A communication module includes a wiring board including ground wiring, an electronic component provided on the wiring board, and a first connector provided on the wiring board and electrically connected to the electronic component via the wiring board. The first connector includes a metal member electrically connected to the ground wiring, and a plurality of pins arranged in an arrangement direction and including a plurality of high-frequency signal pins used for transmission of a high-frequency signal and a plurality of non-high-frequency signal pins for a use different from the transmission of the high-frequency signal. The plurality of high-frequency signal pins include a plurality of first pins successively arranged in the arrangement direction. None of the plurality of non-high-frequency signal pins is interposed between the plurality of first pins and the metal member.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A wire tracing system includes a voltage output source having a director circuit with a plurality of output channels. Each of the output channels outputs a unique voltage signature. A voltage reader/data recorder includes a conductive probe and a data memory that is partitioned into a plurality of data bins. Each of the data bins in the voltage reader/data recorder is associated with one of the voltage signatures output via the output channels of the director circuit, and each of the data bins is configured to store information associated with each of a plurality of wires to which the output channels are respectively connectable. The system and method permit a single individual to rapidly discover the identities of individual wires and cables without having to repeatedly travel back and forth between those extremities.
