Abstract
Optical time division multiplexing - wavelength division multiplexing (OTDM-WDM), intensity modulation (IM) systems employing optical amplification and dispersion management (DM) are analyzed. Interchannel nonlinear effects present the input power limit to system performance. Therefore, a lumped DM system performed better than a fully inline DM system through reduction of coherent channel interaction. With proper channel spacing, all demultiplexed OTDM channels and the multiplexed signal show the same performance.
