Patent number: 10567974Abstract: 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.Type: GrantFiled: April 12, 2019Date of Patent: February 18, 2020Assignee: Corning Optical Communications LLCInventors: Igor Berlin, Moshe Daniel, Yoni Henia, Rami Reuven, Motti Yakobi

Patent number: 10291323Abstract: Components, systems, and methods for determining efficiency of an optical signal source in distributed communication systems are disclosed. Environmentally induced variations in the performance of optical sources used to convert electrical signals to optical signals (such as laser diodes) at the transmitters within the system can be evaluated in real time. Steps can be taken to compensate for these variations. The efficiency of the laser diode can be measured and provided to receivers in the distributed communication system. The receiver may use information related to the slope efficiency measurement to adjust the gain of the receiving amplifiers to provide desired adjustments to the gain. Thus, the receivers in the remote units (RU) receive information about the slope efficiency of the laser diodes at the head end equipment (HEE) and the HEE receives information about the slope efficiency of the laser diodes at the RU.Type: GrantFiled: April 27, 2018Date of Patent: May 14, 2019Assignee: Corning Optical Communications LLCInventors: Ofer Nisan, Rami Reuven, Pinhas Yehuda Rosenfelder, Ofer Shinaar

Publication number: 20180083673Abstract: A method and system for supporting M1MO technologies which can require the transport of multiple spatial streams on a traditional Distributed Antenna System (DAS). According to the invention, at one end of the DAS, each spatial stream is shifted in frequency to a pre-assigned band (such as a band at a frequency lower than the native frequency) that does not overlap the band assigned to other spatial streams (or the band of any other services being carried by the DAS). Each of the spatial streams can be combined and transmitted as a combined signal over a common coaxial cable. At the other “end” of the DAS, the different streams are shifted back to their original (overlapping) frequencies but retain their individual “identities” by being radiated through physically separate antenna elements.Type: ApplicationFiled: September 21, 2016Publication date: March 22, 2018Inventors: Igor Berlin, Yair Oren, Rami Reuven, Ofer Saban, Isaac Shapira

Patent number: 9715157Abstract: A voltage controlled optical directional coupler (VCODC) having a coupling ratio that can be adjusted to any desired value through voltage tuning is disclosed. The VCODC may include a first optical hybrid coupler and a second optical hybrid coupler, which may be coupled with each other via one or more voltage controlled optical elements having a variable transparency depending on a voltage applied to the one or more voltage controlled optical elements. The VCODC may be configured to divert a portion of optical power received to a trunk input of the VCODC to a tap output of the VCODC based on the variable coupling ratio of the VCODC, which may be dependent on the variable transparency of the one or more voltage controlled optical elements.Type: GrantFiled: December 8, 2015Date of Patent: July 25, 2017Assignee: Corning Optical Communications Wireless LtdInventor: Rami Reuven

Patent number: 9548708Abstract: Variable power ratio (VPR) directional couplers that permit an amount of power directed to different outputs to be varied and managed. In some embodiments, the power ratio of the VPR coupler is represented by an equivalent coupling factor C? corresponding to a conventional coupling factor C. The VPR coupler may include one or more variable reactive network (VRN) circuits, each configured to reflect a portion of power received from an input back toward the input, and to transmit a remainder of the power toward an output. An amount of power reflected and transmitted by the VRN circuit may be varied based on a control voltage applied to the VRN circuit. In one example, a plurality of VPR couplers can be arranged in series to create a versatile and simplified network for distributing signals to a plurality of end units.Type: GrantFiled: August 11, 2015Date of Patent: January 17, 2017Assignee: Corning Optical Communications Wireless LtdInventor: Rami Reuven
