Why I invest in optical transceiver manufacturers: > I look for suppliers whose high-speed revenue is still growing from a small base. > These products already generate revenue as customers deploy them. > Industry forecasts project 800G-and-faster shipments to roughly triple between 2025 and 2030. > The 2027 pricing estimates below put 1.6T modules at roughly 2.5–2.8× the price of corresponding 800G designs. > The demand is already showing up in shipments: 400G+ module volumes rose 145% year over year in Q1 2026. Prices within each generation decline, so execution matters. Suppliers need to qualify new products and scale production while protecting margins. For me, the appeal is straightforward: revenue today, growing unit volumes, and a transition toward higher-priced modules. At the right supplier, that combination can materially change earnings. $LITE $COHR $AAOI $CRDO
