In January, AT&T launched impressive speeds up to 5 Gbps with its fiber Internet service in more than 70 American cities. Today, AT&T Fiber announces that it has successfully achieved ultra-fast symmetric speeds of 20 Gbps with its production network.

AT&T says it’s “laser-focused” on being the “best broadband provider in America.” In a update On its progress for faster speeds, improved capacity and lower latency, the company shared that it has achieved massive download and upload speeds of 20Gbps with its production network after hitting 10Gbps earlier This year.

How AT&T fiber reached 20 Gbps

AT&T touts being the first carrier in the world to achieve speeds of 20 Gbps in testing, and June’s achievement was made possible by “coexistence of wavelengths.”

“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 on the same fiber to deliver a scalable path efficient. This technology allowed us to reach 10 GB earlier this year and 20 GB today in our Broadband Lab in Austin, TX.

While there is no timeline for the launch of symmetric 10-20 Gbps speeds for commercial customers, AT&T believes the 25GS-PON technology supporting these advancements could be ready as soon as the next 6-12 month”.
