| Tools for this tag |
The tag telecom=cable_landing_station (CLS) is used to map a specialized telecommunications location where submarine telecoms cables terminate when they return to shore. A CLS's core functions are:
- House the Power Feed Equipment (PFE) connects to the cable's copper electrical conductor and delivers high voltage DC power to optical in-line amplifiers placed on the seafloor as the cable is being laid.
- House the Submarine Line Terminal Equipment (SLTE) connects to the cable's the optical fiber and specialty long reach coherent DWDM, muxes and add / drop equipment which modulates, demodulates and monitors the wavelengths of light carrying network traffic across the fiber.
This tag is only intended for locations with submarine network cable termination as its main purpose.
How to map
Cable landing stations are often dedicated stand-alone buildings very near the beach where a cable lands, thus are usually mapped by drawing an outline around the building=service area , then one would add telecom=cable_landing_station to the building.
If a cable landing station is colocated within a telecom=data_center, (or some other shared building=*) use a node tagged with telecom=cable_landing_station to mark the cable landing station's approximate position within the larger structure; e.g., a room or suite in the building=*.
Tags used in combination
Use the following tagging to describe a cable landing station:
| Key | Value | Comment | Recommendation |
|---|---|---|---|
telecom=* |
cable_landing_station |
Apply tag to a dedicated stand-alone building area or as a node in a shared building |
Mandatory |
| In combination with... | |||
building=*utility=* |
servicetelecom |
If a dedicated stand-alone building, use these tags on the building area in addition to telecom=cable_landing_station |
Recommended |
operator=*name=*addr:=* |
<text> | The station's name (e.g., Ocean Beach CLS); operator (e.g., Telecoms Company, Inc.); and address | Optional |
landuse=*utility=* |
industrialtelecom |
If the building sits on its own land area , consider tagging the site boundary with these tags |
Recommended |
Disused stations
- Add the tag
disused=yesif the station is decommissioned but could easily be used again. disused:telecom=cable_landing_stationif the station has been abandoned and can not be repaired.historic:telecom=cable_landing_stationif the station has been demolished.
