RJ11 vs. RJ12 vs. RJ45 Patch Panels: What's the Difference?
RJ11 is 6P4C, RJ12 is 6P6C, RJ45 is 8P8C. Compare voice vs Ethernet patch panels — and what to check before an RJ11 plug meets an RJ45 jack in the...

Understanding SFP, SFP+, QSFP and Beyond: Choosing the Right Transceiver for Your Application
One cage, many speeds: SFP, SFP+, SFP28, QSFP+, QSFP28, and QSFP-DD look alike but do different jobs. Here is how to match each to rate, distance, and fiber.
