"The industry requires significantly lower cost optical 100Gb/s connections for datacentre and access network applications and will be moving to 400G in datacentres during 2018/19. Single wavelength PAM4 100Gb/s promises a cost effective solution for 100Gb/s and enables high density 400G connections in the datacentre. This demonstration shows that this technology is coming faster than many people think," said Simon Stanley, founder and principal consultant at Earlswood Marketing Ltd, and analyst at large with Heavy Reading."
