A system and process for preparing high temperature resistant onboard optical cable

Abstract

The application discloses a system and process for preparing high-temperature-resistant airborne optical cable, and belongs to the technical field of special optical cable forming. The structure of the buffer layer forming mechanism is optimally designed, and a combination of a variable-diameter needle tube and a first extrusion device is used, so that the first buffer layer formed by a film-shaped material belt and the second buffer layer formed by extrusion of the extrusion material can be formed synchronously on the outer periphery of the optical fiber during the forming and preparation of the airborne optical cable. A double-layer buffer layer structure with hard outer layer and soft inner layer is obtained, and a high-temperature-resistant airborne optical cable with excellent structural performance is prepared. The system and process for preparing high-temperature-resistant airborne optical cable have simple system structure and convenient process steps, can quickly realize the forming and preparation of the high-temperature-resistant airborne optical cable, and ensure that the prepared airborne optical cable can meet the high-temperature-resistant requirement, effectively improve the degree of freedom of the optical fiber, reduce the additional attenuation of the optical fiber caused by stress, and improve the performance stability and use convenience of the optical cable.
