I heard that Telecom has a broadband package called FTTR. What WiFi(FTTR?

All-optical WiFi(FTTR) is an indoor ultra-Gigabit network coverage scheme provided by China Telecom for domestic users, and it is a successful application of all-optical network technology. It can achieve effective signal coverage, so that every room can enjoy a stable and high-speed network experience. All-optical WiFi adopts "wavelength division multiplexing" technology, laying optical fiber in each room to replace the traditional network cable, thus breaking through the transmission bottleneck of the traditional network cable and achieving super gigabit transmission speed. At the same time, all-optical WiFi can also realize intelligent management and maintenance, and improve network reliability and security.
