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.
