Abstract
Disclosed is a loose tube optical cable having an unstranded structure, which includes a tensile strength member longitudinally elongated and having a central axis deviated from the center of the optical cable, a loose tube optical fiber unit longitudinally elongated without intended twist against the tensile strength wire, and a cable coating for wrapping an aggregation in which the tensile strength member and the loose tube optical fiber unit are straightly aggregated. By suitably selecting geometric parameters of the tensile strength member and the loose tube optical fiber unit, the center of mass of the aggregation is positioned within the tensile strength member and the maximum modulus of elongation of the optical fiber is restricted within a predetermined range in a predetermined bending radius.
