ADTRAN (ADTN): Quantum-Safe Optical Transport Adds a Security Layer to AI Data Center Connectivity Habib Ur Rehman Mon, June 15, 2026 at 2:28 AM GMT+7 2 min read ADTN ADTRAN Holdings, Inc. (NASDAQ:ADTN) is one of the best AI networking stocks to buy according to analysts. The company gave investors a recent optical networking angle on May 27, when eu Networks launched a new quantum-safe private connectivity service powered by Adtran’s encrypted optical transport technology.
The new Quantum Shield service was developed to protect sensitive data moving between European data centers, using Adtran’s optical transport technology to support secure, scalable data center connectivity across euNetworks’ pan-European network. Adtran said the infrastructure is built on its FSP 3000 optical transport platform, incorporates S-Flex technology for high-capacity encrypted data center interconnect services, and uses post-quantum cryptography aligned with NIST standards.
The relevance to AI networking is that AI workloads increase the importance of secure, high-capacity data-center connectivity. Adtran’s optical layer also includes real-time fiber monitoring through its ALM solution, which the company said can detect and locate fiber-tapping events while supporting low latency, high throughput, and enhanced security.
