Enhanced fiber unit and manufacturing method thereof

Abstract

The invention provides an enhanced fiber unit and a manufacturing method thereof, relating to a fiber unit with an enhanced component and the manufacturing method thereof, and being suitable for production and manufacturing of various photoelectricity compound cables, optical fiber composite cables, seabed photoelectricity compound cables, indoor type optical cables and the like. The fiber unit comprises a plurality of optical fibers, optical fiber filling oil paste, an optical fiber protective layer, a fiber reinforced layer and a reinforced external sheath, wherein the outside of the optical fiber is coated with the optical fiber protective layer; the optical fiber filling oil paste is filled among a plurality of optical fibers in the optical fiber protective layer; the fiber reinforced layer is arranged outside the optical fiber protective layer; and the reinforced external sheath is arranged outside the fiber reinforced layer. The manufacturing method comprises the following steps: emitting the optical fiber from a constant tension dereeler, after forming beams, a layer of optical fiber protective layer is extruded out through a specific extruder; filling water repellent filler between the optical fibers when the optical fiber protective layer is extruded; and winding a layer of nonmetal fiber yarn with high strength outside the optical fiber protective layer, and extruding a layer of waterproof reinforced external sheath outside the fiber yarn, and obtaining a finished product.

Description

technical field [0001] The invention relates to an enhanced optical fiber unit and a manufacturing method thereof, which relate to an optical fiber unit with a reinforcing element and a manufacturing method thereof, and are applicable to various photoelectric composite cables, optical fiber composite cables, submarine photoelectric composite cables, and household-type optical cables Production and manufacture of fiber optic units such as power cables containing fiber optic units. The load-bearing element in the fiber unit is used to protect the fiber from being damaged by external forces such as tension and pressure, and to maintain the normal operation of the fiber. The optical fiber in the optical fiber unit can realize various information transmission and automatic control functions. Background technique [0002] In recent years, with the rapid development of my country's power grid construction, the power optical fiber used for power information transmission and control...
