Episode 40: Ethernet Standards over Fiber and Multiplexing

This episode introduces Ethernet standards over fiber optic cabling, which enable high-speed communication across longer distances than copper. Standards such as 1000BASE-LX, 10GBASE-SR, and 40GBASE-LR are explained in terms of wavelength, range, and use case. The episode also covers multiplexing techniques, including Wavelength Division Multiplexing (WDM), which allow multiple signals to be transmitted over the same fiber, greatly increasing efficiency.You will also learn how to apply this knowledge in real-world scenarios, such as using short-range multimode standards for data centers or long-range single-mode standards for campus networks. Troubleshooting examples include identifying when transceiver mismatches prevent proper operation or when excessive splice losses reduce performance. Mastering fiber-based Ethernet standards ensures you can distinguish them from copper equivalents on the exam and deploy them effectively in professional settings.
