Open optical networking for the AI era
Adapt and scale with flexible, disaggregated solutions that reduce complexity and support continuous innovation
Efficient bandwidth growth without operational burden
Escalating capacity, performance and security requirements are outpacing legacy optical networks. Lacking an open, flexible foundation drives up complexity, cost and modernization barriers.
We provide optical networking solutions that help operators scale capacity efficiently while ensuring consistent performance and operations across the network. Adtran supports diverse environments, from space- and power-constrained edge locations to high-capacity core nodes, using a consistent architectural approach.
With open, disaggregated designs, operators can scale networks more efficiently, adapt to changing requirements and modernize their infrastructure incrementally. Our tailored optical networking technology enables operators to maximize fiber capacity and transport data reliably, securely and with minimal latency. Combined with AI-powered automation, actionable insights and real-time in-service fiber monitoring, this approach simplifies network operations and helps prevent service outages.
