Abstract:
1. A method of conducting a seismic survey, comprising: synchronizing a plurality of seismic devices over a fiber optic network using a recovered master clock signal, wherein at least one of the seismic devices is separated from a master clock by at least one other of the seismic devices, wherein the master clock and the plurality of seismic devices are arranged in at least one of: (i) a linear topology and (ii) a tree topology; encoding the master clock signal in a data stream along with at least one of i) a signal containing seismic data, and 2) a signal containing command and control information, the data stream comprising at least one of a 4B5B bit stream and a 8B10B bit stream; transmitting the data stream directly to one of the at least one other of the seismic devices; and propagating the master clock signal to the at least one of the seismic devices through subsequent seismic devices of the at least one other of the seismic devices by performing at each subsequent seismic device: transmitting the data stream directly to at least one subsequent seismic devices.
