Fiber cable markers for underground cable are essential to identify buried fiber and to avoid accidental damage.

Marker Ball

Marker Balls are ideal for marking fiber cable in high-voltage environments. When excited by any standard marker locator, the marker ball produces a 5-foot spherical RF field, identifying the presence of fiber cable below. Because the RF field is spherical, the marker ball does not require any particular orientation when buried. It fits easily into a standard 4-inch trench with no extra digging.

Marker Tape

3″ x 1000′ roll Marking Tape, both non-Detectable and detectable, is available. The orange tape is marked “CAUTION FIBER OPTIC CABLE BURIED BELOW”. Underground marking tape is buried 12-24 inches below grade level, and warns excavators of a buried fiber optic cable in time to prevent damage and service interruptions.

Marker Post

Fiber Marker Posts provide a convenient and effective way to protect and identify underground fiber optic cable facilities. Standard 6 foot long with an orange dome cap and are available with custom printing.
