Abstract
An optical fiber cable with optical fiber sensing and communication functions includes an outer sheath layer, an inner sheath layer, communicating optical fibers, and sensing optical fibers. The communicating optical fibers are laid inside the inner sheath layer, the sensing optical fibers are laid between the inner sheath layer and the outer sheath layer, and an inner reinforcing member is filled in the inner sheath layer. An outer reinforcing member-is filled between the inner sheath layer and the outer sheath layer, and a plurality of cutting kerfs for slotting are provided on an outer side wall of the outer sheath layer along a length direction of the outer sheath layer. A manufacturing method includes processes of cable paying-off, molding, extruding to form sheath layers, making cutting kerfs, cooling and cable taking-up, etc., which has simple operation and low production costs.
