LS Cable & System Advances Development of Multicore Optical Fiber for 5G and 6G

LS Cable & System has embarked on securing core technology for multi-core optical fibers used in 5G and 6G communications. Multi-core optical fibers are next-generation products that dramatically increase data transmission capacity compared to the current single-core optical fibers.

At the 'Next-Generation Optical Communication Technology Cooperation MOU' signing ceremony held on the 13th at LS Yongsan Tower, Lee In-ho, CTO of LS Cable & System (third from the left), Kim Du-geun, Deputy Director of the Korea Photonics Technology Institute, and other officials are posing for a commemorative photo.

On the 13th, LS Cable & System announced that it signed a 'Next-Generation Optical Communication Technology Cooperation MOU' with the Korea Photonics Technology Institute. The two parties plan to expand cooperation in optical communication technology and personnel exchange, starting with the development of multi-core optical fibers.

Optical fibers, as thin as a strand of hair, are used as the core of optical cables. Currently, single-core fibers are used, but the data transmission capacity increases proportionally with the number of cores, enabling a revolutionary increase in communication speed.

Lee In-ho, CTO of LS Cable & System's Technology Development Headquarters, said, "Multi-core optical fiber technology is highly challenging, with only a few companies in Europe and Japan having succeeded in its development," adding, "We will secure core technology and participate in technology standardization to take the lead in the next-generation communication cable market."

Meanwhile, LS Cable & System expects the demand for communication cables capable of large-capacity data transmission to surge as ultra-high-speed communication infrastructure expands worldwide. Accordingly, the company is expanding related businesses, including acquiring shares in KT Submarine, a specialized submarine optical cable construction company.
