Electrical ports and optical ports in Ethernet switches
Thread Content
What are the functions of electrical ports and optical ports in Ethernet switches?
Ethernet port: RJ45 for connecting network cables, used for distributing and forwarding data. Optical port: Connects to single-mode or multi-mode optical fibers, used for forwarding and aggregating data
This is determined based on the actual requirements at the site; generally, RJ45 twisted-pair cable is used for distances of up to 100 meters, while fiber optic media is required for distances beyond that.
One uses network cable and the other uses fiber optic cable; network cable is sufficient for distances up to 100 meters, while fiber optic transmission is required for distances beyond that.
