Across 6,900 kilometers of open ocean, a signal traveled at 800 gigabits per second — encrypted against threats that do not yet fully exist. Ciena and Colt's transatlantic trial is less a product announcement than a philosophical wager: that the infrastructure of artificial intelligence must be built not only for the demands of today, but for the vulnerabilities of tomorrow. The demonstration places Ciena at a crossroads familiar to any pioneer — having proven the possible, the harder question becomes whether the world is ready to pay for it.
