ABSTRACT:
A base station in a cellular communications system is connected to a plurality of remote cellular sites by a communications link having a base terminal coupled to a remote terminal by two optical fibers. The base terminal receives RF downlink channels from the base station and optically transmits the RF channels as a non-overlapping composite signal to the remote terminal on a first fiber. The RF downlink channels are individually recovered at the remote terminal and distributed to disignated cell sites. The remote terminal also functions to receive RF uplink channels from the cell sites and optically transmit the RF channels as a non-overlapping composite signal to the base terminal on a second fiber. The RF uplink channels are indivicually recovered at the base terminal and forwarded to the base station.
