A fiber fed repeater can be either channel selective or band selective. It receives the RF signals from the base
station via a HUB or an OptoBox which translates the RF signal to an optical signal and sends it to the
repeater via a fiber optic cable. The repeater unit can be installed up to 20 km away from the base station.
Inside the tunnel leaky feeders or antennas can be used for transmission to the mobile units.
