Abstract—The development of digital optical communications systems at high flow rates (NX40Gbit/s) and wavelength division multiplexed (WDM) reveals new issues such as the need to compensate the chromatic dispersion at higher levels, the onset of effects the polarization dispersion (PMD), the greater relative importance of intra-channel nonlinearities, weakening the clearing. Conventional modulation of the optical power of all or nothing (On-Off Keying) cannot handle all these challenges and specific modulation formats (duobinary, DPSK ...) are envisaged to overcome the vagaries of broadband transmission. In this paper we study some aspects of modulation formats that meet these requirements transmission.
