A MULTI PURPOSE FIBER-OPTIC CABLE

摘要

A multipurpose optical cable is provided to be used in a complex net structure by installing a collected optical fiber and a loose tube having an optical fiber inside the optical cable which is previously installed. A multipurpose optical cable includes a central tension wire(1), a loose tube(3), an installation tube(5), an optical fiber retractable wire(6), an outer winding tape(7), a waterproof agent(4), and a rib cord(9). The central tension wire is located on the inner central part of the multipurpose optical cable. The loose tube is arranged along the circumference of the central tension wire. A ribbon optical fiber having a jelly is received inside the loose tube. The installation tube is arranged along the circumference of the central tension wire and maintains an original shape of the cable. The optical fiber retractable wire retracts a collected optical fiber and a small loose tube in the installation tube for a simple installation on the same route.
