Function of the built-in fiber optic port on the switch
This port is the physical interface that allows a switch's electrical circuitry to connect to a cable. Look around, and you will see ports exist in almost all transmission wired devices. Unlike fixed RJ45 copper ports, SFP ports support both fiber and copper modules, enabling far longer distances, greater flexibility, and improved scalability in enterprise. Most modern networking devices, such as Ethernet switches, servers, routers, network interface cards, and fiber media converters, generally have two or more built-in SFP ports. You may connect different switches via SFP modules and corresponding cables to the equipped port, which helps you achieve. Understand how to use these important slots for 1G, 10G, and 100G network connections.
