To support growing demand for high-bandwidth end-user services and applications, SK Telecom is cost-effectively increasing long haul DWDM capacity to Ulleungdo Island using 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.
"Uncompromising quality is critical in today’s transport networks as they scale to support ever-increasing amounts of customer traffic," said Petri Markkanen, General Manager and Vice President of Sales, Asia Pacific, Coriant. "Following rigorous testing for this submarine application, SK Telecom selected the Coriant hiT 7300 submarine solution for its superior 100G reach and performance, as well as proven features including flexible configuration, advanced optical link control, and integrated RAMAN amplification."
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.
