Abstract: Provided is a repeater-type radio relay system that can prevent loop interference of radio waves with the same frequency and does not require a frequency for relaying. The radio relay system is provided with one or more optical fibers for relaying an optical communication between a relay-source radio relay apparatus and a relay-destination radio relay apparatus. The relay-source radio relay apparatus has a network-side communication section for communicating with a mobile-communication network side, and an electro-optical signal conversion section of relay source for converting between an electrical signal in the mobile-communication network side received from the network-side communication section and an optical signal propagating through the optical fiber. The relay-destination radio relay apparatus has a terminal-side communication section for wirelessly communicating with the terminal apparatus side, and an electro-optical signal conversion section of relay destination for converting between an electric signal in the terminal apparatus side received from the terminal-side communication section and an optical signal propagating through the optical fiber.
