On June 10, Ciena Corporation (NYSE:CIEN) and Colt Technology Services reported they completed a transatlantic trial transmitting safe quantum data at 800GbE across 6,900km between New York and London. It marked one of the fastest demonstrations of its kind. The companies stated that the test used Ciena’s WaveLogic 6 Extreme encryption to protect live data and maintain ultra-high speeds.

The firms warned of rising “harvest now, decrypt later” threats. The attackers could store intercepted data for future quantum decryption, potentially viable by 2030. The corporations cite research that 69% of organizations see quantum risk and 46% fear large-scale data exposure.

Colt COO Buddy Bayer said the trial “proves that quantum-safe protection can be delivered at real-world scale,” and the infrastructure supports secure growth for hyperscalers and enterprises.

Ciena Corporation (NYSE:CIEN) SVP Dino DiPerna said the test shows post-quantum cryptography can secure high-speed services “over real-world long-haul and submarine networks.” It also addressed surging demand and evolving security risks.

4. Corning Incorporated (NYSE:GLW)  

On June 12, Corning Incorporated (NYSE:GLW) CEO Wendell Weeks, speaking to The Wall Street Journal, said the company has risk-sharing provisions in multibillion-dollar fiber deals with Nvidia, Meta, and Amazon. It requires customers to bear demand uncertainty while the firm focuses on R&D and production. He argued, “there’s certain risks that really belong with their shareholders,” and that customers must take responsibility for the risk of overestimating needs.

The WSJ reported Corning’s stock has roughly doubled since January, and the company plans to grow sales 50% by 2028, riding AI-powered data center demand. CEO Weeks recalled the dotcom crash, saying those lessons shape the current strategy and help avoid overcommitment despite strong orders.

Raymond James’ Frank Louthan told WSJ such terms are unusual. He noted large customers typically dictate vendor economics. Weeks countered that the firm’s decades of R&D and specialized fiber technology provide leverage to demand upfront capital.

Weeks added demand remains solid, but insisted Corning Incorporated (NYSE:GLW)  will not “bet the family farm” on AI spending cycles.
