FIBER OPTIC CABLE USED FOR BLOWING INSTALLATION METHOD

摘要

PURPOSE: A fiber optic cable used for blowing installation method is provided to reduce a cost for raw materials by minimizing the outside diameter and the weight of the optical cable. CONSTITUTION: A fiber optic cable used for blowing installation method includes a central strength member(210), a plurality of loose tubes(240), an aramid yarn(250), and a cable outer jacket(260). The central strength member(210) is installed in a center of the optical cable. The loose tubes(240) are bonded along a circumference of the central strength member by a S-Z method. The loose tubes include a plurality of optical fibers, respectively. Each loose tube has the diameter of 1.8 to 2.0mm. The aramid yarn(250) is used for binding the loose tubes. The cable outer jacket(260) is formed on an outer surface of the optical cable to protect the inside of the optical cable from the external environment.
