In environments above 400°C, organic materials used for coatings quickly undergo thermal oxidation aging, resulting in the loss of protection for the fiber and rendering it unusable. To enable normal operation at higher temperatures, high-temperature resistant metal materials (aluminum/copper/gold) are tightly wrapped around the bare fiber. Benefits of using high-temperature resistant metals: Lower coefficient of thermal expansion (similar to the fiber's coefficient) Corrosion resistance Good fatigue resistance, water resistance, and hydrogen resistance High mechanical strength Extreme high and low-temperature adaptability Weldability Using aluminum extends the temperature range from -269°C to +400°C, while copper extends it from -269°C to +600°C. Gold can withstand temperatures from -269°C to +700°C. This type of fiber is used for ultra-longevity in harsh external environments and can also be used as components in electronic circuits. However, due to its complex manufacturing process and high cost, it is often only used in short segments where necessary. Note: The metal coating process is complex and has very low production efficiency. Stripping the metal coating cannot be done with wire strippers and requires methods such as heat-sulfuric acid fusion or nitric acid for stripping. The introduction above covers the three types of fiber metal coating materials. Quartz fiber is widely used in communication and non-communication fields due to its wide spectral range and low loss. However, it is necessary to select fibers with different coating materials based on the requirements of different applications, environments, and sectors.

Fiber doping techniques involve introducing specific materials, known as dopants, into the core of the fiber to modify its optical and conduction properties. This technique finds wide applications in fields such as fiber optic communications, fiber sensing, and fiber lasers. Here are some common fiber doping techniques: Rare-Earth Ion Doping: Rare-earth ions (such as erbium, neodymium, and terbium) are commonly used as doping agents in optical fibers. By introducing rare-earth ions into the fiber core, functionalities such as amplification, laser emission, and frequency conversion can be achieved within specific wavelength ranges. Rare-earth ion doping is crucial for improving the performance of fiber amplifiers and fiber lasers. Doping via Solution Soaking: This method involves dissolving the dopant material in an appropriate solvent and immersing the fiber into the solution, allowing the dopant to permeate the fiber core. Subsequently, heat treatment is applied to solidify the dopant within the fiber. This method enables localized doping of the fiber and allows control over the dopant concentration distribution. Vapor Phase Doping: This technique utilizes chemical vapor deposition during the fiber manufacturing process to introduce the dopant. Typically, the dopant material and the fiber's raw materials are simultaneously introduced into a reaction vessel. Through chemical reactions like thermal decomposition or desorption, the dopant reacts and adsorbs onto the fiber core, resulting in doped fiber formation. Ion Exchange Doping: In this method, ions are doped into the fiber core through ion exchange reactions. Typically, the fiber core material is silica (SiO2), while the dopant solution contains the desired ions. During the ion exchange process, the silicon ions in the fiber core are replaced by the dopant ions, thereby achieving doping. Through doping techniques, specific optical, conduction, or excitation characteristics can be imparted to fibers to meet various application requirements. The development of these techniques continually drives advancements in fiber optic communication and fiber technology.

Since the first quarter of 2022, global semiconductor market revenue has been continuously declining. In the first quarter of this year, sales were $120.5 billion, a 9% decrease compared to the fourth quarter of 2022. However, this trend seems to be getting under control. Recently, the Semiconductor Industry Association (SIA) announced that global semiconductor sales totaled124.5billioninthesecondquarterof2023,witha4.741.5 billion, a 1.7% increase compared to the previous month. In a recent annual report, SIA provided insights into the current state of the U.S. semiconductor industry in 2023. It mentioned that China is the largest single semiconductor market globally, accounting for 31% of the total market and representing 36% of the total sales of U.S. semiconductor companies. Approximately 75% of the global semiconductor manufacturing capacity is concentrated in China and East Asia. Moreover, currently, 100 out of the world's most advanced (below 10nm) semiconductor manufacturing capabilities are located in Taiwan, China (92%), and South Korea (8%).

The rod-in-tube (RIT) method is one of the conventional techniques used for optical fiber preform preparation. Interestingly, this term can also be found in other industries. In simple terms, it involves placing a glass rod inside a glass tube, heating the tube to melt it onto the rod, forming a thicker solid rod known as the optical fiber preform. Finally, one end of the preform is heated and stretched to form the optical fiber. RIT brings about various possibilities for specialty fiber development, and the tube-in-rod technique extends beyond the use in communication fibers. This technique enables more flexible fiber designs and paves the way for wider applications.

