ABSTRACT:
A data signal transmission cable particularly adapted for use in seismic prospecting permits high speed digital data transmission. In a preferred embodiment, the cable includes a transceiver at each end and two repeaters located near the center of the cable for differentiating and retransmitting signals transmitted from respective ends to opposite respective ends. Each repeater is energized from the end from which it receives transmitted data. A preferred method permits communicating seismic data signals over two serial pairs of twisted metallic wires.
