SK Telecom, Korea’s largest telecommunications company, has selected a Coriant submarine solution to extend 100G connectivity to Ulleungdo Island, which lies off the east coast of Korea.
The solution based on Coriant hiT 7300 Multi-Haul Transport Platform and Coriant Transport Network Management System (TNMS), will enable SK Telecom to enhance delivery of mobile broadband services on Ulleungdo Island, said Coriant.
To support growing demand for high-bandwidth end-user services and applications, SK Telecom is increasing long haul DWDM capacity to the island using the Coriant technology deployed in its nationwide terrestrial DCM-free 100G network. The Coriant unrepeatered submarine network solution will support resilient, low latency 100G coherent optical transmission over a distance of more than 250 kilometers.
According to Coriant, the hiT 7300 supports the secure and reliable transmission of 100G+ per channel, achieving a total system capacity of up to 9.6 Tbps per fiber pair via 96 x 100G channels.
According to Coriant, as SK Telecom extends its network and 100G service reach to Ulleungdo Island, Coriant TNMS will enable operations staff to seamlessly manage high-quality services across terrestrial and subsea network segments, while accelerating time-to-revenue with end-to-end point-and-click provisioning and full service visibility and control.
TNMS supports automation capabilities designed to minimize OpEx and perform routine network tasks including inventory management, network element configuration backup, and software upgrades, added the company.
