Patent number: 10534151Abstract: A system forms, at an end of a multifiber ribbon cable, a multifiber ribbon cable segment having an enlarged core-to-core spacing. A UV-transparent mold is mounted on top of a chassis. The mold defines a plurality of individual fiber channels corresponding to individual fibers of the existing multifiber ribbon cable and having a spacing equal to that of the enlarged core-to-core spacing. Each individual fiber channel passes through the internal cavity. The assembled mold further includes an injection system for receiving light curable, flowable material from the reservoir and pumping system and feeding it into the internal cavity, and at least one vent for allowing air to escape from the internal cavity as the light-curable, flowable material is fed into the internal cavity. The injected material is cured by exposure to a curing light.Type: GrantFiled: November 3, 2017Date of Patent: January 14, 2020Assignee: OFS FITEL, LLCInventors: Denis E. Burek, Wladyslaw Czosnowski, Yue Liang

Patent number: 10502914Abstract: A telecommunication cabinet for managing connections between incoming and outgoing cables at building premises. The cabinet has a back wall, and bottom, top, left, and right walls. The bottom wall has a first incoming cable port that opens at a front edge of the bottom wall, the top wall has a second incoming cable port that opens at a front edge of the top wall, and the second incoming cable port is aligned vertically with the first incoming cable port. At least one of the right and the left walls has an outgoing cable port. Layers of incoming cables can enter the cabinet for connection, or pass through the cabinet to enter a second cabinet, by inserting the layers from the front of the cabinet into one or both of the incoming cable ports. Cable clamp assemblies fix the cables of each layer at corresponding positions inside the ports.Type: GrantFiled: September 28, 2017Date of Patent: December 10, 2019Assignee: OFS FITEL, LLCInventors: Xavier Chiron, Wladyslaw Czosnowski

Patent number: 9568684Abstract: A multicore fiber alignment apparatus is described, having a chassis into which is mounted ferrule-holding means for holding a multicore fiber ferrule having one or more capillaries extending therethrough. Fiber-holding means for holding one or more multicore fibers in position to be mounted into the ferrule, such that each multicore fiber extends through a respective ferrule capillary. Means are provided for monitoring the rotation angle of each multicore fiber within its respective capillary, relative to a reference rotational orientation. Means are further provided for rotating each of the multicore fibers within its respective capillary. The rotational orientation of each multicore fiber is fixed when its rotation angle is equal to zero.Type: GrantFiled: May 20, 2016Date of Patent: February 14, 2017Assignee: OFS Fitel, LLCInventors: Kelvin B Bradley, Wladyslaw Czosnowski, Tristan Kremp, Yue Liang

Patent number: 9366829Abstract: A ganged connector housing is configured to receive a plurality of single-fiber connectors. Each connector is removably retainable at a respective location in the connector housing. Each single-fiber connector comprises a ferrule configured to receive and retain a single multicore fiber. The single-fiber connectors have a high-density packing footprint within the connector housing. Each single-fiber connector and its respective ferrule is configured to enable individual repositioning, tuning, alignment, repair or replacement of a respective multicore fiber terminated therein, independent of other optical fibers within the plurality of single fiber ferrules, and without requiring replacement of the entire set of multicore fibers.Type: GrantFiled: May 24, 2013Date of Patent: June 14, 2016Assignee: OFS FITEL, LLCInventors: Wladyslaw Czosnowski, Gregory A.

Patent number: 9360634Abstract: An alignment block for aligning a multicore fiber has a body with a front face and a rear face, and includes a capillary extending between a front opening at the first face and a rear opening at the rear face. The capillary has an inner circumference that includes an alignment surface corresponding to the multicore fiber alignment surface. The front opening is shaped to fit closely around the multicore fiber so as to prevent non-longitudinal movement of the multicore fiber relative to the alignment block body. The rear opening is shaped to fit around the multicore fiber so as to allow a selected amount of non-longitudinal movement of the multicore fiber relative to the alignment block body. The capillary provides tapered transition between the rear opening and the front opening. Movement of the multicore fiber along the capillary causes the multicore fiber alignment surface to be urged against the capillary alignment surface so as to align the multicore fiber cores relative to the alignment block body.Type: GrantFiled: December 4, 2013Date of Patent: June 7, 2016Assignee: OFS FITEL, LLCInventors: Wladyslaw Czosnowski, John George
