The retransmission device is installed in tunnel to redelivery AM/FM radio waves. FM radio uses LCX(*) for receiving antenna, but LCX has large transmission loss in the long-distance tunnel. To solve this problem when FM radio is used for long-distance tunnels, it uses optical relay. We provide high-frequency products that are RoF(*), Transmission/Reception amplifiers, etc. for optical relay.

(*) LCX ： Leaky CoaXial cable
(*) RoF ： Radio On Fiber
