Problems solved by technology

[0003] The traditional radio frequency remote optical cable still has certain defects when used in outdoor projects. It does not have the function of preventing monkeys and rats from scratching and biting. The unique smell contained in the plastic is easy to attract rodents to bite. Monkeys in some mountainous areas are frequent, and they will also scratch and bite the optical cable and affect the quality of communication. In severe cases, it may even cause the interruption of the trunk communication network.
At the same time, most of the mobile base stations are built in positions with a wide view or high terrain, high open terrain or high terrain, high hillsides, and mountains. Lightning activities are extremely frequent. Due to frequent lightning activities, it is very important for the safe operation of base station equipment. a great potential threat

Embodiment 1

[0040] refer to figure 1 As shown, this embodiment discloses a rodent-proof, monkey-proof and lightning-proof radio frequency remote optical cable for a base station, which includes: an optical fiber 1, a PBT tight sleeve material 2 sleeved outside the optical fiber 1, Aramid fiber reinforcement 3, central sub-cable sheath layer 4, water blocking tape 5, steel tape armor layer 6, outer sheath layer 7.

[0041] In this embodiment, PBT is used as the tight sleeve layer for the optical fiber protective layer. PBT is polybutylene terephthalate. This material has strong tensile strength, bending strength, and impact strength, and is less affected by environmental changes. And other characteristics, compared with nylon material, the process performance is stronger, the processing temperature is wider, and the cost is lower.

[0042] The steel strip pattern longitudinal armoring enhances the tensile strength, compressive strength and anti-corrosion ability of the optical cable. When...

Embodiment 2

[0052] The structure of the optical cable in Example 2 is the same as that in Example 1, except that the PBT material includes: 80 parts of PBT, 20 parts of glass fiber, 6 parts of synergistic flame retardant system, and 10 parts of flame retardant and toughening system. parts, 1.5 parts of lubricants, 1.5 parts of dispersants, 0.8 parts of antioxidants, and 0.5 parts of antibacterial agents.

[0053] The synergistic flame retardant system includes polyphenylene sulfide and aluminum diethylphosphinate, and the mass fraction ratio of the polyphenylene sulfide and aluminum diethylphosphinate is 1.5:1.

[0054] The flame retardant and toughening system includes: 1 part of antimony trioxide, 0.2 part of sodium silicate, 2.5-4 parts of sodium bicarbonate, 0.8 part of POE, 0.1 part of calcium dodecylbenzenesulfonate, ethylene-acrylic acid methyl 1 part of ester-glycidyl methacrylate terpolymer.

Embodiment 3

[0056] The PBT tight sleeve material in this embodiment includes: 90 parts of PBT, 25 parts of glass fiber, 12 parts of synergistic flame retardant system, 15 parts of flame retardant and toughening system, 2 parts of lubricant, 2 parts of dispersant, 1 part of antioxidant part, 0.8 part of antibacterial agent.

[0057] The synergistic flame retardant system includes polyphenylene sulfide and aluminum diethylphosphinate, and the mass fraction ratio of the polyphenylene sulfide and aluminum diethylphosphinate is 1.5:1.

[0058] Specifically, in parts by weight, the flame retardant and toughening system includes: 1.5 parts of antimony trioxide, 0.4 parts of sodium silicate, 4 parts of sodium bicarbonate, 1.3 parts of POE, calcium dodecylbenzenesulfonate 0.8 parts, 3 parts of ethylene-methyl acrylate-glycidyl methacrylate terpolymer.

Abstract

The invention discloses a radio frequency remote optical cable for a ratproof and monkeyproof base station capable of conducting thunder and lightning. The optical cable successively comprises a tight tube optical fiber, an aramid fiber reinforcing piece, a waterproof band, a steel tape armoring layer and an outer protective layer from inside to outside, wherein the tight tube optical fiber comprises an optical fiber and a PBT tight material arranged on the outer side of the optical fiber, and the PBT tight material comprises 70-90 parts of PBT, 15-25 parts of glass fibers, 3-12 parts of a synergistic flame retardant system, 5-15 parts of a flame retardant toughening system, 0.5-2 parts of a lubricant, 1-2 parts of a dispersant, 0.5-1 part of an antioxidant and 0.1-0.8 part of an antibacterial agent. By means of a novel structural design and a process manufacturing method, stick grain longitudinal wrapping armoring of the steel tape enhances the tensile strength and compressive strength of the optical cable, and the erosion resistance is improved and the service life is prolonged. The radio frequency remote optical cable is a relatively good ratproof method, and as the tensile strength is enhanced, the optical fiber is prevented from breaking as monkeys climb and drag the optical cable.

Description

technical field [0001] The invention relates to the field of communication optical cables, in particular to a rodent-proof, monkey-proof and lightning-conductive radio-frequency remote optical cable for a base station and a preparation method thereof. Background technique [0002] With the development of the communication industry, the communication network has developed from a single voice service to a full-service integrated communication information network with voice, data, and video services. Access network development. Remote radio is a new type of distributed network coverage mode, which effectively solves many coverage problems caused by low operating frequency. One of the traditional radio remote optical cables is to directly cover the single-mode or multi-mode optical fiber with a nylon tight-sleeved material with high bonding strength to make a tight-sleeved optical fiber, and two single-mode or multi-mode tight-sleeved optical fibers are made of high-strength A...
