Optical modules, as core components of optical networks, are evolving toward higher speeds and improved efficiency. By 2025, 800G optical modules (OSFP/QSFP-DD) are projected to account for over 30% of the market, while 1. Optical modules, also known as optical transceivers, convert electrical signals to optical signals, and vice versa, for high-speed data transmission in networking and AI infrastructure systems. Data centres are increasingly shifting from copper wires to optical interconnect systems, because only. China's optical communication market is poised for another leap forward in 2025.
