Abstract
Disclosed herein is an optical cable comprising a plurality of cable sensors helically wound around a support; and an outer jacket that is disposed on the plurality of cable sensors and surrounds the plurality of cable sensors; where each cable sensor comprises an optical fiber; where the optical fiber comprises an optical core upon which is disposed a cladding; a primary coating; a deformable material surrounding the optical fiber; and an outer tube surrounding the deformable material; where the optical fiber is of equal length to the outer tube; and where an allowable strain on the optical cable with zero stress on the optical fiber is determined by equations (1) and (2) below: where d is the amount of optical fiber clearance for free movement within the loose tube, D is an average pitch diameter of the plurality of cable sensors and p is an average pitch length of a helical turn of the plurality of cable sensors wound around the central strength member.
