Network traffic is growing by 30% to 50% every year due to the rapid spread of smartphones and the growth of data centers. To address this challenge, a great deal of research is taking place into how to boost network capacity. Space-division multiplexing (SDM) is attracting a lot of attention, which realizes multiple spatial channels within a single optical fiber. Among various types of optical fibers for SDM, multi-core optical fiber (MCF) is one of the most promising candidates for the next-generation transmission medium.

Sumitomo Electric has been at the forefront of MCF research since 2009. Recently, we collaborated with the University of L鈥橝quila to build the world鈥檚 first field-deployed MCF cable testbed in the city of L鈥橝quila, Italy. Various experiments using MCFs have been conducted in labs so far, but this testbed realize the experiments in an actual working environment, and will accelerate the practical realization of MCF communication systems.

The inauguration of the testbed was marked with a ceremony attended by local dignitaries, including the President of the Abruzzo region, the Mayor of L鈥橝quila, and the Rector of the University of L鈥橝quila. Mr. Toshiaki Kakii, Managing Executive Officer of Sumitomo Electric, said, 鈥淪umitomo Electric is much honored to take part in the world鈥檚 first field demonstration experiments of MCFs. We expect that the evaluation of the transmission performance of the MCFs in the actual usage environment will bring us many novel findings.鈥

The Ambassador of Japan to Italy, H.E. Mr. Keiichi Katakami, also attended the ceremony and delivered the message expressing his hope resting on the operation of the testbed. 鈥淚 am certain that the opportunity of the Italy鈥揓apan joint demonstration test of this leading-edge technology is crucially significant for promoting future technical and economic exchange between both countries.鈥

Sumitomo Electric will continue to contribute to infrastructure construction for building an advanced information and communications society, through research and development of next-generation optical fiber cables.
