Year Route Manufacturer Company or Operator Cable Ships Notes
1845 Laid between HMS Blake and HMS Pique in Portsmouth Harbour S.W. Silver & Co S.W. Silver & Co HMS Blake - HMS Pique Charles West of S.W. Silver & Company manufactured one mile of cable insulated with rubber and carried out tests on it in Portsmouth Harbour. He subsequently obtained permission from HM Government to lay a cable across the English Channel, but was unable to raise the necessary capital so the idea was dropped.
1850 Dover, England - Calais, France Gutta Percha Co 25 nm Submarine Telegraph Co Goliath - HMS Widgeon System 25 nm. CABLE: 1 copper wire No 16 BWG covered with gutta percha to No 2 BWG. 8 or 16lb lead weights were attached to the cable as it was laid to help it sink,. Cable was cut by French fisherman after three days
1851 Dover, England - Calais, France (St Margarets Bay - Sangatte No 1) Gutta Percha Co supplied the core. - R.S. Newall & Co - Wilkins & Wetherly Submarine Telegraph Co HMS Blazer (1) - HMS Fearless - Red Rover (1) System 25½ nm. CABLE: 4 copper wires No 16 BWG each covered with gutta percha to No 2 BWG, then formed into a cable. The spaces were packed with tarred yarn and a further layer of gutta percha was added. Tarred hemp was wrapped around the core then it was armoured with 10 No 1 BWG iron wires. Cable ran out before reaching France. A temporary repair was made. Red Rover laid replacement a month later. Taken over by the GPO in 1890. Wilkins & Wetherley were awarded the contract to add the armouring, but in doing so they infringed Newall's patent and so the bulk of the work was carried out by Newall's
