Episode 25 — High-Speed Interfaces — Gigabit, 10 GigE, SFP, and QSFP
This episode examines high-speed networking interfaces and their roles in modern server connectivity. We compare Gigabit Ethernet to 10 Gigabit Ethernet in terms of throughput, cabling requirements, and typical use cases. The discussion also explores modular transceiver standards such as SFP and QSFP, explaining their form factors, data rates, and compatibility considerations.
We provide examples of how these interfaces appear in both exam scenarios and operational planning, from upgrading a server’s NIC to supporting backbone links in a data center. The episode also covers troubleshooting practices, such as identifying a faulty transceiver or verifying link negotiation speeds. Mastery of high-speed interface concepts ensures candidates can confidently choose and maintain the right connectivity options for performance and scalability needs.
