Can fibers withstand excessive temperatures? How many degrees of high temperature can a home fiber o

Optical fibers for communication are usually operated at ambient temperatures ranging from -40 +60 and are designed to be protected from large amounts of radiation. In contrast, optical fibers that can operate at lower or higher temperatures, and in harsh environments that can be exposed to high pressure or external forces and radiation rays, are called hard condition resistant fibers. Generally, in order to mechanically protect the surface of the optical fiber, an additional layer of plastic is coated.

However, as the temperature rises, the protective function of the plastic decreases, resulting in a limited use temperature. If you switch to heat-resistant plastics, such as polytetrafluoroethylene (Teflon) and other resins, you can work in a 300 degree environment. There is also in quartz glass.

The surface is coated with metals such as nickel (Ni) and aluminum (Al). These fibers are called heat-resistant fibers.

How much temperature the fiber can withstand.

Are fiber optic cables afraid of high temperatures? Different kinds of fiber have an upper limit. The operating temperature of a standard fiber optic cable is: -40 C 75 C.

If it is an industrial optical fiber, due to the different composition of each optical fiber, the high and low temperature that can be withstood are different, and the specific need to consult the manufacturer.

Optical fibers are affected by temperature.

1. The temperature characteristics of optical fiber refer to the influence of optical fiber loss under high and low temperature conditions. The loss of optical fiber increases under low temperature conditions, which is due to the different expansion coefficients of optical fiber coating layer, plastic sleeve layer and quartz, the thermal expansion coefficient of organic resin and plastic is much larger than that of quartz, low temperature shrinkage, high temperature elongation, and the optical fiber produces micro-bending under the action of this axial compression force to increase the loss. If it works at low temperatures, the fiber loss will increase as the temperature decreases, and when the temperature drops to about -55, the loss increases dramatically, making the system unable to operate normally.

2. The microbending loss of optical fiber due to temperature change is caused by thermal expansion and cold contraction. It is known that the coefficient of thermal expansion of silica (SiO2), which makes up optical fibers, is very small and barely shrinks when the temperature decreases. The expansion coefficient of the coating material and other components is larger, and when the temperature decreases, the shrinkage is more serious, so when the temperature changes, the expansion coefficient of the material is different, which will make the optical fiber produce micro-bending, especially in the low temperature area.

Fiber operating temperature range.

The upper and lower operating ambient temperature limits of fluorescent fiber optic temperature measurement systems are usually in the range of -20 +55

The measurement range of the fiber optic temperature sensor is -40 In addition, the temperature sensor with higher temperature sensing can be customized.

Generally, conventional high-temperature resistant optical fibers are -20° +300° long-term, and can reach up to 350° in the short term

The working environment temperature of the distributed optical fiber temperature measurement system is -10 50, and the temperature measurement range is -40-120; High temperature optical cable: -40—400

The FBG temperature sensor measures the temperature range -40 300

The operating temperature of the standard optical network cable is:

40ºc ~ 75ºc

Introduction: Optical fiber is similar to coaxial cable, except that there is no mesh shielding, and the center of the optical fiber is a glass core where light travels.

The main advantages of the fiber optic communication system are:

1. Transmission frequency bandwidth and large communication capacity;

2. Low line loss and long transmission distance;

3. Strong anti-interference ability and wide application range;

4. The wire diameter is thin and the weight is light;

5. Strong chemical corrosion resistance;

6. Abundant optical fiber manufacturing resources.

There is 1If the temperature of the optical fiber fusion splicer is lower than 5 degrees, please take insulation measures, otherwise the splicing loss is very large, which is greater than. If the temperature is higher than 35 degrees Celsius, cool down or rest.

2.There is a relationship to the town, the temperature is too low to affect the quality of welding, more than -20 degrees some equipment does not work, even if the welding into the operation and dismantling work attenuation is also very large, due to the low temperature of the welding temperature difference is also prone to bubbles or fried fiber.

optical fibers, i.e., optical fibers;

Its materials are: optical plastic, quartz glass, etc.;

Quartz is relatively resistant to high temperatures;

Quartz glass is glass composed of a single component of silica. This kind of glass has a hardness of up to seven on the Mohs scale, low expansion coefficient, high temperature resistance, good chemical stability and electrical insulation, and has good acid resistance to general acids in addition to hydrofluoric acid and hot phosphoric acid.

Transparent quartz glass has good ultraviolet transmission and optical properties. It is used in the manufacture of optical instruments, electrical equipment, medical equipment, and chemical instruments that are resistant to high temperatures and corrosion. High-purity quartz glass can be used to make optical fibers.
