Abstract
A method and apparatus for a seismic cable is described. In one embodiment, the seismic cable includes a first cable segment and a second cable segment coupled together by a connector. Each cable segment includes an inner jacket defining a hollow core, a braided strength fiber surrounding the inner jacket, and an outer jacket circumferentially surrounding the braided strength fiber, wherein the connector isolates the first and second cable segments.
