T&S Communications Co., Ltd. — AI supply-chain exposure

T&S Communications is a Shenzhen-listed maker of fiber-optic connectors and MPO/MT cable assemblies — the structured connectivity that physically links equipment across a data-center fabric. It supplies the plugs, trunks and pre-terminated assemblies that get fiber from one rack to another, including to international optical customers, sitting one step up from the raw fiber in the interconnect layer.

The hook is that AI clusters have turned cabling from an afterthought into a volume business. High-density GPU fabrics need enormous counts of high-fidelity fiber connections, and MPO/MT assemblies are the standard way to deliver them at scale. Connector precision and clean assembly matter for signal integrity, which favors established suppliers, but the product is more contested than the fiber or the optics themselves. The model reads T&S as a modest supplier exposure to optical interconnect.
