The main component of optical fiber is high-purity silicon dioxide.
1, the main component of optical fiber is high-purity silicon dioxide, its preparation requires a number of processes, including the preparation of rods, pre-stretching and stretch molding.
2, optical fiber has the advantages of fast transmission speed, high communication quality, low signal loss, large data transmission, compact size, light weight, etc., and is widely used in communication, medical, scientific research and other fields.
I. Definition and Usage of Optical Fiber
Optical fiber, also known as fiber optics, is a material that transmits optical signals over long distances. It is a linear structure consisting of a core in the center and a cladding that surrounds the core, and is widely used in the fields of communications, medical care, and scientific research because of its small size, light weight, and low signal loss.
Two, the main components of the optical fiber
1, the main component of the optical fiber is high-purity silicon dioxide, its content can reach more than 99.99%. Silicon dioxide is an inorganic compound, usually a white powder with the molecular formula SiO2, a very stable compound with excellent resistance to heat, acids and alkalis.
2. In addition, there are a small number of dopants, such as erbium and erbium, etc. By selecting the dopant and adjusting the amount of doping, the optical properties of the optical fiber can be changed to meet the needs of different fields.
Three, optical fiber manufacturing process
1, the preparation of rods: first of all, you need to mix the high-purity silica powder and dopant, prepared into small rods.
2, pre-stretching: the prepared small rods into a special sintering furnace for heating, will be pre-stretched into a smaller diameter rod.
3, stretch forming: Next, the pre-stretched rod needs to be stretched continuously until it is only a few microns in diameter, forming a thin, soft optical fiber.
Four, the advantages and disadvantages of optical fiber
1, the advantages: optical fiber transmission speed, high quality of communication, low signal loss, data transmission, small size, light weight and other advantages, is the traditional copper wire and coaxial cable and other traditional communications media can not be compared.
2, disadvantages: optical fiber manufacturing process is complex, high manufacturing costs; in addition, because it is a glass material, vulnerable to physical impact or bending and damage.
Fifth, the application of optical fiber
1, the field of communication: optical fiber in the field of communication is widely used, can be used for telephone, mobile communications, the Internet, radio and television broadcasting, and other forms of communication.
2, medical field: optical fiber can be used in endoscopy, minimally invasive surgery, heart valve surgery and other medical equipment, through its high precision and non-invasive advantages, effectively enhance the success rate of medical surgery.
3, the field of scientific research: optical fiber can also be used in the field of scientific research, for example, suitable for laser experiments, astronomical observation, meteorological prediction and so on.
