Let 3M help manage important communication assets.

Learn all about locating and marking in the telecommunications utility industry.


Communications Cable Locating

Quickly pinpoint the location of buried facilities with the 3M™ Electronic Marker System (EMS) for Cable TV and 3M™ Electronic Marker System (EMS) for Telephone. Using 3M EMS markers during construction, installation and maintenance virtually eliminates the time consuming search for hard-to-locate facilities. Markers used for communications location are color-coded to APWA standards for visual reference and have their own frequency, helping reduce the risk of accidentally locating and excavating other buried facilities. For communications utilities, all telephone locator markers are orange and CATV markers are orange/black.

3M EMS telecom cable locator series can be used to locate:

  • Buried splices of all types
  • Buried service drops
  • Bends: changes of direction, arcs
  • Depth changes: lateral deflection
  • Fiber optic facilities with no metallic conductor
  • Encasement ends: conduit ends of horizontally directional drilled facilities
  • Manhole covers
  • Crossings: Water, road and rail
