40G QSFP+ DAC/AOC Cables

There are several ways you can realize a 40-gigabit Ethernet connection. One of the most common and efficient ways is QSFP+ or quad small form-factor pluggable. The quad form-factor ports will accept both QSFP+ transceivers and modules of the same size on DAC and AOC.

Transmission via DAC or direct attach copper cables can work in two ways. Firstly, QSFP+ to QSFP+ DAC cable or QSFP+ to SFP+ x4 DAC breakout cables. The third option is to use AOC or active optical cables with fixed modules that are plugged directly into QSFP+ ports.
