Not all external peripheral devices need a cable. There are a growing number of devices that use wifi (wireless and no cable required). You can use a wifi keyboard and a wifi mouse. There are wifi printers, and so on.

Fiber optic cable is not subject to EMI and RFI interference because it transmits data using light signals through glass or plastic fiber strands, rather than electrical signals through copper conductors. This makes fiber optic cable ideal for environments where high levels of interference are present, such as near power lines or in industrial settings.
