Anti-twisting optical fiber cable

摘要

An optical fiber cable includes: an optical fiber core wire (11), a reinforcing member (12) selected from aromatic polyamide fiber (such as Kevlar) coaxially covering the optical fiber core wire (11), a left-turn spring coil (13) leftward helically wound and continuously coaxially wound around the reinforcing member (12), a right-turn spring coil (14) rightward helically wound and continuously coaxially wound the left-turn spring coil (13), and an insulator outer layer (15) selected from polyvinyl chloride polymer coaxially cladding the right-turn spring coil (14) to coaxially form an optical fiber cable for increasing anti-twisting property and other mechanical properties.
