Key takeaways What it is: A high-density switch built for 25GE access + 100GE/40GE aggregation, commonly used as campus core / building distribution or a data center leaf (ToR). Why it matters in 2026 designs: The port template (48×1/10/25G SFP28 + 8×40/100G QSFP28) supports phased...

Intro Ethernet switch port types define the performance, scalability, and architecture of modern networks. RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density ...
