A novel scheme of generating multi-frequency spectral amplitude code labels by employing a single laser and a Fabry-Perot tunable filter

We propose a new method of generating multi-frequency spectral amplitude code (SAC) labels with a single laser and a Fabry-Perot tunable filter. Our proposal offers a substantial simplification in terms of required optical sources to build a SAC label transmitter. SAC label up to 16 frequencies could be generated by a single wavelength laser, and the label bit rate is accelerated to 1.25 Gb/s. Received label quality is estimated by bit error rate (BER) performance.
