With the acceleration of AIGC, ChatGPT and other technologies, the global Internet demand for high-speed data transmission is increasing. The development of optical communication modules toward high-speed transfer has become an inevitable trend.  InP materials are mainly used in the manufacture of high-speed positive-intrinsic-negative (PIN) or high-speed avalanche photodiode (APD) in optical modules. The new generation of InP optical communication products supports high-speed optical communication with its higher data transmission rates.
