LG U+ Builds Backbone Network in South Korea

South Korea’s LG U+ will establish a ROADM backbone network to strengthen the competitiveness of its business and has selected Ciena’s WaveLogic 5 Extreme and WaveLogic Ai coherent optical solutions. LG U+’s newly constructed and dedicated nationwide ROADM backbone network will satisfy the needs of customers and preemptively respond to increased traffic following the introduction of the remote era.

Sung-Cheol Koo who’s in charge of LG U+’s wired business said, “Amid the expansion of cloud services such as telecommuting, video conferencing, and remote classes, we are building a new backbone network that can accommodate the needs of various corporate customers. With a flexible and stable transmission network, we expect that companies can provide a higher level of service.”

With rapidly increasing traffic, Ciena will enable LG U+ to transmit single-carrier 600G wavelengths over the new flexible grid backbone that has six times the network capacity compared to the existing network. The new backbone network will provide enhanced availability through low-latency, multiple route diversity, and direct connections between large cities without the need for regeneration.

LG U+ is in the process of implementing a major capacity upgrade, including multi-terabits of additional capacity, to accommodate large-capacity customers and enable stable traffic management. By applying OTDR (Optical Time Domain Reflectometer) technology to all sections of the backbone network, real-time and intuitive line condition monitoring is possible to shorten troubleshooting time and enable smooth network management and operations.

In addition, Ciena’s 6500 ROADM equipment can reliably configure DR (Disaster Recovery) line services to public government, financial institutions, and computing centers of large enterprises through third party interworking certification. LG U+ can also provide a dedicated line service with enhanced security through optical transport encryption.

LGU+ will be using Ciena’s Manage, Control, and Plan (MCP) SDN controller to be able to automate service delivery via next-generation OPEN APIs to improve customer experience and increase operational efficiencies.

LGU+ develops telecommunications services, high-speed internet, VoIP, and IPTV services as well as other data services. In fact, LGU+ is the first in the world to establish a nationwide LTE network with super high-speed services of the highest quality.
