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

Our interactive application guide shows you where 3M Locating & Marking products are applied in commercial and residential spaces and why they’re better than conventional approaches.

Data Centers
  • Data centers host critical infrastructure for high value transactions globally.
  • Markers and Path Markers are used to locate high value assets in order to help avoid possible damage.
Cell Towers
  • Cell towers are used to provide cell service but requires high
  • bandwidth fiber connections.
  • Use path marking to help eliminate high voltage lightning path like tape for trenches or in-conduit rope.
  • Use point markers to mark the first handhole.
Maintenance and Repair
  • Higher risk point for future failures, where to look first when
  • there’s an issue
  • Easily able to identify and map
  • Ease of identification using a marker and precise positive location
EMS ID Markers for Buried Cable
  • Provides information to installers and maintenance including: cable
  • type, size and material
  • Allows pinpoint locating of fiber and copper
Handhole
  • Markers installed inside handholes are used to locate splices and
  • terminations along cable runs.
  • Environmental effects may cover handholes overtime and become difficult to locate. Markers can be found under vegetation, dirt, snow, etc.
Ball and Near Surface Markers
Path Marking
  • 3M EMS Caution Tape and Rope
  • For use in open trench and HDD (Horizontal Directional Drilling) applications
  • A maintenance free solution for marking and locating the path of underground plastic pipes and casing.
