AI data centers are accelerating demand for high-speed optical communications, extending competition in the optical transceiver market beyond chips and module manufacturing to critical upstream materials. Indium phosphide (InP), a key substrate for high-speed optical lasers and optoelectronic devices, is increasingly sought after as 800G and 1.6T transceivers gain traction. With capacity expansion requiring time and product qualification presenting technical hurdles, securing InP wafer supplies has become a strategic priority for optical communications companies.
