Cable problems can often look like application issues, but they require a different kind of troubleshooting. In this episode, we review cable specifications like length limits, signal loss, impedance, and interference resistance. You'll learn how to recognize mismatches between cable category and intended use, such as trying to run 10 Gbps over Cat 5e or exceeding fiber distance ratings.

We also touch on specialized cable applications, including shielded twisted pair (STP) in noisy environments, coaxial for certain legacy links, and fiber for long-distance high-throughput needs. Choosing the wrong cable—or installing it improperly—can introduce latency, data corruption, or complete signal failure. This episode prepares you to spot cable-related issues before they turn into costly downtime.
