摘　　要：报道了光分组交换网络中基于多组光正交码组合光标签的识别与接收实验,光标签采用了码长为19,码重为3的2组光正交码组合光标签方案.给出了基于多组光正交码光标签的光分组交换网络(MOOC-OPS)基本原理,通过分析指出在MOOC-OPS网络中处理多组在时域上非连续、随机、突发光标签是现实MOOC-OPS关键技术之一.设计出了基于展宽网络和放大器级联方式接收多组低功率窄脉冲(MOOC-OPS网络的光标签)的实验方案,完成了实验电路板制作与实验验证.实验结果表明成功地实现了MOOC-OPS网络中周期为2ns基于多组光正交码光标签脉冲的识别接收,验证了该方案的可行性.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.
