LS Cable & System is making moves secure source technologies for multicore optical fibers used in 5G and 6G communication. 

LS Cable & System announced on the 13th that it had entered into an MOU with the Korea Photonics Technology Institute (KOPTI) for cooperation on  next-generation optical communication technology. 

Starting with the multicore optical fiber development, LS Cable & System and KOPTI plan to expand optical communication technology and personnel exchanges. Multicore optical fibers are next-generation products capable of groundbreaking increases in data transmission volume compared to existing single-core optical fibers. 

Optical fibers with the thickness of a human hair are used as the core wires for optical cables. Currently, single-core fibers are used. Using multicore fibers can achieve revolutionary increases in communication speed as data transmission capacity expands in proportion to the number of cores. 

“The development of multicore optical fibers involves a high level of technical difficulty that only a few companies in Europe and Japan have succeeded in overcoming,” said LS Cable & System Head of Technology Development Division and CTO In-ho Lee. “We will dominate the next-generation communication cable market by securing source technologies and participating in technology standardization.” 

LS Cable & System forecasts that the demand for communication cables capable of large-scale data transmission will increase rapidly as the establishment of high-speed communication infrastructure expands across the globe. Accordingly, the company is expanding its related business, such as by acquiring the shares of KT Submarine, an underwater optical cable installation specialist.
