Abstract

A seismic cable (110) and a method for producing a seismic cable are disclosed. The seismic cable (110) comprises a sensor module (130); at least one lead (210) to or from the sensor module (130); a stress member (225) extending continuously through the sensor module (130); and a sheath (230) enclosing the leads (210) and the stress member (225), the sheath (230) terminating at each end of the sensor module (130), and at least one mechanical guide (240) in the sensor module (130) deflecting the stress member (230). The method comprises providing a cable core including a stress member (225) and a lead (210); enclosing the cable core in a sheath (230); providing an opening in the sheath (230); and assembling a sensor module (130) to the cable core over the opening such that the stress member (225) extends continuously through the sensor module (130).
