Optical cable, a method of laying an optical cable, and a data transfer system using the optical cable

摘要

In an optical cable, at least one optical fiber is enclosed in a cover. The cover has an outer surface which in cross-section is in the shape of a trapezium formed by removing the right-angled isosceles corner region from a right-angled isosceles triangle. The optical cable can be installed running along a corner with its two perpendicular side faces lying against the surfaces which define the corner. Alternatively, the cable can be installed on a flat surface with the wider of the mutually parallel faces lying against the flat surface.
