A fiber optic ribbon cable includes a jacket of the cable, the jacket having a cavity defined therein, an optical element including an optical fiber and extending within the cavity of the jacket, and a dry water-blocking element extending along the optical element within the cavity. The dry water-blocking element is wrapped around the optical element with at least a portion of the dry water-blocking element disposed between another portion of the dry water-blocking element and the optical element, thereby defining an overlapping portion of the dry water-blocking element. The optical element interfaces with the overlapping portion to provide direct or indirect coupling between the optical element and the jacket.

The assembly consists of at least one metal insert and one reinforcing sheet. The reinforcing sheet contains reinforcing fibers longer than or equal in length to one centimeter. The metal insert comprises protrusions shaped to traverse the sheet, passing between the reinforcing fibers, and to fold by plastic deformation, enclosing the reinforcing fibers when said protrusions are subjected to a longitudinal compression force.

Provided is a manufacturing method of a bending module that forms a plurality of joint members by press-processing sheet material, with each joint member having a joint member body, a connection protrusion and a wire guide protrusion having a wire guide hole formed at one side corner of the joint member body, and one connection protrusion is formed at another side corner of the joint member body. The wire guide protrusions are folded with respect to the joint member bodies; a joint member assembly is formed by arranging the plurality of joint members in parallel and connecting neighboring connection members to connect the joint members together; the joint member assembly are bent to a ring shape; and each joint member is connect to each other by welding corners thereof.
