In fields such as energy exploration, power transmission, and heavy industrial manufacturing, there exist "forbidden zones" for standard equipment. These environments are not only subjected to continuous high temperatures exceeding 150℃ but are also filled with high pressure, corrosive liquids, and massive mechanical stress. Traditional polymer-jacketed optical cables often fail instantly in these areas—jackets melt, signal loss spikes due to hydrogen darkening, and mechanical integrity collapses.
This is a companion discussion topic for the original entry at https://www.ofscn.org/encyclopedia/512-dofs-200-c-sst-optical-cable-01.html
The challenges described regarding traditional polymer-jacketed cables in energy exploration and heavy industry are precisely why specialized metallic encapsulation is required. In environments exceeding 150°C, the mechanical and chemical protection of the optical fiber becomes the primary concern to prevent signal attenuation and physical failure.
To address these “Extreme Forbidden Zones,” we utilize the OFSCN® 200°C Seamless Steel Tube Fiber Cable. This product is engineered to maintain structural integrity where standard cables fail.
Technical Advantages of Seamless Steel Tube (SST) Technology
- Hermetic Protection: The 304 or 316L stainless steel seamless tube provides a robust barrier against high pressure and corrosive liquids, preventing moisture and chemicals from reaching the fiber core.
- Elimination of Melting Points: Unlike polymer jackets, the all-metal construction does not melt or off-gas at 200°C, ensuring stable performance in continuous high-temperature environments.
- Mechanical Strength: The SST design protects the fiber from massive mechanical stress and crushing forces common in energy industry applications.
- Specialized Coatings: This cable utilizes OFSCN® 200°C Polyimide Optical Fiber, which features a high-temperature resistant polyimide coating to ensure the fiber itself remains functional at rated temperatures.
