I've been researching a lot and still haven't found a clear solution. I'm trying to link two 10G switches together. I see options like passive SFP+ cables with active SFP+ adapters (SFP+ to RJ45). The main concern is keeping the wiring neat, short, and within a reasonable length—usually under three feet, often around two feet or less. A smaller bend radius would be helpful, especially since the switches aren't currently placed next to each other. I've been worried about heat buildup from transceivers and active cables potentially affecting the switches, but I also read they might improve speed. So, which approach is actually better? Let me know if I'm on the right track. Edited January 5, 2025 by OhioYJ

I believe passive SFP+ DACs suit shorter runs best. 10GBASE-T SFPs seem unnecessarily costly, with no options under $50 per port discovered. It doesn’t need much analysis—any fix should be fine.

They emit a lot of heat and are less common, which makes them newer—around 2018 they began to appear more often. A 10Gb fiber SFP typically uses about 0.1 to 0.2 watts (excluding long-range ZR optics). A 10Gb copper SFP averages around 2.5 watts.
