Abstract
A distributed geophone data acquisition system is disclosed that includes a receiver for the geophone data and a plurality of data cables connected together and to the receiver at one end. The cables have a plurality of twisted pairs of electrical conductor channels and two fiber optic light guides. Multiple geophone takeouts are connected to separate channels of the cables. Remote data units are connected between adjacent ends of each data cable that convert the geophone signals on each channel to light signals for transmitting through the fiber optic light guide of the next cable to the next remote data unit and ultimately to the receiver.