Since 2020, the global semiconductor industry has always occupied headlines, and the world has forced the world to stop working. At the same time, the impact of digitalization on life and enterprises is accelerating the development of unprecedented speeds. In turn, the semiconductor market has flourished. By 2021, sales will increase by more than 20%, and by 2021, it will reach approximately $ 600 billion. Many experts are convinced that the semiconductor industry is expected to achieve ten years of growth. By 2030, it is expected to become a trillion -dollar industry. However, it is not all good news. In fact, according to experts, the short -term prospects of semiconductor income have deteriorated. In essence, with the deterioration of the economic situation, it is inevitable that the supply is too demand. Both WSTS and Gartner's predictions show that the global semiconductor market will be dragged down in the memory semiconductor market next year. "In the latest forecast, this category is expected to fall to $ 112 billion by 2023, a 17%decrease compared to the previous year," WSTS said in its statement. In fact, Gartner believes that in the remaining time of 2022, the memory market will witness weak demand, inventory expansion, and significant reduction in prices. "Therefore, the memory market will remain stable in 2022, and it is expected that revenue in 2023 will drop by 16.2%," it said. WSTS predicts that Japan, the United States and Europe will grow in 2023, but it is expected that other regions of Asia -Pacific, including China, will decrease by 7.5%. China is the world's largest semiconductor market, accounting for more than 30%of the total. China's influence also means that the global semiconductor market may face a more serious decline in prediction than WSTS in 2023.

ccording to the Taiwanese media "Economic Daily", statistics from relevant research institutions in Taiwan, China show that the world will set off a wave of fab expansion from 2022 to 2025, or 41 new fabs will be added. Among them, major factories such as TSMC, Samsung and Intel have invested in expanding production in the United States, and the total number of new additions in the United States has reached 9 at most. According to Knometa Research data, there are currently 452 fabs in the world, with 112 in Japan, the second in Taiwan, and the third in the United States and Canada. Among them, Asia accounted for nearly 70%, 12-inch factories were 41 in Taiwan, 25 in South Korea, 26 in Japan, and 19 in the United States. Due to the growth in demand for semiconductor applications and geopolitical factors, it is estimated that 41 fabs will be built around the world from 2022 to 2025. Data analysis shows that 32 factories are located in Asia in terms of total, and the expansion of 12-inch factories is the main one. China Taiwan is estimated to add 6 factories, including 4 12-inch, 8-inch and 1 below 6-inch; Japan is estimated to increase 7 factories, including 12-inch factories and 8-inch 1; China is estimated to increase 8 In addition, there are 9 new wafer fabs in the United States, which is the largest increase, including an estimated 8 new 12-inch fabs and 1 8-inch fab. Analysts said that related capacity expansion also produces more carbon emissions, and the semiconductor industry must also improve the problems of high power consumption and high carbon emissions. Hecho specializing in design and manufacture the Fiber Optic Bundle and Fiber Optic Illuminator, which are widely used for the Semiconductor optical detection field, including Automated Optical Inspection, PCB defect detection, and so on.

In ancient times, Greek glassblowers observed that glass rods could transmit light. In 1854, Tyndall of England pointed out in a lecture at the Royal Society that light could be transmitted by reflection along curved pipes containing water, and confirmed this idea with experiments. In 1870, British physicist Tyndall observed in his experiments that when light was irradiated into a container containing water, and water was poured out from the water outlet, the light also propagated along the water flow and appeared curved, which did not seem to conform to light. The law that only travels in straight lines. In fact, the light still travels in a straight line at this time, but there is a light reflection phenomenon in the water flow, so the light travels in a broken line. Light can also "take a detour". In 1927, Baird in the United Kingdom first used the phenomenon of total reflection of light to make quartz fibers for image analysis, and obtained two patents. In 1930, someone pulled out the quartz filament, and discussed the principle of its light transmission. In 1951, the Netherlands and the United Kingdom began to develop soft fiberscopes. In 1953, the Dutchman Van Hel painted a plastic with a refractive index of 1.47 on glass fiber to form a jacket with a lower refractive index than the core of the glass fiber, and obtained a glass fiber with total reflection (insulation) of light. However, due to the non-uniformity of the plastic jacket, the loss of light energy is too great. In 1955, the phenomenon of light reflecting and traveling in a curved pipe was practically applied. Dr. Kapani, who was working at the British College in London at the time, made optical fibres from extremely fine glass. Each filament-thin optical fiber is made of two glasses with different refractive indices, one glass forming the central beamline and the other being wrapped around the central beamline to form a cladding. Due to the difference in optical properties between the two types of glass, after the light enters from one end of the optical fiber at a certain angle, it will not escape from the fiber wall, but will continue to reflect along the interface of the two layers of glass and exit from the other end. Initially, this optical fiber was only used in medicine. An endoscope composed of optical fiber bundles could observe diseases in the human stomach and intestines, and assist doctors to make accurate judgments in a timely manner. In fact, modern multi-mode optical fiber communication uses the principle of light reflection to limit the total reflection of light inside the optical fiber, and replace the electrical signal in the traditional communication method with optical signal to realize the transmission of information. Hecho is committed to the research and development and production of non-standard Fiber Optic Bundles, using high transmission efficiency optical fibers to make various optical fiber guide beams, which are widely used in in vitro diagnosis, biochemical analysis, optical detection, industrial automation, High Power Laser Fiber and other fields. Hecho has strong R&D and production capabilities, which can flexibly meet the differentiated needs of different customers.
