Patent number: 10812664Abstract: A power transmission system includes a voltage measurement device located on a tower or rooftop for measuring a voltage (VRRH) at a top end of a DC cable connected to a remote radio head (RRH). A voltage control system receives an input voltage (VIN) from a DC power supply and generates an output voltage (VOUT) at a base end of the DC cable. The voltage control system calculates a voltage drop on the DC cable based on the VRRH measurement and then adds different voltage steps to VIN so VOUT compensates for the voltage drop. Calculating the voltage drop allows the PTS to more efficiently supply power to RRHs without having to increase the size of DC power cables.Type: GrantFiled: January 19, 2018Date of Patent: October 20, 2020Assignee: RAYCAP S.A.Inventors: Grigoris Kostakis, Anestis Kolovos, Nikolaol Tsakiridis, Michael C.

Patent number: 10802237Abstract: A fiber optic cable management system includes a tray configured to reciprocate inside of an enclosure between an inserted position and an extended position. Optical fiber modules are located in the tray and retain optical fiber splitters or optical fiber multiplexer/de-multiplexers. The tray when moved to the extended position moves the optical fiber modules out of the front end of the rack enclosure. This allows a technician to access the back of the modules for maintenance operations without having to access the back end of the enclosure. A flexible cable guide allows the optical fibers connected to the modules to move with the tray into and out of the enclosure. Reflectors can be attached to the connectors to test fiber optic lines between a central office and the cell site location.Type: GrantFiled: December 8, 2017Date of Patent: October 13, 2020Assignee: RAYCAP S.A.Inventors: Kostantinos Bakatsias, Charis Coletti, Andreas Vagenas, Cynthia Steele, Jonathan Martinez

Patent number: 10429604Abstract: An optical interface includes a rack mountable enclosure that includes multiple slots for retaining multiple insertable fiber optic (FO) modules. The FO modules include a first set of interconnection ports that connect to remote radio units (RRUs), a second set of interconnection ports that connect to a baseband unit (BBU), and a third set of monitoring ports that connect to monitoring/text equipment. The FO modules contain fiber splitters that split off uplink/receive and downlink/transmit signals carried on optical fibers to the third set of monitoring ports. The FO modules may insert in different orientations and directions into different rack mountable enclosure configurations for higher density and more configurable connectivity. A splitter holder is located within the FO module and provides improved optical fiber routing for more integrated module port interconnectivity.Type: GrantFiled: April 12, 2018Date of Patent: October 1, 2019Assignee: RAYCAP S.A.Inventors: Konstantinos Bakatsias, Elias Gonalakis, Charis Coletti, Eleni Dimou
