World’s first implementation of a 4-core standard cladding diameter multi-core fiber transmission unit in a real system handling uncompressed 8K video
National Institute of Information and Communications Technology (NICT)The National Institute of Information and Communications Technology (NICT) the Advanced ICT Research Institute, ASTRODESIGN, Inc. , and Fujikura Ltd. have developed a multi-core fiber cable consisting of eight 4-core, standard cladding diameter multi-core fibers, and they have successfully implemented it for the first time as an ultrahigh-capacity data transmission unit in a real system handling uncompressed 8K video.
In an uncompressed 8K video system, approximately 70 Gbps of data must be transmitted per video stream, requiring one single-core single-mode fiber for each uncompressed 8K camera. The developed multi-core fiber cable contains a total of eight standard cladding diameter (125 μm) single-mode 4-core multi-core fibers of two different types within a 3 mm diameter cable, which is equivalent to the 32 single-core single-mode fibers that are conventionally used in uncompressed 8K video systems.
In this implementation, by introducing a transmission unit that utilizes the multi-core fiber cable, we successfully achieved stable system operation by transmitting high-volume video data from multiple 8K cameras installed in a cleanroom, through limited-capacity information conduits and building interior spaces, over 300 m to an 8K video composition device located in a separate building.
This achievement enables the deployment of systems requiring high-capacity data transmission, such as uncompressed 8K video systems, even in cases in which conventional installation was difficult owing to limited space in information conduits or wiring pathways within or between buildings.
