| Abstract(in English) | We have demonstrated 64～512 QAM coherent optical transmission using a C_2H_2 frequency-stabilized fiber laser and an OPLL circuit. In such a ultra multi-level transmission, compensation for impairments due to fiber dispersion and nonlinearity plays a very important role. As a highly precise compensation scheme, a back propagation method of the nonlinear Schrodinger equation has been proposed. We applied this scheme to a single-polarization, 10 Gsymbol/s, 64 QAM transmission and demonstrated the impairment compensation both numerically and experimentally. |
