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

Equipment

The capacitance and inductance of long lengths of cable immersed in water meant that conventional land-line transmitting and receiving equipment could not be used. A whole range of specialised equipment was developed by the scientists and engineers involved in laying and working the early cables.

This section shows some of the equipment used in the submarine cable industry over the years.

Research Material Needed

The Atlantic Cable website is non-commercial, and its mission is to make available on line as much information as possible.

You can help - if you have cable material, old or new, please contact me. Cable samples, instruments, documents, brochures, souvenir books, photographs, family stories, all are valuable to researchers and historians.

If you have any cable-related items that you could photograph, copy, scan, loan, or sell, please email me: billb@ftldesign.com
