We propose an optical-band-multiplexing scheme to overcome the bandwidth limitation of digital-to-analog convertor, and avoid the usage of high-bandwidth radio-frequency amplifiers and mixers. We experimentally demonstrate single-photodiode detection up to 661.5-Gb/s line rate of and 527.5 Gb/s net bitrate over 250-m fiber for high-speed optical interconnects.
