How to select high-temperature resistant optical fiber cables based on ambient temperature

Jun. 06, 2025

When purchasing high-temperature resistant optical fiber cables based on the ambient temperature, it is necessary to comprehensively consider the operating temperature range, material properties and actual application scenarios of the optical fiber cables. The following are some specific purchasing suggestions:

First, understand the operating temperature range of optical fiber cables

Conventional optical fiber cable

The operating temperature of standard optical fibers is usually -40

C to +75

C.

Optical fibers used in industry, due to their different compositions, may have varying ranges of high and low temperatures they can withstand. For specific details, it is necessary to consult the manufacturer.

High-temperature resistant optical fiber cable

The operating temperature range of conventional high-temperature resistant optical fiber cables is generally -20

C to +300

C (Long-term), capable of withstanding higher temperatures in the short term, such as +350

C.

Specially designed high-temperature resistant optical fiber cables, such as those with special coatings or materials, may have a wider operating temperature range.

Second, consider the impact of ambient temperature on optical fiber cables

High-temperature environment

In high-temperature environments, the insulating and sheathing materials of optical fiber cables may age more rapidly, leading to a decline in performance or even failure.

Therefore, for optical fiber cables used in high-temperature environments, materials with higher heat resistance should be selected, such as polyimide and fluoroplastics.

Low-temperature environment

In low-temperature environments, the loss of optical fibers may increase, affecting the transmission performance.

However, for most high-temperature resistant optical fiber cables, their low-temperature performance usually also meets the general application requirements. If it is necessary to work at extremely low temperatures, the manufacturer should be consulted for more detailed information.

Third, select optical fiber cables based on the actual application scenarios

High-temperature operation areas such as industrial furnaces and kilns, oil exploration, nuclear power plants, etc.

The ambient temperature in these areas is usually high, and there may be harsh conditions such as corrosive gases or dust.

In such environments, optical fiber cables with excellent high-temperature resistance and corrosion resistance should be selected, such as those with special coatings or armored structures.

Temperature measurement applications in tunnels, fire protection pipelines, oil pipelines, etc.

These applications require optical fiber cables to be able to operate stably in high-temperature environments and accurately transmit temperature signals.

In such applications, optical fiber cables with high-temperature resistant protective parts and high-temperature resistant sheaths can be selected to ensure their long-term stable operation.

Fourth, other purchasing suggestions

View product specifications and certifications:

When choosing optical fiber cables, one should carefully review the product specification sheet to understand key parameters such as the operating temperature range, material properties, and transmission performance.

At the same time, priority should be given to choosing optical fiber cables with relevant certifications, such as UL certification and CE certification, to ensure their quality and safety.

Consult manufacturers or professionals:

If you have any questions or uncertainties about the selection of optical fiber cables, you can consult the manufacturer or professionals to obtain more detailed information and advice.

Fifth, Summary

When purchasing high-temperature resistant optical fiber cables based on the ambient temperature, it is necessary to comprehensively consider the operating temperature range, material properties and actual application scenarios of the optical fiber cables. By understanding these key factors and making purchases in combination with actual needs, it can be ensured that the selected optical fiber cables can work stably in high-temperature environments and meet the requirements of communication transmission.
