Background
The outer diameter of the indoor flexible optical cable for the general access network generally exceeds 2mm, which causes a certain space occupation ratio and has certain limitation in use. The currently available special optical cable with the smallest outer diameter should be an EPFU (reinforced optical fiber unit), and the optical cable can only be used under a special laying method (generally air-blown laying) due to the limitation of tensile strength.
The invention relates to a wire guidance optical cable which is developed according to the urgent need of the wire guidance use field and has the advantages of superfine outer diameter (0.25mm-0.45mm), ultrahigh tensile strength (8kg-15kg), excellent bending resistance (the minimum allowable bending radius is 5mm) and large length (10-100 km).
The prior optical cable technology, such as the Chinese invention patents with application numbers of 200710061570.1 and 02147221.1, all adopt loose structures for protecting optical fibers, and have essential differences from the present invention. Although the chinese utility model patent with application number 02206019.7 adopts the tight-buffered optical fiber (optical fiber direct sheathing) cabling method, the structure of the invention is greatly different from that of the invention, the invention adopts the method of tightly wrapping and covering the reinforcing yarn outside the optical fiber to enhance the tensile strength of the optical fiber, and the reinforcing elements mentioned in CN02206019.7 are arranged on both sides of the optical fiber and adopt the embedded method to provide the tensile strength.

According to the superfine, super-bending-resistant and super-strength guidance optical cable, the inner core of the optical cable adopts bending insensitive optical fibers, a reinforced yarn layer is coated around the optical fibers, and an outer coating layer is coated outside the reinforced yarn layer; the outer diameter of the optical cable is 0.25-0.45 mm, the tensile resistance is 8-15 kg, and the allowable minimum bending radius is 5 mm;
in one embodiment, the reinforcing yarn layer is 2-12 strands of reinforcing yarns, and the reinforcing yarns are soaked by polyester materials; the outer coating material is a polyester material, and the polyester material is cooled and solidified by water;
in another embodiment, the layer of reinforcing yarns is 2-12 strands of reinforcing yarns, which are impregnated with acrylate; the outer coating material is acrylate, and the acrylate is subjected to photocuring;
preferably, the number of strands of the reinforcing yarn depends on the linear density of the reinforcing yarn;
preferably, the optical cable satisfies a use environment of-60 ℃ to 85 ℃.
Preferably, the invention selects the bend insensitive fiber with the minimum bend radius of 7.5mm, or selects the bend insensitive fiber with the minimum bend radius of 5mm designed by a special fiber core;
preferably, the invention selects a plurality of strands of high-modulus aramid fibers or other high-modulus fibers (such as polyethylene high-strength fibers) as yarns, and the smaller the linear density of the fibers, the more guaranteed the performance of the final product;
preferably, the present invention selects a special polyester-based photo-curing material as the coating and bonding material.
