Asian countries, despite being located in the world’s largest landmass, are interconnected through submarine optical fiber cable networks. Ciena Corp. has found that a terrestrial cable gets cut in every 30 minutes and a submarine cable is damaged in every three days somewhere in the world. And the IT downtime costs more than $25 billion a year to the customers. Ability to rush the maintenance crew ensures the terrestrial cables’ lower downtime than its underwater counterpart.
