PacketLight expands quantum-safe networking with Quantum XChange

By AI, Created 1:43 PM UTC, May 18, 2026, /AGP/ – PacketLight Networks has partnered with Quantum XChange to add post-quantum cryptography to its optical networking security portfolio. The move gives customers more ways to protect data-in-motion with PQC, QKD, or a hybrid approach as quantum threats advance.

Why it matters: - The partnership gives operators a broader set of quantum-safe options for protecting optical networks against future quantum-computing attacks. - The combined offering is aimed at organizations that need long-term security for sensitive data-in-motion without ripping and replacing existing network environments. - The solution is positioned for telecommunications, financial services, government, and critical infrastructure users.

What happened: - PacketLight Networks announced a partnership with Quantum XChange on May 19, 2026, in Bethesda, Maryland. - The collaboration adds post-quantum cryptography capabilities to PacketLight’s quantum-safe security portfolio. - Customers can secure optical networks with PQC, QKD, or a hybrid combination based on security, operational, and deployment needs.

The details: - PacketLight’s existing portfolio already includes FIPS-certified Layer-1 encryption and quantum key distribution capabilities. - The new integration adds NIST-standardized PQC to that stack. - The solution uses Quantum XChange’s Phio TX, a FIPS-validated cryptographic management platform. - Phio TX supports multiple key sources, including PQC and QKD. - The platform is designed to enable crypto-agility as standards and threats change. - The companies say the combined system delivers quantum-safe encryption across DWDM and OTN networks. - The offering is built to support flexible PQC and QKD deployment options. - The partnership is also intended to help defend against “harvest now, decrypt later” threats. - The companies say the integration is designed to work with existing network environments. - PacketLight’s portfolio centers on DWDM and OTN solutions for high-capacity optical transport networks.

Between the lines: - The partnership reflects a practical shift in quantum security strategy: customers may not want to choose only one protection method as standards and threat models evolve. - By combining PQC and QKD, PacketLight and Quantum XChange are aiming at crypto-agility, which matters because migration to quantum-safe security is likely to be gradual. - The focus on existing infrastructure suggests the companies are targeting adoption friction, not just stronger encryption.

What’s next: - PacketLight says organizations can start with PQC, incorporate QKD, or run both simultaneously as standards and threats evolve. - The companies are offering expert consultations and demos for prospective customers. - For more information, visit PacketLight Networks or Quantum XChange.
