What are the characteristics of an optical port on a switch

Switches come in three types: those with purely Ethernet ports, those with purely optical ports, and those with a combination of both. Port types are limited to two: optical and Ethernet. Optical ports on switches typically accommodate optical modules for transmitting data via fiber. SFP (Small Form-factor Pluggable) and QSFP (Quad Small Form-factor Pluggable) are common optical module interfaces found on switches. SFP ports are small hot-pluggable module interfaces typically used for connecting fiber optics or copper cables. Switch optical modules, which convert electrical signals to optical signals and vice – versa, and optical interfaces, which serve as the physical connection points, play a pivotal role in determining the speed, distance, and reliability of data transmission. Common optical module types such as SFP. SFP ports are commonly found in switches, routers, network interface cards (NICs), and other networking equipment.
