    Frequently Asked Questions
    Q What is the maximum operating temperature of this fiber optic cable?
    This cable has a temperature rating of 150°C (300°F), making it suitable for high-temperature downhole and industrial environments where standard cables would fail.
    Q What is the cable breaking strength and recommended working tension?
    The cable has a breaking strength of 45 kN (10,000 lbs). The maximum suggested working tension is 22.5 kN (5,000 lbs), which is 50% of the breaking strength, ensuring a safe operational margin.
    Q What fiber optic attenuation values can I expect at common wavelengths?
    For single-mode fiber, attenuation is 0.40 dB/km at 1310nm and 0.30 dB/km at 1550nm. For multi-mode fiber, attenuation is 3.5 dB/km at 850nm and 1.2 dB/km at 1300nm, ensuring reliable signal transmission over long distances.
    Q What is the voltage rating and insulation resistance of this cable?
    The cable is rated at 1200 VDC with an insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), providing excellent electrical isolation suitable for demanding downhole power and data transmission applications.
    Q What is the overall cable diameter and weight?
    The overall cable diameter is 8.0 mm ± 0.10 mm (0.314″ ± 0.0039″). The cable weight in air is 290 kg/km (195 lbs/kft), offering a compact and manageable profile for deployment in tight wellbore environments.
    Q What is the minimum shave diameter and how does the armor construction protect the cable?
    The minimum shave diameter is 600 mm (23.6″). The double-armor construction features an inner armor of 18×0.81 mm wires (963N) and an outer armor of 18×1.11 mm wires (1808N), providing robust mechanical protection against crush, abrasion, and tensile loads during deployment and retrieval.
