  • Should the optical fiber and four electrical components be connected to a switch

    Should the optical fiber and four electrical components be connected to 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. General Consideration: It is generally not recommended to run fiber optic cables in the same conduit as electrical power cables.
