Feb X 2017 update notes for Visio by DPTPB stencil collection, part 3
40GbE to 4x10GbE breakout cable shapes
With most 40GbE switches there is possibility to split a single 40GbE port to four 10GbE ports by using breakout cable with one QSFP+ connector at one end of the cable and four 10GbE SFP+ connectors at the other end of the cable.
Available both for fiber and direct-attached connectivity. Fiber connection has separate transceivers + a breakout cable with 1x 40G MPO connector / 4x10G LC connectors. DAC cable is a single piece of hardware.
