Optical transmission is becoming common technology for high-data transmission not only for telecom/datacom but for consumer electronics. There are a lot of types of optical transmission such as embedded optics (On Board Optics, CPO (Co-packaged Optics)), Pluggable optics and Active optical cables. Most of them are based on glass or silicon materials. On the other hand, Nitto have been developing new types of products for optical transmission, Plastic Optical Fiber and Optical waveguide with Flexible Printed Circuit (OFPC) based on polymer technology. In this presentation, I would like to introduce them and explain how our technologies will contribute to implementing optical communication in wider market.
Optical communication is widely applied and continues evolving. Embedded optics is focused on by a lot of companies for datacom application. Then some associations have started to discuss implementation of it as COBO (On-Board Optics), CPO (Co-packaged Optics) and NPO (near package Optics). Even in consumer application, Active Optical Cable (AOC) is gradually utilized for TVs and head mount devices. These trends require that the optical transmission products must have better performance and be more user friendly.
In this presentation, I would like to introduce a new plastic optical fiber (POF) and an optical waveguide with a flexible printed circuit (OFPC) both of which Nitto has been developing. They can contribute higher data rate including multi-level modulation, stronger against bending, downsizing modules and higher density optical packages.
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.
