Abstract :
The paper reported the multiple optical carrier generation (over 1000 channels with 12.5-GHz spacing) from a single supercontinuum source. It was confirmed that these carriers have sufficient SNR to achieve Q-factors above 18.3 dB. The channel spacing is strictly determined by the microwave mode-locking frequency of the source laser and so Hz-level accuracy is possible. A transmission experiment utilizing the SC source was also presented. A 106-channel, 25-GHZ-spaced, 10-Gbit/s transmission over 640 km with Q-factors of greater than 15.6 dB was achieved. The results show that the SC-MCS can be applied to over 100-channel DWDM systems. By improving the flatness of the SC spectrum, over 1000-km transmission is achievable. It is expected that SC-MCS will be a key technology in realizing WDM networks that offer hundreds of wavelengths. A part of this work was supported by Telecommunications Advancement Organization of Japan (TAO).
