Connection methods between optical modules
Most SFP fiber optic modules use LC connectors, while SC connectors are mainly found in legacy networks and MPO/MTP connectors are used for high-density cabling rather than directly on standard SFP modules. 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. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. Operating at the physical layer of the OSI model, optical modules are core devices in optical. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications.
