Analysis Modulation Formats in DWDM Transmission System

  title={Analysis Modulation Formats in DWDM Transmission System},
  author={Carilyn Torruellas and WEI Jian-yi and LI Hong-an and ZHANG Xiu-tai},
In modulation and demodulation methods of the optical Differential Quadrature Phase Shift Key (DQPSK) and the different modulation formats including nonreturn-to-zero(NRZ), return-to-zero (RZ), carrier-suppressed return-to-zero(CS-RZ) are introduced, studying the different optical signals in the 40Gb/s high speed transmission system. The system is simulated in 200km optical fiber by way of dispersion compensation. It is showed that the ability of anti-dispersion and anti-PMD (Polarization Mode… CONTINUE READING
