Broadex Technologies Co., Ltd. — AI supply-chain exposure

Broadex Technologies is a Chinese producer of passive photonic components — PLC splitters, arrayed-waveguide gratings, MPO fibre connectivity and optical engines. These are the parts that split, route and combine light inside the optical modules and fibre links that carry data between servers. It sits in the networking-infrastructure layer, feeding the datacom optics that stitch AI clusters together.

AI training runs push enormous traffic between accelerators, and that traffic increasingly moves as light rather than electricity, so demand for optical interconnect scales with cluster size. Broadex's structural role is as a component supplier one level below the module makers — the passive photonics inside the transceiver. That is a less glamorous seat than the laser or the switch, but it is a real pick-and-shovel exposure to the optical build-out, which is why the model wires it into the chain despite its modest weight.
