The optical fiber warning mat is a marker tape printed on both sides with warning information for marking the underground optical fibers, quickly warning the workers about the cables and fibers’ existence before they damage anything. These warning mats are resistant to water, UV-rays, high tension, and corrosion and stay compliant for a long duration. Our optical fiber warning mat is made from polyethylene, manufactured in yellow color. However, we do supply other colors as per the customer’s discretion. The size and warning information on the mat is subjective to our clients. The caution message printed is visible from great heights. Additionally, they don’t tear even under high pressure. They are easily identifiable, visual, and tested for optimum performance.
