Abstract
A distributed sensing optical fiber cable is proposed. An optical fiber is positioned at the center of the cable and includes a core region, at least one cladding layer surrounding the core region, a protective coating covering the at least one cladding layer, and a tight buffer of elastomeric thermoplastic material disposed to surround the protective coating. The remainder of the cable structure includes a pair of strength members disposed longitudinally on either side of the optical fiber (the strength members formed of a glass-based, memory-less material) and a hard plastic jacket formed to encase the optical fiber and the pair of strength members, the plastic jacket preferably exhibiting an essentially rectangular profile.
