Design and experiment of optical orthogonal code-based optical labels receiving in optical packets switching

Abstract

In an optical packet switching (OPS) system, the label processing is crucial for OPS, since the optical label carries the switching and routing information of optical packets. This paper introduces the scheme and the principle of the Optical Orthogonal Code (OOC)-based optical labels for OPS networks, and points out the importance of optical label processing with inconsecutive, random and bursting characters. Considering these of optical labels, we designed a circuit consisted with widening net and cascading multi-level amplifiers to receive single tiny narrow pulse of optical labels, the experiments results indicate the designed scheme is effective.
