  • Patent number: 10520693
    Abstract: A pre-mounted fiber optic distribution cabinet assembly is disclosed. The pre-mounted fiber optic distribution cabinet assembly includes a fiber optic distribution cabinet with an enclosure having an interior configured to house fiber optic components. The fiber optic distribution cabinet is sealed to protect against the ingress of solid foreign objects and liquids into the interior. A frame attaches to the exterior of the enclosure so that the fiber optic distribution cabinet is mounted in the frame when shipped to an installation location. The fiber optic distribution cabinet is configured to be mounted at the installation location via the frame. A stabilizer attached to the fiber optic distribution cabinet provides balancing support to the fiber optic distribution cabinet to maintain the fiber optic distribution cabinet in a generally upright orientation with the frame attached to the fiber optic distribution cabinet.

  • Patent number: 10523222
    Abstract: A phase locked loop (PLL) provides output signals at multiple frequencies. In particular, the PLL includes a phase detector and two voltage controlled oscillators (VCOs). One of the VCOs is selectively enabled depending on a desired output signal. The phase detector receives a reference signal and a feedback signal from the enabled one of the two VCOs. The phase detector outputs a control signal that controls the VCO that provided the feedback signal.

  • Patent number: 10524133
    Abstract: One embodiment of the disclosure relates to radio frequency (RF) communication channel reconfiguration in remote antenna unit (RAU) coverage areas in a distributed antenna system (DAS) to reduce RF interferences. In this regard, a spectrum optimization unit dynamically reconfigures RF communication channels employed by RAU coverage areas in a DAS to reduce or avoid adjacent-channel and/or co-channel RF interferences. Each of the RAU coverage areas provides a respective sniffed RF signal to the spectrum optimization unit. The spectrum optimization unit analyzes the respective sniffed RF signal to determine a respective lesser-interfered RF communication channel for an RAU coverage area and dynamically reconfigures the RAU coverage area to communicate on the respective lesser-interfered RF communication channel.

  • Patent number: 10523327
    Abstract: Embodiments of the disclosure relate to digital-analog interface modules (DAIMs) for flexibly distributing digital and/or analog communications signals in wide-area analog distributed antenna systems (DASs). In this regard, in one aspect, a DAIM is a multi-functional device capable of distributing the digital and/or analog communications signals to a local-area DASs in a wide-area DAS. The DAIM comprises an analog radio frequency (RF) communications signal interface for coupling with an analog signal source, a digital communications interface for coupling with a digital signal source, an analog local distribution interface for coupling with a remote antenna unit (RAU), and at least one digital remote distribution interface for coupling with a head-end unit (HEU) of the local-area DAS. By employing the DAIM in the wide-area DAS, it is possible to flexibly reconfigure the wide-area DAS for distributing digital and/or analog communications signals over the digital communications mediums.

  • Patent number: 10516434
    Abstract: A communication circuit in a wireless communications system (WCS) is provided. The WCS employs self-interference cancellation (SIC) circuitry to suppress an interference signal(s) associated with an uplink communications signal(s) in a target uplink band(s). A communication circuit is employed to provide more accurate temporal and phase estimates about interference signal(s) in the target uplink band(s). The communication circuit utilizes an anchor downlink signal, which can be any of the downlink communications signals communicated in the WCS, to help determine an optimal phase shift for uplink communications signal(s) in the target uplink band(s). Accordingly, the SIC circuitry can suppress the interference signal(s) in the target uplink band(s) based on the optimal phase shift.

  • Patent number: 10517004
    Abstract: Application modules (AMs) with multi-carrier subscriber identity modules (MSIMs) for diagnostic mode monitoring of signals within wireless distributed communications systems (WDCSs), including but not limited to distributed antenna systems (DASs). Related systems and methods are also disclosed. The MSIMs comprise circuitry configured to implement multiple SIM instances, each SIM instance containing carrier-specific data to enable the AM to register with a carrier to perform diagnostic mode monitoring of signals from the respective carrier. In one embodiment, AMs may be associated with components of a WDCS. By associating the AMs into components of a WDCS, live signals in the WDCS can be monitored and measured for monitoring the performance of components within the WDCS. The AMs may include one or more application level applications configured to receive and monitor signals in the WDCS, and to provide application-level information about such monitored signals to other components or systems, or technicians.

  • Patent number: 10514506
    Abstract: An optical coupler that provides evanescent optical coupling includes an optical fiber and a waveguide. The optical fiber has a glass core, a glass inner cladding surrounding the glass core, and a polymeric outer cladding surrounding the glass inner cladding. The glass core and glass inner cladding define for the fiber a glass portion, which can be exposed at one end of the fiber by removing a portion of the polymeric outer cladding. The glass portion has a glass-portion surface. The waveguide has a waveguide core and a surface, and can be part of a photonic device. The glass portion of the fiber is interfaced with the waveguide to establish evanescent coupling between the fiber and the waveguide. Alignment features are used to facilitate aligning the fiber core to the waveguide core during the interfacing process to ensure suitable efficiency of the evanescent coupling.
