The recent news of AT&T launching 400G network connectivity and Windstream successfully completing 400G trials has caught the attention of industry experts and potential buyers.

The 400G connection is a major upgrade to its existing network and is currently available on the long-haul network between Dallas and Atlanta. This move beyond a proof-of-concept sets a new standard for high-speed internet connectivity and has the potential to revolutionize how we access data. The success of Windstream LR optics, which can support 10 km coverage, further increases the flexibility of the interconnection between client routers and transmission systems.

While news of these advancements may seem technical, they have important implications for business users who depend on high-speed Internet connections to operate effectively. But who are the potential buyers of these 400G services?

It is clear that 100G services are mainly used as high-bandwidth wholesale services for operators and cloud providers. They are also used in high-end retail applications in enterprise verticals such as finance.  Potential buyers of 400G as a carrier service are likely to be businesses requiring extremely fast data transfer speeds, such as those in the financial and healthcare industries, which rely on a constant, uninterrupted flow of data to operate.

As the optical core network continues to expand to multi-megabit, the demand for 400G services will increase, and the ecosystem and cost per bit will become the controlling factors that need to be overcome. However, with the likes of AT&T and Windstream leading the way, the future looks bright for those looking to operate at the highest levels of network speed and efficiency.
