  • There are almost 450 long-distance submarine cables operating around the world today, and they are a marvel of engineering. The longest individual cables can be over 10,000 km long, and they are designed with an engineering life of over 25 years, despite being deployed in salt water at depths that would crush a human in a fraction of a second. In reality though, these systems may have a much shorter economic life, because their performance can be eclipsed by newer cable architectures and deployments.
