Frequently asked questions

What is THE optical contract manufacturer thesis about?

**Bottleneck theme:** Photonics / CPO **Focus:** $FN — Fabrinet Fabrinet is THE optical contract manufacturer of record. The Q2 FY26 print of $1.13B (+36% YoY) — a record — reflects that essentially every major optical components vendor (Coherent, Lumentum, Cisco-Acacia, Marvell-Inphi, Innolight) routes high-mix, high-precision photonics manufacturing through Fabrinet's Thailand facilities. The franchise is built on decades of optical-process expertise that hyperscalers and component vendors don't want to replicate, plus a workforce of tens of thousands of trained operators that no Western or Chinese facility can match at the same labor-cost point. The investment case is hyperscaler-AI optical capex compounding through Fabrinet at high mix and rising margin. Volume 1.6T transceivers, CPO pilot manufacturing, and the LiDAR / sensing complement add growth vectors. The bear case is customer concentration (NVIDIA, Cisco, Coherent, Lumentum represent most revenue) and the long-tail risk that hyperscalers eventually move optical assembly in-house. Pair with $COHR, $LITE, $AAOI for diversified photonics exposure.
