Abstract
Abstract A hybrid cable of substantially uniform cross section throughout its length for concurrently carrying optical signals and electrical signals. The cable includes a high strength central section and a section surrounding the central section and including a plurality of electrical conductors. The central section includes a pair of high strength members engaging one another with each having a metallic core and a resilient sleeve. The central section further includes at least one optical conductor having an optically conductive core and a resilient sleeve with the optical conductor engaging both of the strength members and extending substantially to the periphery of the central section. Geophones can be connected to the electrical conductors at spaced locations intermediate the ends of the cable without interference with components of the central section.
