Title:
OPTICAL CABLE, RIP CORD DISLODGEMENT METHOD, AND OPTICAL FIBRE EXPOSURE METHOD
Document Type and Number:
WIPO Patent Application WO/2023/167093
Kind Code:
A1
Abstract:
This optical cable comprises: an optical fibre; a sheath which protects the optical fibre; and a rip cord which is located at a part of the circumference of the sheath and at least a part of which is embedded in the sheath in a manner so as to be exposed from the inner surface of the sheath. The optical cable is configured such that the rip cord is dislodged to the inner side of the sheath when a side pressure load that is greater than the withstand load of the optical cable during use is applied from the inner surface of the sheath in the exposure direction in which the rip cord is exposed from the sheath, as seen from the centre of the rip cord, in a cross-section orthogonal to the longitudinal direction of the sheath 3.
