A seismic cable for seismic prospection comprising sensors distributed along the seismic cable, data transmission lines extending along the full length of the seismic cable for conveying data signals issued from the sensors, controllers also distributed along the seismic cable and adapted for operating interface between the sensors and the data transmission lines, and power supplying lines for electrically supplying the controllers and the sensors, said seismic cable comprises X power supplying lines and Y data transmission lines, said X power supplying lines being alternately connected to one out of X successive controllers so that the Nth power supplying line is connected to a Nth controller as well as to any following controller modulo X, and each controller being adapted for applying on a power supplying line detected as defective the electrical tension provided by another power supplying line, while the Y data transmission lines are alternately connected to one out of Y successive controllers so that the Nth data transmission line is connected to a Nth controller as well as to any following controller modulo Y, and each controller being adapted to redirect towards at least one adjacent controller the data associated with a data transmission line when this data transmission line is detected as defective; characterized in that each controller comprises a main switch closed in normal operation so as to maintain continuity of a power supplying line (300 N) and which is opened when contrarily said power supplying line (300 N) is detected as defective upwards of said controller (100 N), and an auxiliary switch provided downstream said main switch and suitable to connect the defective power supplying line (300 N) with another active power supplying line (300 N+1) when the upwards part of a power supplying line (300 N) is detected as defective. said seismic cable comprises X power supplying lines and Y data transmission lines, said X power supplying lines being alternately connected to one out of X successive controllers so that the Nth power supplying line is connected to a Nth controller as well as to any following controller modulo X, and each controller being adapted for applying on a power supplying line detected as defective the electrical tension provided by another power supplying line, while the Y data transmission lines are alternately connected to one out of Y successive controllers so that the Nth data transmission line is connected to a Nth controller as well as to any following controller modulo Y, and each controller being adapted to redirect towards at least one adjacent controller the data associated with a data transmission line when this data transmission line is detected as defective; characterized in that each controller comprises a main switch closed in normal operation so as to maintain continuity of a power supplying line (300 N) and which is opened when contrarily said power supplying line (300 N) is detected as defective upwards of said controller (100 N), and an auxiliary switch provided downstream said main switch and suitable to connect the defective power supplying line (300 N) with another active power supplying line (300 N+1) when the upwards part of a power supplying line (300 N) is detected as defective.
