Abstract: A system for transmitting video signals from multiple video cameras over one or more multiple pair, twisted pair cables includes several video cameras and a plurality of twisted pair- to-coax balun "T" devices connected to the video cameras by coaxial cables. The video cameras generate unbalanced video signals. The twisted pair-to-coax balun "T" devices are connected together in a "daisy chain" fashion by electrical cables having multiple twisted pairs of wires. The balun "T" devices convert the unbalanced video signals from the cameras to balanced video signals. The balanced video signals are transmitted over the multiple pair, twisted pair cables to a hub, which provides the video signals to one or more monitors, a DVR, a multiplexer or other device.

Abstract: A longitudinal balance measuring bridge circuit includes a common mode signal injection circuit in the form of a center tapped, 4:1 balanced matching transformer. The signal injection circuit is coupleable to an item under test (IUT) and to a source of common mode signal, and provides the common mode signal to the IUT. The common mode signal injection circuit includes balanced outputs. A common mode filter is coupled to the balanced outputs of the common mode signal injection circuit and attenuates the common mode signal. The common mode filter also includes balanced outputs on which are provided a transverse signal resulting from the common mode signal provided to the IUT. A signal output balun is coupled to the balanced outputs of the common mode filter and converts the transverse signal to an unbalanced signal.

Abstract: A connector module (1) permits termination of cross-connect wires (15) on one a front surface (4) and cable wires (21) on an opposite surface. The module exhibits a configuration, which permits test access and protector mounting from the front surface. The jumper wires (7) are inserted from a side surface through wire guides (22) or channels that bring the wires from the side surface to the front surface where the wires can be terminated without impeding insertion and removal of protection modules (8) from the front of the connector module. There is an intermediate surface below the front surface that is accessible from the front and recessed to allow protection modules to be installed completely below the terminated wires, allowing termination and maintenance of jumper wires after the protection module is installed from the front.

Abstract: A means and method for routing and managing buffered tube type fiber optical cable, particularly outside plant cable to an optical fiber cabinet or similar structure. The disclosure describes novel clamping elements (21-22) engaging the outside plant cable (12) which serve to separate the contained optical fibers (16), for guidance in individual paths to a point of connection, and provide a mounting point at the clamping elements prior to separation. The clamping elements (21-22) are transparent, enabling inspection and identification of individual fiber circuits (16).
