Introduction: Hundreds of submarine communications cables have been laid since the early attempts of the 1840s and the first commercially successful cable, the England to France link of 1851.

Bill Glover's ongoing project presents a comprehensive time line of all major cables and many of the minor ones, with links to cable sample images, company descriptions, and cableship histories.

This page also includes other related articles on cables.

Special thanks to Gill Cookson, Allan Green, Steve Roberts, and the other contributors listed below for their help with these pages.

If you can add cables we have overlooked, or update any of the missing information (shown as ? in the listings) on cable manufacturers, cableships used, or other details, please email me.
