A communications system is disclosed that includes at least one remote expansion unit (RXU) that is operatively coupled to at least one remote unit (RU). The at least one RU is configured to receive a first and a second downlink optical radio frequency (RF) communications signal. The at least one RU comprises at least one optical-to-electrical (O/E) converter configured to convert the first and second downlink optical RF communications signals to respective first and second downlink electrical RF communications signals. The at least one RXU is configured to receive the second downlink electrical RF communications signal from the at least one RU. The RU may comprise selection circuitry configured to identify which of the downlink electrical communications signals are sent to the RXU. The RXU may be configured to provide an uplink electrical RF communications signal received from a client device to the RU.
