    Is the optical module part of the main device

    Operating at the physical layer of the OSI model, optical modules are core devices in optical fiber communication systems. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media.
