A method of manufacturing an optical fiber cable, the method comprising:
- unspooling an optical fiber;
- unspooling a first sheet of metal having a first upstream minor edge, a first downstream minor edge, and first opposing major edges, the first opposing major edges extending longitudinally along a length of the first sheet of metal between the first upstream minor edge and the first downstream minor edge, and the first upstream and first downstream minor edges extending laterally across a width of the first sheet of metal;
- unspooling a second sheet of metal having a second upstream minor edge, a second downstream minor edge, and second opposing major edges, the second opposing major edges extending longitudinally along a length of the second sheet of metal between the second upstream minor edge and the second downstream minor edge, and the second upstream and second downstream minor edges extending laterally across a width of the second sheet of metal;
- forming a reinforcement layer by welding the first sheet of metal to the second sheet of metal via a periphery of a welding unit along the first upstream minor edge of the first sheet of metal and the second downstream minor edge of the second sheet of metal at a single interface between the first sheet of metal and the second sheet of metal along a length of the reinforcement layer, wherein the periphery of the welding unit comprises a plurality of protrusions and a plurality of recesses between the plurality of protrusions;
- forming the reinforcement layer around the optical fiber;
- and
- extruding a polymer composition around the reinforcement layer to form a jacket.
