Problems solved by technology

In addition, in order to meet the moisture-proof and water-proof performance of the optical cable, waterproof materials must be wrapped or filled around the optical fiber, so the manufacturing process is complicated, the cable diameter is large, the texture is heavy, the radius of curvature is large, the cost is expensive, and it is filled with waterproof ointment Easy to cause secondary pollution to the environment

Embodiment 1

[0007] Embodiment 1: refer to figure 1 . According to the existing thermosetting and thermoplastic composite pultrusion technology, wrapping a reinforcing sheath on an optical fiber and wrapping a protective sheath outside the reinforcing sheath, and because the reinforcing sheath is made of fiber-reinforced plastic, the optical cable referred to in the present invention can be obtained.

Embodiment 2

[0008] Embodiment 2: refer to figure 2 . According to the existing thermosetting and thermoplastic composite pultrusion technology, two (including more than two) optical fibers are respectively wrapped with a reinforcing sleeve and a protective sleeve is wrapped outside the reinforcing sleeve, and because the reinforcing sleeve is made of fiber-reinforced plastic, the invention can be obtained. called fiber optic cable.

Embodiment 3

[0009] Example 3: Take 13-25 kg of photocurable resin and 75-87 kg of fiber yarn, first put the photocurable resin into a constant temperature box at 70-90°C for 1-2 hours, then put the photocurable resin and fiber yarn into the solution Mix evenly in the tank, pultrude through a pultrusion die to form a shaped rod, place the shaped rod in an ultraviolet curing oven for 0.1 to 12 seconds to cure, and the fiber reinforced plastic referred to in the present invention can be obtained. In this embodiment, 20kg of photocurable resin and 80kg of fiber yarn are preferred. The photocurable resin is placed in a constant temperature box and the constant temperature is 80°C, and the constant temperature time is 1.5 hours. The curing time of the forming rod in the ultraviolet curing furnace is preferentially selected. 6 seconds.

Abstract

The invention relates to an optical fiber used in an outdoor system and an indoor system of a fiber-to-the-x (FTTx) network project in a communication network, fiber reinforced plastics used by the optical cable and a preparation method of the fiber reinforced plastics. As for the optical cable, at least one optical fiber is coated with a reinforced sheath which is the fiber reinforced plastics and is externally coated with a protecting jacket. The fiber reinforced plastics comprise the following components in parts by weight: 13-25 parts of light-cured resin and 75-87 parts of fiber yarn. The preparation method of the fiber reinforced plastics has the following steps: a, placing the light-cured resin in a constant temperature cabinet at the temperature of 70-90 DEG C for 1-2h; b, placing the light-cured resin and the fibre yarn in a solution tank for evenly mixing; c, pulling and extruding into a formed rod piece by a pultrusion module; and d, placing the formed rod piece in an ultraviolet curing oven for curing for 0.3-12s. The invention improves the safety protection performance of communication facilities and user terminal equipment; and the optical cable with fine diameter and small radium of curvature can satisfy the special requirements of easy branching, easy access and convenient construction in the FTTx network project.

Description

technical field [0001] The invention relates to a communication material, in particular to an optical cable of an outdoor system and an indoor system of an optical fiber access (FTTx) network engineering in a communication network, a fiber reinforced plastic used for the optical cable and a preparation method of the fiber reinforced plastic. Background technique [0002] At present, the optical cables for transmitting communication signals mainly use quartz glass optical fibers, and all of them adopt the reinforcement measures of coating resin on the surface of bare fibers. Since the material of the resin coated on the surface of the bare fiber has a defect of very low tensile strength, in order to improve the tensile strength of the optical cable, several strengthening members are added around the optical fiber. In addition, in order to meet the moisture-proof and water-proof performance of the optical cable, waterproof materials must be wrapped or filled around the optical...
