Coherent (COHR) The Six Five Summit: AI Unleashed 2026 summary

Industry trends and challenges

• Optical networking is now central to global communications, driven by the need for higher speeds and longer distances in data transfer.

• Data centers face power constraints, pushing AI workloads to span multiple sites and increasing demand for high-bandwidth interconnects, known as scale across networks.

• Energy efficiency and bandwidth remain top priorities for network designers, especially in AI data center contexts.

• Optical networks are becoming more disaggregated, with modular components replacing monolithic systems.

Key technologies and innovations

• Two main functional blocks for scale across: data center interconnect transceivers (DCI) and optical transport equipment, which amplify, condition, and monitor signals.

• The Multi-Rail platform enables a fourfold increase in network capacity within the same physical space, with sublinear scaling of power requirements.

• Indium phosphide is a critical platform for AI connectivity, supporting various optical functions.

Competitive differentiation and manufacturing

• Deep vertical integration allows for innovation from materials to systems, enabling tailored solutions and rapid scaling.

• Manufacturing capacity is being doubled repeatedly to meet unprecedented AI-driven demand, with over 50 global sites and significant U.S. presence.

• In-house production of nearly all components provides supply chain resilience and agility.
