Abstract

The invention relates to a tearing and biting resisting optical cable and a preparation method thereof. The optical cable comprises a sheath 1. A sheath II is sleeved by the sheath I. A hollow structure is formed in the sheath II and at least one loose sleeve is arranged in the sheath II. At least 2n fibers are arranged in each loose sleeve, wherein n is a positive integer and 1<=n<=6. The preparation method comprises steps of S1, preprocessing of fiber cores; S2, forming of the sheaths; S3, cooling of cables; and S4, wire withdrawing of finished products. According to the invention, the optical cable is advantaged by big tensile modulus, high tearing resisting performance and tearing and biting resisting ability.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a tear-resistant optical cable and a preparation method thereof. Background technique [0002] Optical fiber, referred to as optical fiber, is a light transmission tool that transmits light on the principle of total reflection in fibers made of glass or plastic. The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Typically, a transmitting device at one end of the fiber uses a light-emitting diode or a laser to transmit light pulses into the fiber, and a receiving device at the other end of the fiber uses a photosensitive component to detect the pulses. Cables that contain optical fibers are called fiber optic cables. Because the transmission loss of light in optical fibers is much lower than that of electricity in wires, and because the main raw material is silicon, which has a huge reserve and is easy to mine, it i...
