There are two major advantages of 25G technology. First, by offering a single-lane 25Gbps variant, 25G allows for optimization of the bandwidth available from switch-fabric design, which is typically viewed from a per-pin and therefore per-lane standpoint. And the other major advantage is it takes existing module form factors and optical plants factors, such as SFP28 and QSFP28, and allows for a breakout connection that is configurable as either 25G per lane or the full 100G without changing the port on the front of switches and the wholes physical infrastructure.
