Experimental and theoretical investigation of M-array pulse amplitude modulation transmission for reach extension Academic Article uri icon


  • We present here the M-array modulation scheme that enables transmission of higher data rates at the same spectral bandwidth. The results indicate that the M-array technique can be implemented. This scheme leads to a significant narrowing of the optical spectrum which, in turn, enables a significant extension of dispersion-limited links.
