Publication number: 20200153167Abstract: 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: ApplicationFiled: November 4, 2019Publication date: May 14, 2020Inventors: David Patrick Murray, Bernard Harold Hammond, JR.

Patent number: 10545296Abstract: A connector including two connector portions each including a ferrule and a latch, each latch including a distal end, and a proximal end, wherein the latch is pivotable about an intermediate connection portion; and a boot mounted to the connector portions, the boot movable longitudinally relative to the connector portions, wherein the boot causes the distal ends of the latch to pivot toward the ferrule of each connector portion as the boot is moved away from the connector portions. Front housings of the connector portions can each be rotated about the longitudinal axis of the ferrule without rotating the ferrule or the boot, to change the polarity of the two connector portions. The spacing between the two ferrules is adjustable. A holder holds the connector portions, the holder including side slots, the connector portions mounted to the holder by moving laterally to the side slots. The holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot.Type: GrantFiled: August 21, 2018Date of Patent: January 28, 2020Assignees: CommScope Connectivity UK Limited, CommScope Telecommunications (Shanghai) Co., Ltd.Inventors: David Patrick Murray, Chris Charles Taylor, Gordon John White, Zhaoyang Tong, Lei Liu
