Abstract: The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes a multi-zone crosstalk compensation arrangement for reducing crosstalk at the jack.

Abstract: 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.

Abstract: A fiber optic cassette including a body defining a front and an opposite rear and an enclosed interior. A cable entry location is defined in the body for a cable to enter the interior of the cassette. The cable which enters at the cable entry location is attached to the cassette body and the fibers are extended into the cassette body and form terminations at connectors. The connectors are connected to adapters located at the front of the cassette. A front side of the adapters defines termination locations for cables to be connected to the fibers connected at the rear of the adapters. A cable including a jacket, a strength member, and fibers enters the cassette. The strength member is crimped to a crimp tube and is mounted to the cassette body, allowing the fibers to extend past the crimp tube into the interior of the cassette body. A strain relief boot is provided at the cable entry location.

Abstract: A telecommunications system (14) includes a chassis (12) defining a front (18), a rear (16), and a plurality of first signal connection locations (38) adjacent the rear (16). A plurality of removable cassettes (10) are housed within the chassis (12), each including a cassette body (68) defining a fixed portion (80) that is coupled to one of the first signal connection locations (38) on the chassis (12) and a movable portion (82) that telescopically slides relative to the fixed portion (80), wherein the movable portion (82) is configured for movement in a direction from the front (18) to the rear (16) of the chassis (12), each cassette (10) defining a plurality of second signal connection locations (58). A cable (24) between the fixed portion (80) and the movable portion (82) extends out from the movable portion (82) when that portion (82) is pulled forwardly to an extended position and is retracted into the cassette body (68) when the movable portion (82) is pushed rearwardly relative to the fixed portion (80).
