Abstract :
Nonreturn-to-zero (NRZ)- and return-to-zero (RZ)-transmission formats are investigated for 1.55 μm 40 Gb/s fiber grating dispersion compensated standard fiber transmission. The RZ-format is shown to give a twofold increase in transmission distance compared with the conventional NRZ-format. In addition, a larger power margin is obtained at the expense of a reduced dispersion tolerance. System guidelines are proposed relating the pulse width, equalizer spacing, input power and maximum transmission distance. The results are compared with prior theoretical works at 40 Gb/s using equalizer fiber and optical phase conjugation
