Can a single fiber optic cable be used with a switch
The short answer is no - RJ45 connectors are designed for electrical Ethernet signals, while fiber optics transmit light pulses through glass or plastic. However, modern networks often combine both technologies. The good news: you can bridge them easily using the right hardware, such as media. If you have multiple Ethernet switches that need to be connected over long distances, fiber is obviously a preferred choice. So all PCs connected to each switch would reach the LAN/WAN from the other switch.
