What is the difference between SFP+ and DAC cable?

The SFP Exploration PART III – the DAC cable and mistakes ...

A DAC (Direct Attach Copper) cable is a fixed-length, low-cost copper cable with SFP+ connectors for very short distances (under 15m) in-rack, offering lowest latency & power, while SFP+ refers to the pluggable module/port itself that can use DACs for short runs or fiber/other media for longer distances, providing flexibility but at higher cost and power for non-DAC types. Think of DAC as a simple, cheap copper link, and SFP+ as the port/module slot that offers choice (DAC, Fiber) but costs more for the module part.

What it is:
A twinax copper cable with SFP+ transceivers permanently attached at both ends; it directly connects two SFP+ ports.
Best For:
Short-distance, in-rack connections (servers to switches, switch to switch) within ~15 meters.
Pros:
Very low cost, very low power consumption, lowest latency (no module processing).
Cons:
Limited range (typically <15m), less flexible for varying distances.
