摘要： The present application relates to the field of optical cables, and specifically provides a flexible optical fiber ribbon and a ribbon optical cable. The flexible optical fiber ribbon includes a plurality of optical fibers arranged in parallel in a same plane to form an optical fiber arrangement, and connecting parts are arranged at an interval in a longitudinal direction of a front arrangement surface and a back arrangement surface of the optical fiber arrangement respectively; the connecting parts are straight shapes with a certain inclined angle and are unevenly distributed on the optical fiber arrangement; materials of a front surface connecting part and a back surface connecting part are a resin; a viscosity of the resin of the front surface connecting part is higher than that of the resin of the back surface connecting part, and a tensile strength of the resin of the front surface connecting part is higher than that of the resin of the back surface connecting part. The resins of the front surface connecting part and the back surface connecting part are different in tensile strength and adhesion degree, which is suitable for the situation that the optical fiber ribbon is coiled or folded to the back, so as to ensure that a bonding point of the optical fiber ribbon does not fall off during a process of coiling to result in optical fiber scattering.
