Invest in Extremes: OFSCN® Polyimide Optical Fiber, Solving All Your Extreme Environment Data Challenges

In the era of Industry 4.0 and high-precision sensing, the fragility of traditional optical fibers in high-temperature, low-temperature, or high-pressure corrosive environments has become the biggest bottleneck for data acquisition and system reliability.

Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS) offers the OFSCN® 300°C Multimode (MM) Polyimide Optical Fiber, engineered specifically to solve these "extreme challenges." It is not just a fiber; it is your data lifeline in the most hostile environments.

Part One: Core Advantages and Extreme Performance (Addressing "Reliability" Concerns)

The primary concern for customers is whether the fiber can truly operate stably over the long term under extreme conditions. Our fiber offers the following core advantages:

1. Exceeding a 550°C Temperature Span

• Operating Range: The rated operating temperature range is -200°C to +350°C, far surpassing standard optical fibers (which typically top out at only 85°C).
• Temperature Stability: The polyimide coating will not carbonize, vaporize, or peel off like traditional coatings in high heat, ensuring that the fiber maintains its structural integrity and optical performance even at 300°C and above.
• Thermal Shock Resistance: The fiber can withstand rapid thermal cycling, effectively mitigating permanent optical performance drift caused by thermomechanical stress, making it suitable for industrial equipment with frequent start-stop cycles.

2. Polyimide Coating: The Shield for Extreme Environments

• Chemical Corrosion Resistance: Polyimide features excellent chemical resistance, allowing it to withstand corrosive gases common in oil and gas downhole environments, such as Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2), significantly extending its service life.
• High Mechanical Strength: The fiber's tensile strength is up to 100 kpsi. This not only helps resist tensile stress during complex cabling processes but, more critically, effectively counters creep and fatigue under high-temperature and high-pressure conditions, ensuring the fiber's long-term durability.

3. Stable Optical Performance

• Across the entire temperature range from -200°C to +350°C, the fiber maintains low attenuation levels (e.g., < 1.2 dB/km at 1310 nm). We guarantee that key metrics like the Numerical Aperture (NA) and attenuation indicators remain stable even at extreme temperatures, thereby ensuring the accuracy of data acquisition.

Part Two: Application Scenarios and Solutions (Addressing "Field Applicability" Concerns)

Our customers come from specific industries with critical reliability requirements. This fiber provides exclusive solutions tailored to the pain points of these fields:

Industry Sector	Customer Pain Point	OFSCN® Solution
Oil & Gas Downhole	Traditional fiber failure and hydrogen darkening due to high temperature, high pressure, and corrosive gases.	Optional Carbon Coating and highly corrosion-resistant polyimide coating effectively combat hydrogen darkening and H2S erosion, extending the deployment time of downhole sensors.
Aerospace & Defense	Extreme low temperature (-200°C), vacuum, and severe vibration demanding ultra-high reliability.	The broad temperature range and 100 kpsi high mechanical strength ensure stable data links during launch and space operation.
Industrial Processes	Precise temperature monitoring in environments above 300°C, such as furnaces, nuclear power plants, and heavy machinery.	The 350°C maximum rated operating temperature makes it an ideal component for Distributed Temperature Sensing (DTS) and Fiber Bragg Grating (FBG) sensors.
Cryogenic Research	Data transmission in ultra-low temperature environments like liquid nitrogen storage and superconducting material research.	Guarantees the flexibility of the coating at -200°C, preventing micro-bending loss or breakage caused by low-temperature embrittlement.

Part Three: Procurement and Customization Services (Addressing "Cost and Compatibility" Concerns)

Customers care whether the initial investment is worthwhile and how to integrate it into existing systems.

Cost-Benefit Analysis

While the initial cost of polyimide fiber may be slightly higher than standard fiber, it offers a significantly lower Life Cycle Cost (LCC).

• Reduced Maintenance: In hard-to-maintain environments like downhole wells or high-temperature furnaces, the fiber's ultra-long lifespan drastically reduces downtime and replacement frequency.
• Data Assurance: Avoiding the loss of critical data or system shutdowns due to fiber failure—a value far exceeding the material cost.

Specification Compatibility and Customization

OFSCN® polyimide fiber supports industry-standard Multimode (MM) configurations, including 50/125μm and 62.5/125μm core/cladding sizes, as well as step-index and graded-index profiles, ensuring compatibility with existing communication and sensing demodulation equipment.

Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS), as a professional manufacturer, can provide customized core diameters, Numerical Apertures (NA), and coating solutions based on your project requirements, including the carbon coating option, to ensure the fiber perfectly matches your specific application.
