Patent number: 10074938Abstract: Methods and systems for providing crosstalk compensation in a jack are disclosed. According to one method, the crosstalk compensation is adapted to compensate for undesired crosstalk generated at a capacitive coupling located at a plug inserted within the jack. The method includes positioning a first capacitive coupling a first time delay away from the capacitive coupling of the plug, the first capacitive coupling having a greater magnitude and an opposite polarity as compared to the capacitive coupling of the plug. The method also includes positioning a second capacitive coupling at a second time delay from the first capacitive coupling, the second time delay corresponding to an average time delay that optimizes near end crosstalk. The second capacitive coupling has generally the same overall magnitude but an opposite polarity as compared to the first capacitive coupling, and includes two capacitive elements spaced at different time delays from the first capacitive coupling.Type: GrantFiled: March 27, 2017Date of Patent: September 11, 2018Assignee: CommScope Technologies LLCInventors: David Patrick Murray, Bernard Harold Hammond, Jr.

Patent number: 10067301Abstract: A connector (10) includes two connector portions (12) and a boot (14). Each connector portion (12) includes a ferrule (78) and a latch (18). The latch (18) includes a distal end (24) and a proximal end (22). The latch (18) is pivotable about an intermediate connection portion (26). The boot (14) is mounted to the connector portions (12). The boot (14) moves longitudinally relative to the connector portions (12). The boot (14) causes the distal ends (24) of the latch (18) to pivot toward the ferrule (78) of each connector portion (12) as the boot (14) is moved away from the connector portions (12). Front housings (32) of the connector portions (12) can each be rotated about the longitudinal axis of the ferrule (78) without rotating the ferrule (78) or the boot (14), to change the polarity of the two connector portions (12). The spacing between the two ferrules (78) is adjustable. A holder (96) holds the connector portions (12). The holder (96) includes side slots (98).Type: GrantFiled: January 13, 2014Date of Patent: September 4, 2018Assignees: COMMSCOPE CONNECTIVITY UK LIMITED, ADC TELECOMMUNICATIONS (SHANGHAI) DISTRIBUTION CO., LTD.Inventors: David Patrick Murray, Chris Charles Taylor, Gordon John White, Zhaoyang Tong, Lei Liu
