LG U+ first to deploy 600G backbone network in Korea with Ciena’s ROADM equipment
South Korea network operator LG U+ today announced it is the first carrier in South Korea to deploy 600Gb/sec on a single wavelength for long haul, using Ciena’s WaveLogic 5 technology. LG U+ made this upgrade to support remote experiences.
The company will establish a ROADM (Re-configurable Optical Add-Drop Multiplexer) backbone network to strengthen the competitiveness of business. 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. For this network transformation, LG U+ has selected Ciena’s WaveLogic 5 Extreme and WaveLogic Ai coherent optical solutions.
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.”
LG U+ also applied the Optical Time Domain Reflectometer (OTDR) technology, which measures the loss of optical lines, disconnection points, and distances across the entire section of the new backbone network. By intuitively monitoring the condition of the line in real time, it is possible to shorten the response time in case of a failure.
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 compute 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.
