Transmission of 50-GHz-spaced single-carrier channels at 516Gb/s over 600km
17 March 2013
We report the first wavelength-division-multiplexed transmission of 50-GHz-spaced single-carrier channels at 400Gb/s effective data rate, i.e. achieving 8 b/s/Hz spectral efficiency. Twenty channels are sent over 600km with PDM-64QAM format operating at 43 Gbaud, received with cascaded blind equalization.
