Optical modules (also known as fiber optic transceivers) are essential components in modern communication networks, enabling high-speed data transmission by converting electrical signals into optical signals and vice versa. As the demand for faster and more reliable internet connections grows, understanding these devices becomes increasingly important. Operating at the physical layer of the OSI model, optical modules are core devices in optical. When it comes to optical modules, I'm sure everyone is quite familiar with them. With the rapid development of optical communication,many scenarios in our work and life have now achieved "fiber replacing copper. " That is, metal medium communication represented by coaxial cables and network cables is. The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. While sometimes used interchangeably by newcomers, the two serve distinct but mutually reinforcing roles in high-speed communication networks.
