Lumentum's 1.6T and 200G Ramp Boosts Sales Amid Hyperscaler Demand

Lumentum's transition to 1.6T transceivers and 200G-per-lane optical technology is gaining momentum as hyperscalers deploy AI clusters with increasing bandwidth requirements.

The company began shipping 1.6T transceivers in Q4 of fiscal 2026, but expects adoption to intensify from the first quarter of fiscal 2027 through calendar 2027.

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

The transition is expected to strengthen Lumentum's Systems business, with rising demand for higher-value cloud transceivers driven by tier-1 hyperscalers shifting from 800G to 1.6T.
