摘要

We construct a code family for spectral amplitude coding (SAC) label for optical packet switching (OPS) network. SAC labels are suitable for implementing optical multi-protocol label switching (MPLS) because they have low-complexity structure and can be fast recognized at forwarding nodes. To avoid repeated label deleting and inserting process at each node, label stacking is proposed to provide hierarchical addressing and to reduce system complexity. However, when the label set is decoded, phase-induced intensity noise (PUN) is arisen by the incoherent property of light source and degrades system performance. Thus, modified stuffed shifted prime (MSSP) code, generated by stuffed method from shift prime (SP) code, is proposed to suppress PIIN effect due to its very low cross-correlation value. In this paper, different SAC label approaches are compared - one is MSSP code and the other is Hadamard code. The improvement of packet loss probability (PLP) for packet switching is demonstrated by numerical simulations.
