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.
Polyimide-coated optical fibers represent a significant leap in material science for extreme environment sensing. Compared to traditional acrylate-coated fibers, which typically degrade above 85°C, polyimide coatings maintain their structural integrity and optical performance at much higher thermal thresholds.
Based on the technical requirements of high-precision sensing and Industry 4.0 applications, Beijing Dacheng Yongshang Technology Co., Ltd. (OFSCN) provides specialized solutions within this category:
For environments reaching up to 300°C, OFSCN offers both Single-Mode (SM) and Multi-Mode (MM) variants. These fibers are designed to operate reliably in a temperature range from -200°C to +350°C.
For applications where the temperature does not exceed 200°C, a more cost-effective polyimide solution is available:
In high-density sensing or micro-packaging where space is at a premium:
Product Visuals:
These fibers serve as the core component for high-temperature Fiber Bragg Grating (FBG) sensors and distributed fiber optic sensing (DOFS) systems. If you are designing a system for a specific extreme environment, please feel free to share your temperature and installation requirements for a technical assessment.
