AT&T is out of the starter blocks for 400G with an optical connection carrying live traffic between Dallas and Atlanta. AT&T said the 400-gigabit optical connection was the first of its kind in the industry, as most vendors are targeting next year for the release of their 400G networking gear. Having a 400G connection allows AT&T to have a fat pipe to serve up new 5G and broadband services for its consumer and business customers.
With a plan in place to have 5G available nationwide the first half of next year, AT&T plans to start deploying 400G across its network in 2020.
