Episode 93: Modems, Media Converters, and Repeaters

This episode covers modems, media converters, and repeaters, three devices that operate primarily at the physical layer. Modems modulate and demodulate signals for transmission over telephone or cable lines, media converters connect different cable types such as fiber and copper, and repeaters amplify signals to extend transmission distances. While some are legacy technologies, they remain on the exam to test understanding of physical connectivity.Examples include using a modem for broadband Internet, a media converter to bridge copper switches to a fiber backbone, or a repeater to extend signals in large buildings. Troubleshooting considerations include identifying attenuation, mismatched converter types, or outdated modem firmware. Understanding these devices prepares you to recognize exam scenarios and manage physical connectivity challenges.
