Frequently Asked Questions
Q
What is the maximum temperature rating for this fiber optic cable?
This fiber optic cable has a temperature rating of 150°C (300°F), making it suitable for high-temperature environments such as downhole oil and gas applications or industrial monitoring systems.
Q
What is the cable breaking strength and recommended working tension?
The cable has a breaking strength of 4 kN (900 lbs). The maximum suggested working tension is 2 kN (450 lbs), which is 50% of the breaking strength to ensure a safe operational margin.
Q
What fiber types are supported and what are their attenuation values?
The cable supports both single-mode and multi-mode fibers. Single-mode attenuation is 0.40 dB/km at 1310 nm and 0.30 dB/km at 1550 nm. Multi-mode attenuation is 3.5 dB/km at 850 nm and 1.2 dB/km at 1300 nm.
Q
What is the outer diameter and weight of this cable?
The cable has an outer diameter of 3.20 mm ± 0.10 mm (0.126″ ± 0.0039″) and weighs 46 kg/km (31 lbs/kft) in air. Its compact and lightweight design makes it easy to deploy in space-constrained installations.
Q
What is the minimum shave diameter for this cable?
The minimum shave (sheave) diameter for this cable is 320 mm (12.6″). Maintaining this minimum bend radius during installation and deployment is critical to preserving the cable's structural integrity and optical performance.
Q
Why does this cable use a stainless steel outer tube construction?
The stainless steel outer tube provides robust mechanical protection for the inner fiber optic unit tube. It offers excellent resistance to crushing, abrasion, and harsh environmental conditions, making it ideal for demanding applications such as downhole sensing, geothermal monitoring, and industrial process control.
