Next-generation Optical Communication

For future high-density and high-capacity transmission, Optical Fiber we are developing Multi-Core Fiber (MCF), which has multiple cores in one fiber, for practical use. Fujikura is continuing research and development to propose MCF technology as a total solution customer including not only fibers but also peripheral technologies such as cables, connectors, and fusion splicing.
Fujikura has developed manufacturing technology to fabricate 600 km MCFs from a single base material with high precision dimensions ahead of its competitors, and is also working on development for even larger MCFs. MCF cables mounted with 288-fiber 4-core MCFs were laying into ducts, and 576 input/output devices were fusion-connected at both ends of the cable, and between buildings. The results of field verification were presented at an international conference, demonstrating the advanced nature of our research and development. We are also working on the development of technology to application MCF to 24-fiber MPO connectors that can connect 24 fibers at once. This technology makes it possible to accommodate 96 cores in a single connector at high density. Furthermore, MCF with Fujikura's SWR^Ⓡ / WTC ^Ⓡ technology enables greater transmission capacity and smaller cable diameters in high-density, small-diameter optical fiber cables. This technology is expected to be used in applications requiring high-density optical fiber transmission networks, such as data centers.
As the volume of information and communication traffic increases, so does the demand for electricity. This creates a global issue because of the resulting increase in energy consumption and its associated environmental impact. Reducing loss in optical fibers and minimizing connection losses can decrease power consumption.
Additionally, replacing metal transmission with optical transmission promises significant reductions in power consumption. We will continue to advance development in this field.
