1.28 Tbit/s single-polarisation serial OOK optical data generation and demultiplexing

A 1.28 Tbaud data signal is demonstrated, which is the highest symbol rate yet reported. The data signal is formed by optical time-division multiplexing of 128 data channels at 10 Gbit/s OOK in a single polarisation. The generated 1.28 Tbit/s data signal is demultiplexed in a nonlinear optical loop mirror, resulting in error-free performance with a BER < 10 -9 for all 128 demultiplexed channels.
