In order to achieve optical packet switching system with high bandwidth utilization and large-capacity, based on theoretical analysis of carrier suppression principle, a scheme of optical label modulation was proposed. Simulation and experiment of the system were conducted. The results show that the center carrier suppression ratio of the carrier suppression light label is 21.3dB. Under label modulation rates of 622Mbit/s and 1.25Gbit/s, bit error rate (BER) of the system is lower than 10-10 when transmission distance is over 40km. In the standard of BER 10-10, power penalty of two label modulation rates is 1.7dB and 1.9dB when transmission distance is 40km. Carrier suppression light label in optical packet switching system has high extinction ratio and low power penalty, therefore it is suitable for long distance transmission.
