Recently, Higher-resolution videos such as 4k8K are required in any fields and 5th generation of cellular networks, called 5G, is about to be installed. These trends need high-speed communication inside devices as well as intra devices. Most of all electrical companies is developing new gaming system of AR/VR or the other new products based on these technologies for consumer electronics. To meet the market demands, optical transmission using Optical Fiber has been developed and applied for connecting between devices, especially, Active Optical Cable (AOC) is focused on for the consumer electronics, which people can use easily such as a conventional copper cable. Then, Polymer optical waveguide is believed as the one of solutions to transmit optical signals inside devices. We have been developing Plastic Optical Fiber (POF) and Optical Flexible Printed Circuit (OFPC) from design of materials. Our new POF combines flexibility and high heat resistance. On the other hand, OFPC, which is combination of polymer waveguide and conventional FPC, can make the plug size of AOC smaller due to its unique coupling structure. Both of their characteristics can contribute to safety and usability of AOC. In this report, we describe the overview of our materials of POF and waveguide and their properties, then we introduce OPFC based on polymer optical waveguide.
