👉 Fibre fluid, also known as fiber optic fluid, is a specialized liquid used in the protective coatings of fiber optic cables. It serves as a lubricant, reducing friction between the cable's internal fibers and the cable's outer jacket, which helps prevent wear and tear during installation, handling, and maintenance. Additionally, the fluid contains additives that enhance the cable's durability, protect against environmental factors like moisture and chemicals, and can even aid in thermal management by dissipating heat. This combination of lubrication, protection, and thermal regulation ensures the longevity and reliability of fiber optic communication systems.
