned to work with Alcatel-Lucent on to eventually extend speeds beyond 1Gbp/s into XGfast services of up to 10Gbp/s. But in December 2017 after months of financial turmoil, the operator filed for bankruptcy, no doubt impacting its Gfast plans among other things.
CenturyLink: Launched a pilot in 800 apartments in Wisconsin, and post-acquisition of Level 3 is reviewing future plans for Gfast and other access technology deployments.
Chunghwa Telecom: With 25,000 subscribers on Gfast, Point Topic names the Taiwanese provider the largest user of this technology.
AT&T: The service provider recently debuted Gfast services to Boston multi-dwelling units (MDUs) and plans to use Gfast to deploy broadband services to 22 metro areas outside its footprint (See AT&T Uses Gfast to Dish Out Broadband to Boston.)
nbn: Australia's government-run provider is slated to initially cover 700,000 premises with Gfast, it has said.
Combined, this adds up to between 6 million and 7 million premises that will be covered by Gfast by year's end, predicted Point Topic. If BT adheres to its plans, the total number could reach 10 million, the research firm said.
Where Gfast Fits
Fiber is time-consuming and expensive to deploy, especially to MDUs where apartment and condo residents may not own their units and building owners plus dwellers' associations ink deals with operators for discounted rates that cover all residences. With Gfast, providers bring fiber to the basement, cabinet or street, and then use units' existing copper or coax to cost-effectively and rapidly deliver high-speed broadband to each apartment.
In some cases, operators view Gfast as the first step to fiber: With fiber already in the basement, once an owner wants to deploy fiber to each unit a service provider can construct fiber-based infrastructure from this early investment, having earned revenue from the copper-based, Gfast-powered broadband during the intervening years. In other cases, providers simply see Gfast as a technology that continues to evolve, delivering faster and faster synchronous speeds that empower MDU residents to quickly upload, download, use telehealth, Internet of Things, smart home solutions and anything else they want.
In fact, providers such as Telekom Austria, BT, Swisscom and nbn are trialing next-generation Gfast, which promises speeds of up to 11Gbp/s.
Through a partnership with Additiv, the service provider delivers an OTT-like cloud-based offering that allows financial institutions to gain digital transformation without ripping and replacing mainframe legacy systems.
County Broadband, 10-year-old former WISP that focused on fixed wireless, now concentrates solely on gigabit fiber, courtesy of a £46 million infusion from Aviva Investors – and the financial firm's desire to find a long-term investment vehicle to fund clients' pensions.
On July 12, the FCC said it will discuss one-touch make-ready at its August general meeting. That same day, Clearfield announced general availability of a common fiber distribution panel designed for use in every fiber deployment.
We will explore several fiber network environments, common vulnerabilities, and the business impact of failures. Fiber networks are typically a combination of owned and leased fiber. Learn how to reduce MTTR by up to 60% when an event occurs and how to detect degradation before it generates a service impact. Fiber monitoring of leased fiber helps ensure that the responsible party is dispatched for repair and SLAs can be managed. We will discuss both in service and out of service monitoring. Learn about the opportunities to improve business results in the following environments:
Hyperscale datacenters- the business need for near 100% uptime
5G small cell combined with leased fiber - ensuring the SLA for leased fiber
Long haul and Metro dark and lit fiber monitoring - reducing MTTR and preventing damage
FTTX construction and service activation in the access or MSO network - accelerating time to revenue
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
