摘要：An optical fiber cable for towing. An elongated central conductor includes a plurality of spiral grooves in the outer periphery thereof. Optical fibers are mounted within each of these grooves by use of a waterproof compound. An insulating layer covers the central conductor and the optical fibers. An outer conductor formed by a plurality of strands of conducting wire are wound about this insulating layer. A composite tape formed of a copper tape and an insulating tape is then wound about the outer conductor. The copper tape portion of the composite tape is in contact with the wire which forms the outer conductor. An armor layer of wire is wound about this entire structure. This arrangement provides an optical fiber cable with improved strength, ease of manufacture, and improved electromagnetic shielding.
