Built for AI traffic between data centers

The new offering positions the 800Gbps dedicated line as a high-capacity link connecting data centers, where moving massive datasets between sites has become a bottleneck for AI development and operation. Dedicated lines provide customers with private, reserved network capacity rather than shared public internet paths, which KT is presenting as a key advantage for enterprises handling sensitive or bandwidth-intensive AI workloads.

KT's rollout comes as Korean carriers compete to supply the network infrastructure underpinning the domestic AI buildout, with data center interconnection a growing focus as clusters of AI servers are distributed across multiple sites.

Carrier competition in AI infrastructure

The launch adds to a series of AI-focused network initiatives by Korean telecommunications providers, as operators seek to move beyond connectivity services into roles supporting AI data centers directly. High-speed dedicated lines of this class are typically marketed to hyperscale operators, enterprises running large language models (LLM), and AI infrastructure providers that require guaranteed capacity between facilities.

The company did not announce pricing or named customers in connection with the launch, and details on rollout timelines for specific regions were not disclosed.

KT's AI dedicated line, with maximum speeds of 800Gbps, is now available, and the claim that the company launched the service to strengthen data center connectivity is true.
