Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head-end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired.

An adapter for electrically connecting a laser diode to a circuit board is disclosed. An example laser diode may form part of an optical communications system in which the laser diode emits optical signals into an optical fiber cable based on electrical signals received from one or more source circuits. The laser diode is electrically connected to the source circuit(s) through a circuit board. A laser diode adapter is provided to facilitate electrically connecting, as well as mechanically coupling, the laser diode to the circuit board. In this regard, the laser diode adapter includes conductive pads for coupling to conductive legs of the laser diode. The laser diode adapter also includes a set of conductive signal pads for coupling to conductive receiving pads which are electrically connected to the conductive pads, thereby electrically connecting the conductive legs of the laser diode to the circuit board.

Embodiments of the disclosure relate to reducing power consumption in a remote unit of a wireless distribution system (WDS) for intermodulation product suppression. Intermodulation products generated by a power amplifier circuit can leak from a downlink signal path into an uplink signal path to degrade sensitivity of the uplink signal path in a remote unit. In this regard, the remote unit is configured to measure a power of the leaked intermodulation products and enables a selected number of power amplifiers in the power amplifier circuit for reducing the measured power of the leaked intermodulation products to a predetermined threshold. By enabling only the selected number of power amplifiers based on the measured power of the leaked intermodulation products, it is possible to avoid enabling an excessive number of power amplifiers in the power amplifier circuit, thus helping to reduce power consumption for intermodulation product suppression.

Methods and systems for reducing leaked downlink interference signals in a remote unit uplink path(s) in a distributed antenna system (DAS) are provided. In a remote antenna unit (RAU) disclosed herein, a downlink interference signal may be leaked from a downlink path to an uplink path in the RAU. In this regard, an adjustment circuit is provided in the downlink path of the RAU to suppress the downlink interference signal. A control system is provided in the DAS to monitor the leaked downlink interference signal and control the adjustment circuit in the RAU to minimize the leaked downlink interference signal in the uplink path. By providing the adjustment circuit in the RAU and the control system in the DAS to minimize the leaked downlink interference signal in the uplink path, it is possible to reduce interferences between downlink and uplink communications signals without increasing costs of the RAU.
