Power management for remote antenna units in distributed antenna systems
摘要
說明書
To provide digital data services in the optical fiber-based distributed antenna system 120 in this embodiment, a digital data services controller (also referred to as “DDS controller”) 124 in the form of a media converter in this example is provided. The DDS controller 124 can include only a media converter for provision media conversion functionality or can include additional functionality to facilitate digital data services. The DDS controller 124 is configured to provide digital data services over a communications link, interface, or other communications channel or line, which may be either wired, wireless, or a combination of both. The DDS controller 124 may include a housing configured to house digital media converters (DMCs) 126 to interface to a DDS switch 127 to support and provide digital data services. For example, the DDS switch 127 could be an Ethernet switch. The DDS switch 127 may be configured to provide Gigabit (Gb) Ethernet digital data service as an example. The DMCs 126 are configured to convert electrical digital signals to optical digital signals, and vice versa. The DMCs 126 may be configured for plug and play installation (i.e., installation and operability without user configuration required) into the DDS controller 124. For example, the DMCs 126 may include Ethernet input connectors or adapters (e.g., RJ-45) and optical fiber output connectors or adapters (e.g., LC, SC, ST, MTP).
