Abstract:The transmission performance of three signaling formats in long-haul ultra-dense wavelength division multiplexed systems is investigated numerically. The signaling formats are the single-sideband duobinary-carrier-suppressed return-to-zero (SSB-DCS-RZ), the SSB alternate mark inversion RZ, and the bandwidth-limited phase-shaped binary transmission (BL-PSBT). After optimizing the bandwidths and detunings of the optical multiplexer and demultiplexer, the dispersion map is also optimized, and the dispersion and n… Show more
