Communication optical fiber cable with armor system

Abstract

The invention relates to a communication optical fiber cable with an armor system. Hinge pieces are integrally formed on the two sides of an energy absorption cavity, inner cavity holes are formed inone ends of the hinge pieces, bump-shaped short rods are arranged at the other ends of the hinge pieces, and the bump-shaped short rods are matched with the hole grooves. Inner clamping cavities are formed in the centers of the tops of the hinge pieces, and clamping bump positions are arranged on one sides of the hole grooves. Male and female strips are formed by note-shaped sleeve plates and wavegrooves. Two opposite male and female buckles are embedded into each other to form male and female bases. Shaft nail rod holes are transversely formed in the front ends of the note-shaped sleeve plates, and shaft nail rods penetrate through the shaft nail rod holes. Armor box strips, the male base and the female base form armor strips. 2-4 armor strips are sequentially stacked up and down to forman armor piece. The armor piece is wrapped with a fireproof material film. The technical scheme is different from a traditional scheme in which armor is not provided at the optical fiber connecting position, various impacts during construction are absorbed through the structure of the energy absorption box, and the extra anti-pressure capacity in the later cable laying process is achieved.

Description

technical field [0001] The invention relates to a communication optical fiber cable of an armor system. Background technique [0002] According to the market research and forecast company IDC, the number of optical fiber access users in China will exceed 26.6 million in 2022, maintaining a compound annual growth rate of 56.4% in the next five years, and China has become one of the largest optical network equipment markets in the world. Optical fibers are composed of two layers of glass with different refractive indices. The inner layer is an optical core with a diameter of several microns to tens of microns, and the outer layer has a diameter of 0.1-0.2 mm. Generally, the refractive index of the inner core glass is 1% larger than that of the outer glass. According to the principle of refraction and total reflection of light, when the angle at which the light hits the interface between the inner core and the outer layer is greater than the critical angle for total reflectio...

Problems solved by technology

The characteristics of the material are considered to be the essence of the situation. The general public understands that the great disadvantage of optical fiber cables is that they are not resistant to bending, that is, they are prone to brittle fractures under bending conditions, thus losing the function of signal transmission.
