Problems solved by technology

[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. It is widely used Applied in the communication industry, with the popularization and large-scale application of optical cables, there are also the following problems in practical applications: 1) The tensile strength of optical cables is poor and the service life is short; 2) The high temperature resistance and flame retardancy of optical cables 3) The bending radius of the optical cable is relatively large, the quality is heavy, the floor area is large, and the construction is inconvenient; 4) The cost of the optical cable is relatively high, which increases the cost of the enterprise, which is a common problem of optical cables in the prior art some phenomena

Embodiment 1

[0023] see figure 1 , a high-temperature-resistant miniature armored optical cable, the optical cable from the inside to the outside is an optical fiber 1, a sleeve 2, an engineering plastic wrapping tube or a steel tape wrapping armor tube 3, an aramid braided mesh or a steel wire braided mesh 4, and an outer The sheath 5, the optical fiber structure is a dry structure, and the engineering plastic wrapping tube is arranged in a spiral shape. The optical fiber is made of tensile optical fiber, the tensile strength of ordinary optical fiber is 40-50N, and the tensile strength of tensile optical fiber can reach 100N, so the service life of the optical cable can be greatly increased during use. Aramid braided mesh and steel wire braided mesh have good tensile strength, and armored tube optical cable wrapped with steel tape has good mechanical properties such as impact resistance and pressure measurement. The optical cable has an ingenious structural design, good tensile and pres...

Embodiment 2

[0025] see figure 1 , as an improvement of the present invention, the casing material is modified polypropylene, referred to as PP; the modified polypropylene is added with high temperature resistant resin, halogen-free flame retardant, wherein the proportion of high temperature resistant resin: 25% -50%; halogen-free flame retardant: 25%-50%; the modified PP has the characteristics of high temperature resistance and flame retardancy, so that the optical cable has high temperature resistance and high flame retardancy.

Embodiment 3

[0027] see figure 1 , as an improvement of the present invention, the engineering plastic wrapping pipe is made of polycarbonate, referred to as PC. PC is heat-resistant, impact-resistant, and flame-retardant, which makes the optical cable have stronger impact resistance and flame retardancy.
