This application relates to a submarine optical cable and its manufacturing method. Multiple stranded optical units and stranded reinforcing members are in contact with the outer surface of a central optical unit and are stranded around the central optical unit to form a cable core. Two stranded reinforcing members and one stranded optical unit form a clearance groove on the outer surface of the cable core. The outer surface of the stranded optical unit is the bottom of the clearance groove. This clearance groove in the cable core indicates a certain gap between the stranded reinforcing members and the stranded optical units, providing the stranded reinforcing members with sufficient tensile strength to prevent the optical units from breaking during the stranding process. It also prevents direct contact with water-blocking tape and copper tubing during subsequent production, reducing optical unit deformation and meeting the production requirements of water-blocking tape-wrapped submarine cables and submarine cables with conductive conductors. Furthermore, the stranding method of multiple stranded optical units and one central optical unit can meet the requirement of placing multiple optical fibers in a single submarine cable, facilitating subsequent splicing without damaging the spliced ​​optical fibers and reducing attenuation.
