A team of researchers at Keio University (President: Kohei Itoh) has successfully developed a multi-core graded-index plastic optical fiber (GI-POF) capable of ultra-high-speed data transmissions at up to 106. Multi-core optical fiber, with its ability to transmit multiple signals simultaneously, has emerged as a promising solution to meet this demand. Additionally, due to its characteristics such as multi-channel transmission, high integration, spatial flexibility, and versatility, multi-core optical. The purpose of the present invention is to provide a multicore plastic optical fiber, an optical communication cable, and an optical communication system using them that are capable of using multiple cores for communication, excellent in fiber handleability, low in transmission loss, and wide in. WO2025204844 - MULTI-CORE PLASTIC OPTICAL FIBER, OPTICAL COMMUNICATION CABLE, AND OPTICAL COMMUNICATION SYSTEM The purpose of the present invention is to provide a multicore plastic optical fiber, an optical communication cable, and an optical communication system using them that are capable of. The optical fibers that underpin current communications are single-mode optical fibers (SMFs), which have only one core (the path through which light travels). The transmission capacity limit of SMFs is reportedly 100 Tbit/s. Meanwhile, communication volume is expected to continue to increase, and. 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. This technology will enable high-density, low-latency, and high-capacity.
