MGTS33-8B1 Mining Armor Communication Optical Cable Technical Analysis
I. Structure and Materials
Fiber Configuration: 8-core single-mode fiber (G.652.D standard), utilizing a loose-tube stranded structure, with water-resistant grease in the loose tubes to ensure full cross-sectional performance.
Enhanced Design: Phosphate-coated steel wire reinforced core (diameter ≥ 1.2mm), tensile strength ≥ 1500N, dynamic bending radius ≥ 20 times the outer diameter.
Protective Coating:
Inner sleeve: Made of PE material, waterproof and moisture-proof.
Outer sheath: Blue flame-retardant PVC (Oxygen Index ≥ 28), meets the mining standards of MT/T 1009-2020.
II. Key Performance
Flame Retardancy: Self-extinguishing time upon bundle combustion ≤ 30 seconds, halogen-free with low smoke (transmittance ≥ 60%).
Mechanical Strength: Double zinc-coated steel wire armor, side pressure resistance ≥ 3000N/100mm, rodent-proof design.
Transmission Performance: Supports 10Gbps high-speed transmission with attenuation ≤0.36dB/km (at 1310nm wavelength).
