Improved Power Budget of 112 Gb/s/$\lambda$ Intra-Datacentre Links Using a Split-Carrier Transmitter Architecture [PDF]

IEEE Photonics Journal, 2019
A split-carrier transmitter is proposed to improve loss budget for short distance 100 G-per-wavelength intra-datacentre links. By applying a low-complexity hardware modification to the transmitter, the proposed architecture reduces transmitter loss without sacrificing modulation quality.
