Special optical fiber
Face the core pain point: the dilemma of traditional optical fiber in extreme environments
In many cutting-edge technologies and industrial scenarios, environmental factors have become a key bottleneck restricting fiber performance:
High-temperature environment
For example, in aerospace engine monitoring, geothermal detection or metallurgical process control, Continuous high temperatures of hundreds of degrees will cause the aging and decomposition of ordinary optical fiber coatings. and change the core structure, resulting in a surge in signal loss and complete interruption of transmission.
Strong radiation environment
In nuclear power plant reactor monitoring, space satellite communication, and high-energy physics experimental equipment, the continuous bombardment of high-energy particles (such as γ rays and neutrons) will produce defects such as color centers in optical fiber materials, causing a "darkening" effect, causing the optical fiber transmittance to drop off a cliff and greatly shorten the life.Strong electromagnetic interference and complex stress environment
In power substations, near large electrical equipment, or in scenarios such as deep-sea high voltage and oil well exploration, Multiple factors, such as strong electromagnetic noise, continuous mechanical vibration, high voltage, and chemical corrosion, are intertwined.Posing a multi-dimensional threat to the physical integrity and signal purity of optical fibers.These pain points not only affect the real-time and accuracy of data but may also directly lead to the failure of critical systems, causing huge security risks and economic losses. Therefore, the development of special optical fibers that can stably adapt to extreme environments has become an urgent need in related industries.
Hirundo Solution: Escort the whole process from customization to validation. Hirundo believes that there is no "one-size-fits-all" fiber, only the "most suitable" solution. We move away from one-size-fits-all standard product thinking and provide end-to-end specialty fiber customization services from in-depth requirements analysis to final environmental validation.
- 1. Deep collaboration and precise definition of requirements
Our team of technical experts will work closely with you to understand your specific application scenario and environmental parameters (e.g., temperature range, radiation dose spectrum, stress type, etc.), and performance metrics (bandwidth, loss thresholds, mechanical strength, etc.). This stage is fundamental to ensure the success of the solution.
2. Customization of special materials and structures
For high-temperature scenarios, we use high-temperature-resistant specialty polymer coatings or even metal coatings instead of conventional acrylate coatings, and use doped optimized quartz substrates to ensure structurally stable and low-loss operation of fibers in extreme temperatures.In order to cope with strong radiation, we have developed irradiation-resistant fiber core materials. which greatly suppress radiation-induced losses and maintain long-term optical performance through selected doping elements (such as radiation-resistant cerium elements, etc.) and unique process treatment.
3. Multi-parameter collaborative optimization design
While meeting environmental tolerance, we use an advanced simulation design platform to synergistically optimize key optical and geometric parameters such as optical fiber dispersion characteristics, mode field diameter, bending loss, and cut-off wavelength. For example, design low-loss, large-effective area single-mode fiber for long-distance sensing; design special-structure optical fibers that suppress nonlinear effects for high-power transmission; Design the ultimate bend-resistant fiber for cabling in compact spaces.
4. Reliability verification in extreme environments
Each custom fiber must be tested in Hirundo's advanced extreme environment simulation chamber. We simulate real-world operating conditions and conduct long-term high-temperature cycling tests and irradiation-accelerated aging tests for specific energy spectrums. and mechanical reliability tests such as vibration, shock, and tensile forces, and provide detailed performance degradation data reports. Only products that pass the full set of validation schemes will be delivered to customers.
