Introduction of Next-Generation Optical Transmission Equipment by US Siena
Untact Era... Traffic Response
Providing Stable Dedicated Network to Corporate Customers
[Asia Economy Reporter Minyoung Cha] LG Uplus announced on the 24th that it has completed the construction of a new nationwide backbone network dedicated to enterprises, applying the latest optical transmission technology, and has begun full-scale service.
The new backbone network construction aims to proactively respond to the rapidly increasing traffic in the non-face-to-face era and to provide a stable dedicated enterprise network for various business environments of corporate customers.
They introduced the next-generation optical transmission equipment ROADM (Re-configurable Optical Add-Drop Multiplexer) from Ciena, a global leader in the optical transmission field based in the United States. In particular, the network was built in a mesh topology directly connecting major metropolitan areas and 28 key cities nationwide, reducing latency and diversifying routes to enhance data transmission stability.
The newly introduced ROADM technology not only allows remote flexible reconfiguration of optical signals but also applies a variable wavelength method for the first time in Korea to respond to traffic. It can provide network capacity capable of transmitting up to 600G, which is more than six times the existing network capacity during traffic surges.
Additionally, direct interconnection with cloud data centers operated by enterprises makes network expansion configuration easy, enabling stable and high-quality traffic management for public institutions, large corporations, financial companies, and global enterprises.
LG Uplus also applied OTDR (Optical Time Domain Reflectometer) technology throughout the entire new backbone network section to measure optical line loss, break points, and distance. This allows intuitive real-time monitoring of line status, shortening response time in case of faults.
Through Ciena’s ROADM technology, which has obtained the most global SAN (Storage Area Network) interconnection certifications, disaster recovery line services can be configured more stably, enabling rapid response to failures or disasters.
Goo Seongcheol, Head of LG Uplus Wired Business, said, “With the expansion of cloud services such as remote work, video conferencing, and remote classes, we have completed the construction of a new backbone network that can accommodate the diverse needs of corporate customers. We expect to provide more advanced services to enterprises by offering a flexible and stable transmission network.”
