Super channel generated by an optical frequency comb was employed in optical label switching system. Firstly, the optical frequency comb which can generate 60 available spectral lines was realzied, thus it provides good optical source for both optical label and super channels. Then, an optical label switching system with 1.25Gbit/s optical label and 6Tbit/s super channels was built up by applying orthogonal frequency division multiplexing (OFDM). Simulation results indicate that, at a bit error rate (BER) of 10-9, the received optical power of each channel and optical label is about -5.3 and -18.12dBm, respectively.
