Publication number: 20190025515Abstract: A cable sorting and fusion splicing system (100) and method for arranging a plurality of optical fibers (17) in a cable in a predetermined sequence for fusion splicing to a multi-fiber optical connector (42). The cable sorting device 1 automatically sorts a plurality of optical fibers, such as twelve, loosely contained within a cable jacket (20). The fibers (17) are sorted in a predetermined sequence and maintained in a linear arrangement. The linear arrangement of fibers (17) is utilized at a fusion splicing device (40) to fusion splice to a multi-fiber optical connector having a corresponding sequence of optical fibers which are respectively fusion spliced to the optical fibers (17) of the cable. The fusion splicing device (40) is a mass fusion splicer which splices all of the fibers simultaneously.Type: ApplicationFiled: August 26, 2016Publication date: January 24, 2019Applicant: CommScope Asia Holdings B.V.Inventors: Laurens Izaak VAN WUYCKHUYSE, Paul SCHNEIDER, Jan Willem RIETVELD

Patent number: 10162126Abstract: A multi-fiber connector (40) that promotes physical contact with a communicating multi-fiber connector. The multi-fiber connector (40) has a connector body (44) with a front end (47) and a back end (49). The multi-fiber connector (40) also includes a ferrule (10a, 10b) with optical contacts (20a, 20b) at a front end (14a, 14b). The ferrule (10a, 10b) is spring biased toward the front end (14a, 14b) of the connector body (44). The ferrule (10a, 10b) has a pair of alignment pin openings (30a, 30b) extending into the ferrule from a front end (14a, 14b). The ferrule (10b) also has a pair of alignment pins (22) mounted within the alignment pin openings (30a, 30b). The base ends of the alignment pins (22) have a different transverse cross-sectional shape than the alignment pin openings (30a, 30b). This difference in transverse cross-sectional shapes allows the alignment pins to pivot relative to the ferrule along a major axis of the ferrule.Type: GrantFiled: December 1, 2015Date of Patent: December 25, 2018Assignee: COMMSCOPE ASIA HOLDINGS B.V.Inventor: Jacob Arie Elenbaas
