Indeed, there are only three 3-regular graphs such that every perfect matching (possibly with external edges) can be extended to a Hamiltonian cycle, namely the complete graph on 4 vertices, the complete bipartite 3-regular graph on 6 vertices and the 3-cube on 8 vertices.
In the O-OFDM network layer, the core switches are interconnected with each other via optical fibers in a shape of 3-cube, while the pods are directly connected to the O-OFDM switch nodes via short-reach optical links and to the associated servers via Gigabit Ethernet (GE) ports, respectively.
This time the depiction of a 3-cube is used to determine the subject's letter choice.
