Cable Data

TeleGeography's interactive submarine cable map shows the majority of active and planned international submarine cable systems and their landing stations. Selecting a cable route on the map provides access to data about the cable, including the cable's name, ready-for-service (RFS) date, length, owners, website, and landing points. Selecting a landing point provides a list of all submarine cables landing at that station.

NB: Anyone planning work that could affect any submarine cable should contact the relevant charting authorities, telecommunication companies and appropriate government agencies prior to the start of operations.

Note: The ICPC Secretariat may be able to assist you in identifying submarine cables in your area of operations. Please e-mail the following information to


The ICPC is developing a list of submarine power cables, including landing points, operating capacity and Maintenance Authorities. The list can be viewed by clicking here.


Since the beginning of the 1990's the need to obtain various forms of scientific data (e.g. oceanographic, seismic) has meant that a number of redundant telecommunications cables have been put back into service under new owners who are not part of the telecommunications industry. These cables have actually been notified by their original owners as out of service to hydrographic offices and may have been removed from navigation charts, however on cable charts they are usually designated as out of service. It is therefore essential to check the status of these cables prior to the start of any operations in the vicinity. The list can be viewed by clicking here.
