The experiment of multiple optical orthogonal codes （MOOC） sequences-based optical labels receiving is reported for the first time. In this work, 2 groups of MOOC with code length 19 and code weight 3 are used to identify optical labels. This paper firstly presents the scheme and principle of optical packets switching networks based on MOOC sequences-based optical labels. Since optical labels contain the optical packet switching and routing information, optical label processing is crucial to achieve successfully packets switching. Therefore, the importance of MOOC-based optical labels processing with multiple inconsecutive, random and burst characteristics in optical packets switching network is pointed out. Considering the MOOC-based optical labels, we design a circuit consisting of widened net and multi-level concatenated amplifiers to receive multiple single-optical-label pulse with a period of 2 ns and low power. The experimental resul ts show that the designed scheme is feasible.
