Fiberhome Communications has beenGranted an Invention patent: "A Submarine Optical Cable and Its Manufacturing Method"

It is about Submarine Optical Cables and their manufacturing methods, multiple twisted optical units and twisted reinforcing parts all come into contact with the outer surface of the central optical unit and are twisted around the central optical unit to form the cable core.

Two stranded reinforcing pieces and one stranded optical unit form a avoidance groove located on the outer surface of the cable core. The outer surface of the twisted optical unit is the bottom of the avoidance groove. T

he avoidance groove of the above cable core indicates that there is a certain gap between the twisted reinforcing piece and the twisted optical unit, which enables the twisted reinforcing piece to provide a certain tensile strength, preventing the optical unit from being pulled apart during the twisting production process.

Additionally, it also avoids direct contact with the water-blocking belt and copper pipe during subsequent production, reducing the deformation of the optical unit. To meet the production demands of water-blocking wrapped submarine cables and submarine cables with conductors.

Furthermore, the above-mentioned stranding method of multiple twisted optical units and one central optical unit can meet the requirement of placing various Optical Fibers in a single submarine cable, and also facilitate the subsequent connection during use, without causing damage to the connected optical fibers and reducing attenuation.
