Why is an optical module inserted into the optical port

SFP optic modules change electrical signals into optical signals. This helps data move fast and far. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. It plugs into network equipment (like switches, routers, or servers) and its primary function is to convert electrical signals from the device into light signals for transmission over fiber. On an optical network, a sender needs to convert electrical signals into optical signals before sending them to a receiver, and the receiver needs to convert received optical signals into electrical signals. SFP ports are hot-swappable, allowing you to replace or add modules without ...
