👉 Modem fluid, also known as optical fiber cable fluid or cleating fluid, is a specialized lubricant and sealant used in the installation of fiber optic cables. It serves multiple purposes: it reduces friction between the cable and its protective jacket, ensuring smooth insertion and handling during installation; it provides a barrier against moisture, dust, and other contaminants that could damage the delicate fiber optic strands; and it helps to maintain the integrity of the cable by preventing the jacket from becoming brittle or degrading over time. This fluid is crucial for maintaining the long-term performance and reliability of fiber optic networks, enabling efficient data transmission with minimal signal loss.
