Delving to the Earth’s Core: OFSCN® Specialty Fiber Optic Patch Cord — Triple Protection Against High Pressure, High Temperature, and Severe Corrosion

In deep engineering fields such as oil and gas, geothermal exploration, and other subsurface applications, equipment must not only withstand temperatures reaching 300 degrees or higher, but also simultaneously combat fluid pressures of several thousand PSI and the erosion of corrosive agents like hydrogen sulfide (H2S). Failure in any single component can lead to project downtime and significant financial loss.

Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS)’s OFSCN® Specialty Fiber Optic Patch Cord Series is specifically engineered to meet this triple threat challenge of high pressure, high temperature, and severe corrosion. We establish an impenetrable defense barrier through unique all-metal encapsulation and specialty fiber technology.

Challenge 1: High Temperature (300 Degrees+) — The Polyimide Core Guarantee

The heat resistance of the optical fiber is foundational. Our patch cord utilizes a Polyimide coated fiber as its core, ensuring:

• Sustained Temperature Resistance: The Polyimide coating can withstand continuous operating temperatures of 300 degrees or higher, far exceeding the 80 degree limit of standard fibers.
• Optical Stability: Under high temperatures, the Polyimide coating does not carbonize or decompose, maintaining the fiber's low attenuation and long-term stability.

Challenge 2: High Pressure (Thousands of PSI) — The Sealing Power of Stainless Steel Seamless Tubing

In downhole, high-pressure reactors, or deep-sea environments, pressure resistance and hermetic sealing are crucial.

• Precision Seamless Tubing: The OFSCN® patch cord uses Stainless Steel Seamless Steel Tubing for its armor, rather than conventional loose tube or stranded structures. This seamless design is key to achieving high-pressure sealing.
• Physical Barrier: The steel tube forms a robust and sealed pressure vessel, completely isolating the internal optical fiber from the external high-pressure fluid. It is capable of withstanding high hydrostatic or fluid pressure, protecting the fiber from crushing deformation and ensuring signal integrity.

Challenge 3: Severe Corrosion (H2S, Saltwater) — The Chemical Resistance of 316L Steel

In highly corrosive environments, even at temperatures of 300 degrees, corrosive media can penetrate materials.

• Preferred 316L Stainless Steel: The armor of our specialty fiber optic patch cords primarily uses 316L stainless steel (or other high-corrosion-resistant alloys upon request). 316L steel contains molybdenum, giving it superior resistance to pitting and crevice corrosion compared to ordinary stainless steel, particularly in environments rich in Hydrogen Sulfide (H2S) and saltwater common in the petroleum industry.
• All-Metal Encapsulation: Combining the seamless steel tube structure with our proprietary epoxy-free high-temperature connectors, the entire link forms an all-metal, highly chemically resistant encapsulation system.

Conclusion: True Industrial-Grade Protection

The OFSCN® Specialty Fiber Optic Patch Cord is not just a "high-temperature cable"; it is a comprehensive engineering solution for extreme environments. By cleverly combining Polyimide fiber, 316L grade seamless tubing, and proprietary 300 degree connection technology, it achieves:

Dimension	Solution	Advantage
High Temperature	Polyimide Coated Fiber	Long-term stable operation above 300 degrees
High Pressure	Stainless Steel Seamless Tubing	Hermetic isolation, withstands immense fluid pressure
Severe Corrosion	316L Steel Armor	Resists chemical attack from H2S, saltwater, etc.

Choose OFSCN® to empower your critical equipment and sensors to delve to the Earth's core, fearless against the challenges, ensuring stable and secure data transmission.
