Lumentum Holdings Inc. is benefiting from the accelerating transition towards 1.6T transceivers and 200G-per-lane optical technology as hyperscalers deploy increasingly bandwidth-intensive AI clusters.

The company began shipping 1.6T transceivers in Q4 of fiscal 2026, while the bulk of its cloud transceiver shipments remained at 800G.

Lumentum believes improved design engineering has helped it reach the market ahead of larger competitors like Cisco Systems and NVIDIA in next-generation AI connectivity.
