Abstract
An optic Distributed Antenna System includes a Head End (HE) configured to adjust a first signal for a first carrier at a first band to a first level, to adjust a second signal having at least a carrier different from the first carrier or a band different from the first band to a second level, to combine the first and second signals, to perform Electronic/Optic conversion on the combined signal, and to optic-distribute and send the combined optic signal, and a plurality of Remote Units (RUs) each connected to the HE over a corresponding single optic line, wherein each of the RUs is configured to perform Optic/Electronic conversion on the combined optic signal, to adjust the converted signal for each signal band, to perform high-power amplification on the adjusted signals, to multiplex the amplified signals, and to transmit the multiplexed signal to a Mobile station via at least one antenna.
