Scalability limitations of 40G OTU3 / 40G DWDM in optical transport networks

The 40G OTU3 / 40G DWDM technology failed to scale and become a dominant solution in optical transport networks, unlike 100G. Several factors may have contributed to this, including modulation limitations, poor spectral efficiency, OSNR requirements, and cost per bit. The root cause of this limitation is not well understood.
