History of the Atlantic Cable & Undersea Communications
from the first submarine cable of 1850 to the worldwide fiber optic network

Cable Timeline: 1901-1950

Click on the Route links to see cable samples, the Company or Operator links for full descriptions, the ship name links to see descriptions or images.
Atlantic cables and their connecting systems are highlighted in green, and cable repairs have a blue background.
John Seymour links in the Timeline between 1875 and 1897 are to the descriptions of those voyages in Dougal Watson's extensive section on his ancestor's life at sea.
Please note that Timeline entries within each year are not necessarily in chronological order, as the exact date of laying is often not known.

Entries between 1901 and 1912 on this page with detailed manufacturing records in the notes column, as well as those listing repairs at the end of each year, have information from the Telcon Record Book of Submarine Cables Manufactured and Laid by the TC&M Company. Volume 1: 1850-1912. High resolution scans of this book were made by its present curator, Alcatel-Lucent of Greenwich, successor to the Telegraph Construction & Maintenance Company, and were provided to the Atlantic Cable website by Allan Green. Thanks as always to Bill Glover for his meticulous transcription of these records.
