Infinera announced two milestones for advanced coherent technologies:
pushing optical transmission to 100 gigabaud (GBaud) - this compares with typically deployed baud rates of 32 GBaud with the quadrature phase shift keying modulation carrying 4 bits per baud. Industry opto-electronics are moving to 66 GBaud development demonstrations. Infinera has surpassed this by being the first to showcase 100 GBaud using 32QAM to achieve a single-wavelength...
