💬 Frequently Asked Questions
Q
What is the maximum temperature rating for this fiber optic cable?
This fiber optic cable is rated for a maximum operating temperature of 150°C (300°F), making it suitable for high-temperature environments such as industrial, downhole, and oilfield applications.
Q
What is the cable breaking strength and safe working tension?
The cable has a breaking strength of 25 kN (5,600 lbs). The maximum suggested working tension is 12.5 kN (2,800 lbs), which is 50% of the breaking strength, ensuring a safe operational margin during deployment.
Q
What fiber types are available and what are their attenuation values?
The cable supports both single-mode and multi-mode fibers. Single-mode fiber offers attenuation of 0.40 dB/km at 1310 nm and 0.30 dB/km at 1550 nm. Multi-mode fiber provides 3.5 dB/km at 850 nm and 1.2 dB/km at 1300 nm.
Q
What are the dimensions and weight of this fiber optic cable?
The cable has an outer diameter of 5.6 mm ± 0.20 mm (0.220″ ± 0.0078″) and weighs 152 kg/km (102 lbs/kft) in air. Its compact profile makes it well-suited for wireline and slickline deployment in space-constrained applications.
Q
What is the minimum shave (sheave) diameter for this cable?
The minimum sheave diameter for this cable is 600 mm (23.6″). Using sheaves smaller than this specification may damage the armor layers or the internal fiber optic unit and should be strictly avoided during installation and operation.
Q
How is the armor construction designed to protect the fiber optic unit?
The cable features a dual-layer armor design. The inner armor layer consists of 12 wires × 0.79 mm providing 916 N of protection, while the outer armor layer uses 18 wires × 0.79 mm for additional mechanical strength. This construction effectively protects the fiber optic unit tube against crush, tension, and abrasion forces encountered in downhole environments.
