Features of outdoor armored optical fiber cables
Let me introduce the main features of outdoor armored optical fiber cables in detail.
Mechanical properties:
- The armor layer is made of metal material, which can significantly improve the cable’s tensile, compressive and bending resistance.
- These mechanical properties can effectively meet various stress and load requirements in harsh outdoor environments.
- For example, the cable can withstand greater tension, pressure and bending, making it safer and more reliable during laying and use.
Environmental resistance:
- The armor layer provides excellent water resistance, moisture resistance and corrosion resistance, protecting the internal optical fiber from environmental factors.
- This environmental adaptability ensures that outdoor optical fiber cables can work stably and for a long time under harsh climatic conditions.
- It improves the reliability and service life of the cable and reduces maintenance costs.
Anti-electromagnetic interference:
- The armor layer is made of metal material, which can effectively shield external electromagnetic radiation and interference signals.
- This electromagnetic shielding function ensures the integrity and transmission quality of the optical fiber signal and avoids distortion or loss caused by interference.
- Especially near some high-voltage lines and power equipment, this anti-interference performance is even more important.
Safety:
- The armor layer has good anti-cutting and anti-crushing properties, which can effectively protect the internal optical fiber from accidental damage.
- This safety feature reduces the risk of accidental damage to the optical fiber and improves the safety of the entire optical fiber system.
- In some special environments, such as traffic routes, construction sites, etc., this safety performance is even more important.
In short, outdoor armored optical fiber cable is very suitable for use in harsh outdoor environments with its excellent mechanical properties, environmental adaptability, anti-interference and safety, providing a reliable transmission basis for optical communication systems.
