High-temperature resistant fiber faces specific challenges in various aspects when operating in high-temperature environments, commonly used in sensing, LDI, and other fields. In high-temperature conditions, conventional fibers often experience problems such as optical loss, refractive index changes, and material expansion. Here are four key challenges:

Material Selection: High-temperature resistant fiber requires the use of materials with excellent high-temperature stability, such as special glasses or ceramic materials. Selecting suitable materials needs to consider factors such as chemical stability, thermal expansion coefficient, and tensile strength under high-temperature conditions.

Structural Design: The structure of high-temperature resistant fiber needs to withstand the stress and deformation caused by high temperatures. Fiber design should balance strength, flexibility, and thermal stability to ensure the fiber does not fracture or lose performance in high-temperature environments.

Fiber Connection and Packaging: In high-temperature environments, fiber connections and packaging must maintain stable optical transmission performance. This includes selecting fiber connectors, connection techniques, and packaging materials that can maintain good connection quality and low losses under high temperatures.

Environmental Adaptability: High-temperature resistant fiber also needs to adapt to different high-temperature environmental conditions, such as industrial furnaces, high-temperature air, or high-pressure environments in aerospace applications. The high-temperature performance of the fiber requires rigorous testing and validation to ensure its stability and reliability.

Hecho's self-developed high-temperature resistant fiber offers advantages such as high-temperature resistant interfaces, high power handling, high transmittance, long-term high transmittance retention, aging-resistant sheathing options, high-temperature packaging, ultra-long lifespan, and high beam collimation.

Fiber optic gyro, or FOG, is a high precision instrument using optical fiber technology. It works intuitively, like "dancing" light in a fiber.

When light travels through the fiber, the propagation path in it also changes if the fiber rotates. By accurately measuring this change, the optical fiber gyro can calculate the rotation speed and direction of the optical fiber.

The key of fiber optic gyro lies in its high-precision optical system and electronic signal processing system. The optical system ensures that the light travels stably through the optical fiber, while the electronic system is responsible for receiving and processing the optical signals to obtain accurate angular velocity data. Due to its high sensitivity, rapid response and long-term stability, FFG has been widely used in aviation, aerospace, navigation and other fields, providing an important means of angular velocity measurement for navigation and control systems.

The research team at NASA's Armstrong Flight Research Center has made a breakthrough in developing a technology called a "fiber-optic sensing system."The core is to use the optical fiber as a sensing element to realize the real-time monitoring and data feedback of the structural strain, shape, temperature and other key parameters by capturing the physical characteristic changes when the optical waves are transmitted in the optical fiber.

 Optical fiber sensing system shows great potential in the field of aircraft research with its high sensitivity, strong anti-interference ability and excellent stability. It can accurately capture the tiny deformation and temperature fluctuations of the structure in a complex environment, providing rich and accurate data support for designers, and greatly improve the research accuracy and design efficiency.

Its high-precision and long-distance sensing capabilities give it promising prospects in construction, Bridges, energy and other fields. With the continuous progress of technology, optical fiber optic sensing systems will play a key role in more fields to promote the technological innovation and development of related industries.

It is well known that the optical fiber in the general sense is composed of a fiber core, cladding layer and coating layer. Among them, the fiber core, cladding determine its optical characteristics, generally with molten quartz in the environment of 2000℃ pull down, high temperature performance naturally need not say much. In the process of quartz glass pull, its surface will inevitably leave subtle cracks, used by a kinds of environmental stress, crack may rapidly expand and even break, so in the first time to help it put on a layer of sheath —— coating layer, to greatly improve its mechanical characteristics, make it more bending more tensile.

It is understood that at domestic and foreign, the application scenario of high temperature resistant optical fiber is very wide. In the exploitation of oil and natural gas, the oil well temperature measuring optical cable needs to be able to withstand the underground high temperature and high pressure environment, and then it is necessary to use the high temperature resistant optical fiber. In thermal power generation, the real-time monitoring of boiler temperature and pressure also requires the stable transmission of high-temperature resistant optical fiber. In addition, in the automotive industry, high-temperature resistant optical fibers are used in on-board communication and entertainment systems to ensure the stable transmission of information in high-temperature engine and exhaust system environments. In the field of aerospace, the high temperature resistance performance of communication equipment is extremely high. The application of high temperature resistance optical fiber can improve the reliability and stability of communication equipment in high temperature environment.

Polyimide (Polyimide, PI), with an excellent temperature range of-190℃ ~ + 385℃, has penetrated into every aspect of our lives since DuPont was first commoditized in 1961. For example, the flexible circuit board (FPC), often used in electronic products, is 280℃ lead-free welding and is made of polyimide; it is also made into fabric for firefighters, astronauts, and racers.

In theory, 385℃ is the upper temperature limit of the polyimide, regardless of higher temperatures. High temperature resistant metal coated fiber, by coating the surface of the bare fiber with a layer of high temperature resistant metal material, such as aluminum, copper or gold, to improve the performance of the fiber in high temperature environment. This fiber performs well at extreme temperature conditions and has excellent resistance to chemical corrosion and mechanical bending.

High temperature-resistant metal-coated optical fibers are widely used in areas that need to withstand high temperature and corrosive environments. For example, metal-coated optical fibers all play an important role in nuclear radiation, high-energy and strong laser transmission, welded fiber beams, and medical applications. In addition, in the field of high temperature sensing fiber, it can be used as turbine sensing fiber, oil and gas well fiber, engine sensing fiber, etc., to withstand the work demand in high temperature environment. Metal optical fibers are also often used as gas-tight optical fibers.

To handle the optical fiber end and linker grinding, need to rely on advanced technology equipment and exquisite technology. First of all, the high-precision grinder is used to grind the optical fiber end slightly to ensure the smooth and smooth end surface. 

Next, polishing is performed with specially designed polishing tools to eliminate subtle scratches and irregularities. For the linker, a special grinding and polishing process is used to ensure its accurate docking with the optical fiber end.

Throughout the process, the precise control system and on-line detection technology ensure that every step is accurate.

Holmium laser is a pulsed laser with a wavelength of 2.1 μ m, which has strong safety and wide applicability compared with the commonly used extracorporeal shock wave lithotripsy and pneumatic ballistic lithotripsy. In the process of lithotripsy, stones rarely run, and the return rate is very low, so the efficiency is greatly improved. It can be directly crushed through cystoscopy, ureteroscopy and percutaneous nephroscopy, without causing tissue damage. And the holmium laser fiber is flexible, so it can effectively treat ureteric and kidney stones in any site.

The study shows that the single success rate of endoscopic holmium laser lithotripsy is more than 95%, and the treatment of bladder stones can reach 100%. The procedure is non-invasive or minimally invasive, and the patient is basically painless. There is no risk of perforation, bleeding, but also the combined treatment of urinary tract tumor, ureteral polyps, stricture and so on.

The specific process is soft ureteroscopic holmium laser lithotripsy is to use a fiber optic lens with about 3mm in diameter, inserted into the ureter through the urethra and bladder to the renal pelvis and renal calyx. Holmium laser fiber is used to remove and drain the upper ureteral stones and kidney stones. The use of human natural urinary tract, without making any incision in the body, is a pure urology cavity minimally invasive technique, so it is favored by patients.
