Abstract:
The present invention relates to a tray for use in a subrack of a rack. The tray comprises a printed circuit board configured so that a plurality of connections can be made at a plurality of positions on the printed circuit board, each of the plurality of connections involving at least one connector positioned on a patch side of the plurality of positions and the least one connector having a device associated therewith in which information is stored. Either side of the positions can be used as the patch side, and the devices associated with the connectors involved in making the connections at the patch side can be read via the tray. The devices can be implemented using RFID tags or connection point identifier (CPID) storage devices. A subrack comprises a backplate and at least one tray, wherein the tray can be selectively attached and removed from the backplate.
Abstract:
A device and method are described for providing test access for checking a transmission line carrying at least a plurality of digital channels, the transmission line (8, 18) having a plurality of twisted pairs, the device being for use with a test head (20) for determining a quality of the transmission line. A connection matrix (30) is provided for switching one of a plurality of the twisted pairs to a test bus (32), and a high pass filter (24) is coupled for maintenance of the digital channels, wherein the high pass filter is located in the connection matrix.
Abstract:
An out of band communications apparatus (110) includes first and second data lines (112, 212, 312) arranged in a differential pair (114, 214). The data lines convey high speed data within a first frequency range (104) and out of band data within a second frequency range (102) that differs from the first frequency range. The apparatus also includes a band pass filter (128, 222, 223, 324) coupled to the first and second data lines. The filter only passes the out of band data and blocks the high speed data. The apparatus also includes a device (134, 220, 322, 168, 184) coupled to the band pass filter and configured to at least one of transmit and receive out of band data.
Abstract:
One embodiment is directed to a RFID reader comprising RFID reader electronics and a plurality of antennas coupled to the RFID reader electronics. The RFID reader electronics is configured to use each of the antennas to read a respective different type of RFID tag. Other embodiments are disclosed.
Abstract:
A fiber optic telecommunications device includes a telecommunications frame (302) defining a plurality of mounting locations, each for receiving a fiber optic module (300) and including electrical contacts (1210) for connection with conductive portions of the module (300), at least a portion of the frame (302) formed from a printed circuit board (1204) that relays information from the contacts (1210) to electrical components (1208) located on the frame (302). A fiber optic module (300) is mounted on a mounting location. The module (300) includes a rack mount portion (344), a center portion (340), and a main housing portion (342), the rack mount portion (344) stationarily coupled to the frame (302), the center portion (340) slidably coupled to the rack mount portion (344) along a sliding direction, and the main housing portion (342) slidably coupled to the center portion (340) along the sliding direction. The rack mount portion (344) includes the conductive portions, the main housing portion (342) includes fiber optic connection locations (346) for connecting cables routed through the frame (302), and the center portion (340) includes a radius limiter (460) for guiding cables between the main housing portion (342) and the frame (302) and further includes a latch (394, 396) for unlatching the center portion (340) for slidable movement, wherein movement of the center portion (340) relative to the rack mount portion (344) moves the main housing portion (342) relative to the frame (302) along the sliding direction.
Abstract:
One embodiment is directed to a patching system. The patching system comprises at least one port, the port having a first side and a second side. The patching system further comprises at least one coupling circuit. The coupling circuit comprises a pickup portion and a reader portion coupled to the pickup portion. The coupling circuit is configured so that the pickup portion is positioned near the second side of the port and the reader portion is positioned near the first side of the port. The coupling circuit is configured so that an RFID tag mounted to a cable attached to the second side of the port can be read from the first side of the port via the reader portion of the coupling circuit.
