Abstract:
A method, system and computer program product to adjust transfer rates on conductors in a multi-conductor cable comprising monitoring signals received on each conductor, determining a Signal to Noise Ratio (SNR) for each conductor and adjusting a transfer rate on one or more conductors based on the corresponding SNR. In an embodiment the multi-conductor cable is a twisted pair Ethernet cable. The method further comprises determining whether a conductor is transmitting at an optimal transfer rate as a function of its SNR, calculating an optimal transfer rate for each conductor as a function of its SNR and periodically measuring a change in SNR on each conductor. If the change in SNR is greater than a predetermined threshold, then the transfer rate is re-calculated for the conductors requiring transfer rate adjustment as a function of SNR.
Abstract:
A telecommunications patch panel is provided having a plurality of connector modules rotatably mounted to a frame member. Each connector module has a front face and an opposite facing rear face, and each front face includes a plurality of connector jacks. Each rear face includes a plurality of wire termination blocks. The wire termination blocks are electrically connected to the connector jacks. Each connector module is rotatable about a rotation axis relative to the frame member. A lock selectively locks each connector module to the frame member as desired. The connector jacks and the connector modules are arranged in linear arrays perpendicular to the axis of rotation.

Patch cords include a communications cable that has a first conductor and a second conductor that form a first differential pair, and a third conductor and a fourth conductor that form a second differential pair and a plug that is attached to the communications cable. The plug includes a housing that receives the communications cable, first through fourth plug contacts that are within the housing, and a printed circuit board. The printed circuit board includes first through fourth conductive paths that connect the respective first through fourth conductors to respective ones of the first through fourth plug contacts. The plug further includes a first conductive shield that extends above a top surface of the printed circuit board that is disposed between the first differential pair and the second differential pair.
Abstract:
A stacked connector component includes a housing, connectors at a front opening of the housing and arranged in a stacked formation within one or more columns, and a for and exposed at the connectors. The pins include high-speed pins routed within the housing to a bottom side thereof and low-speed pins routed within the housing to a back side or a top side thereof. A circuit board includes pin pads connectable to the pins and disposed on a substrate. The pin pads include high-speed signal pin pads for the high-speed signal pins. The substrate includes contiguous high-speed areas in which the high-speed signal pin pads for the high-speed pins are located, between which no pin pads are located.
Abstract:
An RJ-45 insertion and extraction tool is disclosed that allows a user to plug and unplug an RJ-45 connector from an RJ-45 socket in a quick and easy way that does not disturb other cables plugged into adjacent sockets.
Abstract:
The present invention generally relates to the field of network communications, and more specifically to networks for crosstalk reduction/compensation and communication connectors which employ such networks. In an embodiment, the present invention is an RJ45 jack with an orthogonal compensation network to meet CAT6A or higher performance standard. For the 3:6-4:5 wire-pair combination, the orthogonal compensation network begins in the jack nose (plug interface contact (PIC)) section, and utilizes a flexible printed circuit board in the nose section, split PIC contacts in the rear nose, and circuitry in the rigid printed circuit board to create the orthogonal compensation network.
Abstract:
A metallic contact for insertion into a modular telecommunications plug includes a generally planar body defining a top end, a bottom end, a front end, a rear end, and a length extending from the front end to the rear end. The bottom end is at least partially defined by a blade for piercing an insulation of a wire positioned within the plug. At least a portion of the top end is configured to electrically contact a conductor of a jack that receives the plug. The top end is defined at least in part by a first engagement surface that is separated from a second engagement surface by a notch. An uppermost portion of the first engagement surface defines a first push surface that is generally at the same height as a second push surface defined by an uppermost portion of the second engagement surface. The notch is defined by a front vertical wall spaced from a rear vertical wall, wherein the front vertical wall is positioned at a distance of at least half the length of the contact from the front end of the contact.
Abstract:
A receptacle block defines one or more sockets at which plugs may be received. Each socket contains a first set of contacts and a second set of contacts. Each socket also includes a sensing contact that interacts with the second set of contacts to close an electrical switch. For example, the sensing contact can interact with an arm extending from one of the contacts of the second set. Closure of the switch can be detected and interpreted to indicate that a plug has been received at the respective socket.
Abstract:
An electrical connector arrangement includes a storage device coupled to a connector housing. The storage device is configured to store physical layer information pertaining to the electrical connector arrangement. The storage device also has contacts that enable the physical layer information to be read from the storage device by a media reading interface. A connector assembly includes at least one receptacle assembly; a printed circuit board; and a media reading interface.
Abstract:
A modular jack includes an insulative housing, an oblique inner PCB mounted on the insulative housing, a number of mating contacts soldered to the top edge portion of the inner PCB, a number of footer pins soldered to the bottom edge portion of the inner PCB, and a number of POE leads soldered to the top edge portion. The contacts, footer pins, and POE leads are retained on the same piece insulative housing, thus omitting requirement of an insulative carrier and a process of assembling the footer pins and POE leads to the insulative carrier. Each of the contacts, footer pins, and POE leads has a connecting section extending along a same direction in order for the tail sections to be soldered on a same top face of the inner PCB by a one-time soldering process.
