I. Introduction: The Next-Generation Optical Fiber for Extreme Environments
In demanding applications such as aerospace, downhole oil and gas exploration, high-temperature sensing, and industrial process monitoring, the requirements for optical fibers extend beyond traditional communication performance. They face multiple challenges concerning temperature limits, mechanical strength, and compact size.
The OFSCN® 350℃ Grade Small Diameter Polyimide (PI) Coated Single-Mode Optical Fiber (Model: OFSCN-9/80/100-PI12) is a specialty fiber designed by Beijing Dacheng Yongsheng Technology (DCYS) to address these industry pain points. With its unique structure and material advantages, it stands as a key technology for overcoming the limitations of extreme environments.

II. Core Technical Parameters and Structural Analysis
This optical fiber integrates three core technical advantages: ultra-high temperature resistance, high mechanical strength, and small-diameter structure.
1. Extreme Temperature Performance (350℃)
|
Parameter |
Indicator |
Analysis of Advantage |
|
Operating Temperature Range |
-65℃ to +350℃ |
Far exceeding standard fibers (85℃), allowing stable operation in most high-temperature industrial environments. |
|
Coating Material |
Polyimide (PI) |
PI coating offers exceptional thermal stability and chemical resistance, ensuring the fiber does not char or peel at high temperatures. |
2. High Strength and Reliability Guarantee
|
Parameter |
Indicator |
Analysis of Advantage |
|
Proof Test Level |
100 kpsi |
High proof stress level (significantly higher than standard 50 kpsi or 75 kpsi), meaning the fiber has undergone rigorous mechanical screening during manufacturing. It possesses outstanding tensile and bending resistance, greatly reducing the risk of breakage during cabling and long-term use. |
|
Mechanical Stability |
High |
Even at the high temperature of 350℃, the PI coating maintains excellent adhesion, effectively protecting the silica structure from environmental stress. |
3. Small Diameter Single-Mode Structure
|
Structural Parameter |
Size (μm) |
Analysis of Advantage |
|
Core/Cladding/Coating |
9/80/100 |
The cladding diameter is only 80μm, and the coating diameter is 100μm. This small-diameter design saves approximately 36% of the cross-sectional area compared to conventional 125/250μm fibers, significantly increasing cabling density and flexibility in confined spaces (e.g., FIMT sensor tubes, aerospace harnesses). |
|
Fiber Type |
Single-Mode (SM) |
Ensures low attenuation, high bandwidth, and long-distance transmission capability, suitable for high-precision distributed sensing and long-haul communication. |
III. Optical Performance Overview
As a high-performance single-mode fiber, its optical specifications are equally impressive:
- Low Attenuation: @1310nm ≤0.8 dB/km; @1550nm ≤0.8 dB/km.
- Mode Field Diameter (MFD): 9.3 ± 0.75μm (@1310nm), offering good compatibility with standard G.652D fibers.
IV. Typical Application Scenarios
The OFSCN® 350℃ PI-SM fiber, with its unique combination of advantages, is the ideal choice for the following key sectors:
- Fiber Bragg Grating (FBG) Sensing: Suitable for high-temperature strain, temperature, and pressure sensors, such as those used in downhole oil and gas monitoring and geothermal energy exploration.
- Aerospace and Defense: Used in real-time monitoring systems for aircraft engines, spacecraft, and naval vessels that operate in high-heat and high-vibration environments.
- New Energy Vehicles (Battery Monitoring): Employed for temperature and strain sensing inside electric vehicle battery packs to ensure operational safety.
- Industrial High-Temperature Process Control: Integrated into furnaces, boilers, and heat treatment equipment for long-term, stable temperature and condition monitoring.
V. Conclusion: Guarantee of High Reliability
The OFSCN® High-Strength 100 kpsi! 350℃ Grade 9/80/100μm Polyimide Single-Mode Optical Fiber solves the reliability issues of traditional fibers in extreme temperature and space-constrained environments through its PI coating and high-strength proof test.
