Abstract :
Coherent optical time-domain sampling is proposed to relax the requirement for photodetector bandwidth as well as the speed of analog-to-digital converter (ADC) and digital signal processing. Transmission of 10-Gb/s binary phase-shift keying signals over 220-km standard single-mode fiber was demonstrated using 10-Gsa/s ADCs.
