KT Corporation Leverages Longtime Partner DZS to Make the Leap to Multi-Gigabit Speeds in Southern Korea

DALLAS, Jan. 31, 2023 (GLOBE NEWSWIRE) -- DZS (NASDAQ:DZSI), a global leader of access, optical and cloud-controlled software defined solutions, today announced that KT Corporation (formerly Korea Telecom), the Republic of Korea's largest wireline broadband service provider and a DZS customer since 2005, has chosen the DZS Velocity Access EDGE platform and advanced optical line terminal (OLT) technology as the foundation for its new 10 Gigabits per second (Gbps) Fiber-to-the-Premises (FTTP) Ethernet Passive Optical Networking (EPON) infrastructure across the country's southern half including the Daegu, Busan and Gwangju regions. The network upgrade will support world-class residential and business internet, voice and video services throughout the region.

"To prepare for new demands for bandwidth-intensive services that we know are coming, KT is upgrading our existing 1Gbps network infrastructure to 10Gbps with the DZS Velocity Access EDGE platform," said SangWook Kim, Director, Access Network Technology, KT. "The latest Velocity system not only provides us with the ability to deliver up to a ten-fold data rate improvement per port, but it also allows us to reach 50% more subscribers per platform despite being 40% smaller than the previous generation. The new platform's deployment flexibility, cost-effectiveness, due to its high density and ongoing energy and space savings, and proven reliability were key to our selection of DZS, as well as a long-term relationship where we have demonstrated superior service expertise and customer focus."

"The Republic of Korea has consistently been recognized as a broadband and 5G world leader, with some of the world's fastest mobile and broadband internet speeds and many of the most advanced applications, including large-scale AR/VR/XR and metaverse," said Daniel Won, Chief Customer Officer, Asia at DZS. "We are proud that we continue to earn the business of our long-time partner and global telecommunications leader, which is relying on DZS to create their next-generation EPON access network infrastructure for both residential and business customers. We are one of the leading network equipment developers and vendors in all of Korea and by deploying DZS Velocity platforms, KT will both significantly enhance their PON network and outpace their competition with world-class 10 gig services."

DZS offers among the industry's widest selection of Access EDGE, Subscriber EDGE, Optical EDGE and cloud-based network orchestration and experience management solutions to drive multi-gigabit network performance and a differentiated subscriber experience. By leveraging DZS platforms, "service providers" can rapidly transform into "experience providers" as they enhance their access and/or middle mile networks, better leverage and analyze the service performance and data available in the network and maximize their return on investment (ROI). DZS systems, platforms and technologies are standards-based, have proven interoperability with most vendors' equipment, and are designed to be managed and orchestrated alongside third-party solutions.
