Telenco designs and mass-produces a complete range of optical drop cables for telecoms operators and installers. Technical standards are evolving, and the specific requirements of Telenco's customers are very different. In this dynamic and varied commercial environment, the Group is able to adapt. One-stop sourcing solutions for fiber optic cables extrusion lines, including loose tube, tight buffer and cable sheathing processes. Features precision temperature control and laser measurement for micron-level accuracy, suitable for ADSS, OPGW and standard telecommunication cables. Fiber optic technology has revolutionized. The cable extrusion process can be defined as the primary manufacturing process associated with insulated cables and wires. It incorporates the continuous application of pressure and heat to mold the polymer into a form that can insulate dielectric material around a conductive core.
