Very first Transatlantic cable fails after 732 messages

The first transatlantic telegraph cable, completed in August 1858, failed after transmitting only 732 messages. Despite initial successes, the cable’s performance quickly deteriorated due to technical issues, including the insulation breakdown and excessive voltage applied during transmission. This premature failure underscored the challenges of undersea telegraphy and highlighted the need for more robust materials and better engineering solutions. It wasn’t until 1866, after several more attempts and advancements in cable technology, that a reliable and durable transatlantic cable was successfully laid, paving the way for continuous and reliable communication between Europe and North America.
