↑ THE CLOUDLIGHT PIVOT (Nov 2023)
Before this acquisition, Lumentum only sold to Transceiver Makers. After CloudLight, Lumentum can bypass the transceiver layer and sell complete optical modules directly to Hyperscalers — capturing more margin and building a deeper customer relationship. This is the single most important strategic move in the company's recent history.
