Evolving technology for more speed, capacity, and efficiency
AT&T Labs began evaluating next-gen 25GS-PON technology in our production network in June 2022. This expands our broadband network’s capacity by almost 2.5x compared to XGS-PON while requiring minimal infrastructure upgrades in our central offices and customer locations. And it runs over the same fiber optic cables we’ve spent the last decade-plus installing nationwide. In our trial, we were able to take advantage of wavelength coexistence with our FiberWise™ technology – combining 25GS-PON with XGS-PON and other point-to-point services over the same fiber to offer an efficient evolutionary path. This technology is what enabled us to reach 10 Gigs earlier this year and 20 Gigs today in our Broadband Lab in Austin, TX.
Symmetrical 20 gig capability gives developers and engineers a huge runway to the future. As concurrent and mass use of AR/VR, the metaverse, autonomous cars, telemedicine, robotic manufacturing, real-time video sharing and editing, and gaming continue to grow, our 20 Gbps service will provide plenty of bandwidth – that includes helping make possible connected apps and services that haven’t even been imagined yet.
Future of ultra-fast broadband
The 25GSPON MSA group – consisting of more than 50 global operators and suppliers, including AT&T – is the industry group driving the standards and specifications of this new tech. We expect the group to bring 25GS-PON to maturity in the next 6 to 12 months. Looking beyond the 25GS technology, we are also actively engaged and driving 50 Gbps and 100 Gbps symmetrical access technologies with global standards bodies. As we invest and build towards our goal of becoming America’s best broadband provider, we’ll keep working on what comes next while helping drive the broadband evolution even further into the future.
