A novel technique for optical label and payload generation and multiplexing using optical carrier suppression and separation

A novel technique for optical multiplexing of label and payload using optical carrier suppression and separation is proposed and experimentally demonstrated. No power penalty is observed when the payload and label, with signal extinction ratio >11 dB, are transmitted over 60-km standard single-mode fiber with full-dispersion compensation. The technique of the optical label generation offers many advantages compared with previous techniques.
