This course provides a comprehensive overview of the various Ethernet physical layer specifications defined under IEEE 802.3. Participants will first learn about copper-based standards—such as 10BASE-T, 100BASE-TX, and 10GBASE-T—and how they leverage twisted-pair cabling to achieve reliable data transmission within typical enterprise environments. Learners will also explore legacy coaxial systems (e.g., 10BASE2 and 10BASE5) to appreciate Ethernet’s evolution over time.

A more recent extension Single-Pair Ethernet (SPE) retains full Ethernet compatibility while dramatically simplifying cabling requirements. Students will discover how SPE is uniquely positioned to address the needs of industrial and automotive networking, enabling long-distance or space-constrained deployments with reduced infrastructure.

About The Author

Pavel Burget is a researcher affiliated with the Czech Technical University in Prague, specifically with the CIIRC (Czech Institute of Informatics, Robotics, and Cybernetics), where he has been heading Testbed for Industry 4.0. His expertise spans industrial communication, including Ethernet-based systems and protocols like PROFINET. He has contributed to the field through various research projects and educational courses that delve into the dynamics of industrial communication systems, focusing on aspects like diagnostics and modeling. He has also been involved in giving Certified PROFINET Engineer courses.


Learning outcomes

  1. By the end of this course, learners will compile a comparison table that lists the speed, media type, and maximum distance for five copper Ethernet standards (10BASE-T, 100BASE-TX, 1000BASE-T, 10GBASE-T, and 100BASE-T4) and pass a formative quiz based on that table.
  2. By the end of this course, learners will evaluate three real-world networking scenarios (enterprise office, data-center backbone, and industrial control line) and select the most appropriate Ethernet physical layer for each, justifying their choices.
  3. Learners will describe the theoretical signal-integrity requirements for a 10BASE-T1L link spanning 500 m.
