Overview of Our Buried Fiber Optic Cable Flags
The Buried Fiber Optic Cable Flag serves as a visual warning to indicate the presence of underground fiber lines, helping prevent accidental damage from digging or construction work. These flags are widely used by fiber internet service providers, municipal utilities, construction firms, and OSP (Outside Plant) engineers.
Our standard configuration includes a 4″ x 5″ high-visibility poly flag mounted on a 30″ galvanized steel wire staff, which is the most commonly used size among fiber providers. However, we also offer customizable flag sizes, wire lengths, and printed messages tailored to your project or branding requirements.
