Does the optical module contain optical fiber
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 world through a fiber optic cable. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media. 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.
