  • Patent number: 10703601
    Abstract: Transformable cable reels, related assemblies and methods are disclosed. The transformable cable reels may be provided in a first reel configuration for spooling on cable to the transformable cable reel and to pay out the spooled cable from the transformable cable reel. Cable spooled on the transformable cable reel may be payed out during cable installations. The transformable cable reel may also be configured in a second reel configuration for storage of any excess cable after cable payout. As one non-limiting example, the volume of the cable reel may be less in the second reel configuration than in the first reel configuration so that less volume is required to store the transformable cable reel. Providing the transformable cable reel in the second reel configuration may make it more feasible to store the transformable cable reel in fiber optic equipment, and/or avoid storing excess cable removed from a cable reel.

  • Patent number: 10694519
    Abstract: Time-division duplexing (TDD) in distributed communications systems, including distributed antenna systems (DASs) is disclosed. In one embodiment, a control circuit is provided and configured to control the TDD transmit mode of a DAS to control the allocation of time slots for uplink and downlink communications signal distribution in respective uplink path(s) and downlink path(s). The control circuit includes separate power detectors configured to detect either a transmit power level in a downlink path or a receive power level in an uplink path. If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.

  • Patent number: 10680920
    Abstract: Embodiments of the disclosure relate to managing a communications system based on software defined networking (SDN) architecture. An SDN controller is provided in the communications system to manage a wireless distribution system (WDS) and a local area network (LAN) based on SDN architecture. The SDN controller is communicatively coupled to a WDS control system in the WDS and a LAN control system in the LAN via respective SDN control data plane interfaces (CDPIs). The SDN controller analyzes a WDS performance report and a LAN performance report and provides a WDS configuration instruction(s) and/or a LAN configuration instruction(s) to the WDS control system and/or the LAN control system to reconfigure a WDS element(s) and/or a LAN element(s) to improve quality-of-experiences (QoEs) of the communications system. Monitoring and optimizing the WDS and the LAN based on a unified software-based network management platform can improve performance at reduced operational costs and complexity.

  • Patent number: 10673529
    Abstract: Embodiments of the disclosure relate to a high-directivity directional coupler, and related methods and systems. The high-directivity directional coupler includes a first microstrip and a second microstrip disposed parallel to the first microstrip. The high-directivity directional coupler inherently generates an even mode current and an odd mode current in the second microstrip. The second microstrip provides a linear forward path for conveying the even mode current and a non-linear return path for conveying the odd mode current. The non-linear return path is longer than the linear forward path to compensate for phase velocity difference between the even mode current and the odd mode current. As a result, the odd mode current and the even mode current in the second microstrip can destructively cancel out each other, thus rendering high-directivity without compromising other performance aspects of the high-directivity directional coupler.
