Unlike. With the rapid development of AI computing power, cloud computing, and data center networks, optical communication systems are continuously evolving toward higher bandwidth. As data transmission rates increase from 400G to 800G and up to 1. 6T, power density is also rising significantly. While polymers and certain metals have their place, advanced ceramics offer a unique combination of properties essential. High-performance ceramic substrates for optical communication modules. Excellent thermal conductivity, signal integrity, and precision for photonics and high-speed data transmission. Light communication modules like ROSA (Receiver Optical Subassembly) and TOSA (Transmitter Optical Subassembly) rely on ceramic enclosures to maintain signal integrity in high-frequency optical systems, enabling.
