    ❓ Frequently Asked Questions
    Q What is the maximum operating temperature for this cable?
    This cable is rated for a maximum temperature of 150°C (300°F), making it suitable for high-temperature downhole and industrial environments where standard cables may fail.
    Q What is the cable breaking strength and safe working tension?
    The cable has a breaking strength of 70 kN (15,750 lbs). The maximum suggested working tension is 35 kN (7,875 lbs), which is 50% of the breaking strength to ensure a safe operating margin.
    Q What fiber types does this cable support, and what are their attenuation values?
    The cable supports both single-mode and multi-mode fibers. Single-mode attenuation is 0.60 dB/km @1310nm and 0.40 dB/km @1550nm. Multi-mode attenuation is 3.5 dB/km @850nm and 1.2 dB/km @1300nm.
    Q What is the minimum shave diameter for this cable?
    The minimum shave (sheave) diameter is 800 mm (31.5″). Using a sheave smaller than this minimum can cause mechanical stress on the cable, potentially damaging the armor or optical fibers inside.
    Q What is the outer cable diameter and weight in air?
    The cable has an outer diameter of 11×22 mm (±0.50 mm), which is 0.433″×0.866″ (±0.0197″). Its weight in air is 667 kg/km (448 lbs/kft), important for calculating load capacity during deployment.
    Q What is the role of the steel strand and PP protection in the cable construction?
    The 7×2.0 mm steel strand provides tensile strength and mechanical protection against pulling forces during installation and operation. The 11×11 mm PP (polypropylene) protection serves as an outer protective layer, shielding the cable from abrasion, moisture, and environmental damage.
