South Korean telecom operator KT has introduced a dedicated AI line service offering bandwidth of up to 800 Gbps, expanding capacity by a factor of eight compared with its existing dedicated line offerings, according to reporting carried by Korean news outlets including Yonhap News, ET News and ZDNet Korea on October 14, 2026.
The new "AI dedicated line" is aimed at enterprises and institutions that need to move large volumes of data for AI training and inference, such as transfers between data centers or links to cloud GPU clusters. Conventional dedicated lines that companies use for general business traffic fall short of the throughput demands of modern AI workloads, which involve massive datasets and frequent large-scale transfers between computing sites.
The headline specification is a maximum bandwidth of 800 Gbps. That represents an eightfold increase over the bandwidth ceiling of KT's existing comparable dedicated line service, according to the figures cited in the coverage and KT's published materials on the launch.
The announcement comes amid intensifying investment in AI infrastructure across Korea, where telecom operators have been positioning their fiber networks as a backbone for data center interconnection and AI computing deployments. KT has been among the carriers promoting AI as a core growth area alongside its traditional connectivity business.
The coverage, published on October 14, 2026, was accompanied by images of the service announcement distributed by Yonhap, ET News and ZDNet Korea. Details on pricing, availability timelines and specific customer segments for the new service were not fully laid out in the material reviewed; readers should treat commercial terms as unconfirmed until KT publishes its formal tariff details.
A dedicated line of this bandwidth class is typically marketed at large enterprises, AI startups operating their own GPU infrastructure, and public institutions building AI systems. By raising the bandwidth ceiling eightfold, KT is seeking to differentiate its enterprise connectivity business as demand for high-capacity, low-latency links between AI computing sites accelerates in Korea.
No competing service specifications or other carriers' responses were included in the reviewed reporting.
The claim that KT has launched an AI dedicated line with bandwidth of up to 800 Gbps, an eightfold increase over its existing offering, is supported by the reported figures and the company's announcement materials, so the claim is True.
