Linking fibre optics with copper Ethernet is the job of a media converter: it translates the signal between the two, stretching a network across distances regular cable cannot cover. The category includes converters for single-mode and multi-mode fibre, speeds from 100 Mbit/s to gigabit and beyond, and models with an SFP slot for interchangeable modules. Match the converter to your fibre and connector type, required speed and transmission distance, then check the power supply and whether rack mounting is needed.
