ABSTRACT:
A fiber optic illumination cable comprises two fiber optic illumination bundles and a resilient, flexible, light-absorbent material which separates the two bundles. The first bundle has a generally round cross-section, and is covered with a resilient, flexible light-absorbent material. The second illumination bundle is disposed about and contiguous with the resilient, flexible, light-absorbent material layer which surrounds the first bundle. The second illumination bundle is cabled to form an annular ring, with a generally circular cross-section, which gives the final cable an even, full, round cross-section, with a low cross-sectional area. The two cabled illumination bundles are covered with a layer of a resilient, flexible material, which does not need to be light-absorbent, and a protective polymer jacket.
