Episode 29: Introduction to Transmission Media and Copper Cabling

This episode introduces transmission media, focusing on copper cabling as one of the most widely used network media types. It explains how copper cables transmit electrical signals and introduces the basic categories of twisted pair cabling. Key concepts such as shielding, crosstalk, and signal attenuation are defined, highlighting how they affect cable performance. This knowledge forms the foundation for understanding the physical layer of networking, which is heavily represented on the exam.

The episode also discusses where copper cabling is used in practice, such as Ethernet networks in offices, patch panels in data centers, and crossover cables for device-to-device communication. Troubleshooting examples include identifying signal loss due to long runs, diagnosing interference from nearby power lines, or recognizing improperly terminated connectors. These insights prepare you to approach both exam questions and real-world installations with confidence.
