Abstract:
Embodiments relate to providing simultaneous digital and analog services in optical fiber-based distributed radio frequency (RF) antenna systems (DASs), and related components and methods. A multiplex switch unit associated with a head-end unit of a DAS can be configured to receive a plurality of analog and digital downlink signals from one or more sources, such as a service matrix unit, and to assign each downlink signal to be transmitted to one or more remote units of the DAS. In one example, when two or more downlink signals are assigned to be transmitted to the same remote unit, a wave division multiplexer/demultiplexer associated with the multiplex switch unit can be configured to wave division multiplex the component downlink signals into a combined downlink signal for remote side transmission and to demultiplex received combined uplink signals into their component uplink signals for head-end side transmission.

Claim (Index 8):
A method of operating a multiplex switch unit for a wireless communication system comprising a plurality of remote units having at least one antenna assembly and being optically coupled to the multiplex switch unit, comprising:\n receiving, at a plurality of head-end side inputs of the multiplex switch unit, a plurality of component downlink signals comprising at least one downlink radio frequency (RF) communication signal and at least one downlink digital data (DD) signal; assigning each component downlink signal received at the plurality of head-end side inputs to at least one of a plurality of remote side optical outputs of the multiplex switch unit, including assigning at least one downlink RF communication signal and at least one downlink DD signal to a common remote side optical output; for each remote side optical output:\n multiplexing the respective assigned component downlink signals into a combined downlink optical signal; and \n transmitting the respective combined downlink optical signal to the assigned at least one of a plurality of remote side optical outputs; \n receiving, at a plurality of remote side optical inputs, a plurality of optical uplink signals, each optical uplink signal comprising at least one component optical uplink signal, wherein:\n at least one optical uplink signal is a combined optical uplink signal comprising a plurality of component optical uplink signals; and \n at least one combined optical uplink signal comprises at least one uplink RF communication signal and at least one uplink DD signal; \n for each remote side optical input, receiving a combined optical uplink signal, separating each combined optical uplink signal into each of the respective component optical uplink signals; and transmitting each component optical uplink signal toward a respective at least one head-end side output.
