Abstract

We experimentally demonstrate high-speed optical pseudorandom bit sequence (PRBS) multiplexing with coarse and fine bit-rate tuning capability and a switchable order using optical delays. Data multiplexing of 80Gbit/s and 160Gbit/s is shown, each with a tunable rate using a conversion/dispersion-based continuously tunable optical delay and tunable PRBS order with large switchable fiber delays. A 7% bit-rate tunability, i.e., 8085.6Gbit/s and 160171.2Gbit/s, is shown for both 271 and 2151 PRBS. The rf spectra before and after multiplexing are measured in each case and show a suppression ratio of >30dB, exhibiting the expected PRBS spectral characteristics.
