Cloud connectivity for the AI era
Interconnect solutions designed to handle AI-driven traffic with performance, efficiency and security
Cloud-centric networks made simple, secure and efficient
Cloud and AI-driven traffic growth demands interconnects that scale quickly and seamlessly, meet tight power, space and performance requirements, and safeguard data against attacks.
Adtran delivers cloud interconnect solutions that help operators scale capacity efficiently across a wide range of deployment models. Built on decades of experience and tailored innovation, our solutions emphasize openness and simplicity, enabling faster deployments and easier scaling as traffic grows. Real-time visibility across optical and fiber infrastructure helps teams identify and solve issues earlier and operate proactively. For environments with higher security requirements, embedded post quantum cryptography safeguards data in motion against evolving cyber threats. The result is scalable, secure and reliable interconnects that support expanding cloud and AI workloads without adding unnecessary complexity, reducing power consumption, footprint and cost.

MicroMux™ Quattro
FSP 3000 IP OLS
Innovative QSFP-DD pluggable transceiver that transforms a single 400GbE port into four 100GbE ports or two 200GbE ports without increasing footprint, enabling efficient cloud hand-offs.
Tailored designs
Building future-proof cloud interconnects
Data centers, edge sites and core networks are seamlessly connected over an open, disaggregated optical transport layer. Services are transported via DWDM optics in IP devices or thin transponders over a scalable open line system that provides fiber and optical performance visibility, while open, standardized APIs enable end-to-end orchestration.

Streamlined IP-optical convergence
Our technology simplifies the deployment and scaling of cloud interconnects, reducing power, space, and equipment needs. Turnkey open optical networking solutions enable operators to transport Terascale capacity over short to long distances on a single fiber pair with the highest reliability and data security. They also gain full visibility into optical and fiber infrastructure, minimizing downtime and enabling proactive operations. This approach empowers operators to deploy open, secure, long-lived interconnects that are easier to operate and ready for next-generation cloud and AI workloads.
