摘要

A new optical label switching system with coherently detected implicit spectral amplitude code (SAC) labels is proposed in this paper.The implicit SAC labels are recognized using a frequency-swept local light source oscillator.An explicit SAC-label switching system with 40 Gbit/s intensity modulation (IM) payloads and 156 Mbit/s label and an implicit SAC-label switching system with 2.5 Gbit/s IM payloads and 156 Mbit/s labdl are both considered.Label and payload bit error rate (BER) performance is assessed and compared by simulations.The results reveal that after 80 km transmission and at the BER of 10-9,the received optical power (ROP) values of label and payload are-8.3 dBm and -23.5 dBm in implicit SAC-label switching system,respectively,while those are-18.2 dBm and-18.6 dBm in explicit SAC-label switching system,respectively.As a result,the payloads of 40 Gbit/s and 2.5 Gbit/s in explicit/implicit SAC-label switching system have little influence on the received payload quality at the BER of 10-9 after 80 km transmission.Finally,a payload of 40 Gbit/s can obtain 12.5 dB optical signal-to-noise ratio (OSNR) after 80 km transmission.
