Application of optical communication systems to satellite communications has started. On the other hand, radio frequency (RF) communication is used widely at present and stable service is offered. RF communication will coexist with optical communication in the future and hybrid systems will be enabled to exchange information widely and seamless networks will be built. Under this background, NEC has initiated a study of RF optical eXchange (RFOX) since January 2019, by using a ground evaluation model of RFOX (GRFOX). In this chapter, we will report on the study approach, schedule and progress to date.
