“…The assessment parameters obtained from the eye diagram include the eye-opening penalty (EOP) and quality factor (Q-factor). From the eye diagram, the Q-factor is calculated using the mean values and the standard variations of the mark (-1‖) pulses and of the space (-0‖) pulses as follows [24]. where I 1 and I 0 represent the mean values of -1‖ pulses and -0‖ pulses, respectively, which are obtained at every timing clock period, and σ 1 and σ 0 represent the standard variations of -1‖ pulses and -0‖ pulses, respectively.…”

“…where I 1 and I 0 represent the mean values of -1‖ pulses and -0‖ pulses, respectively, which are obtained at every timing clock period, and σ 1 and σ 0 represent the standard variations of -1‖ pulses and -0‖ pulses, respectively. Generally, 6 is the standard value of the Q-factor for the quasilinear system [24]. Thus, Q-factor = 6 is used as the reference value in the simulation.…”

In long-haul optical communication systems consisting of single-mode fiber spans and fiber amplifiers, such as an erbium-doped fiber amplifier, signal distortion causes performance to deteriorate because of group velocity dispersion and fiber nonlinearity. A combination of dispersion management and optical phase conjugation is an effective technique of compensating for the distortion. In an optical link configured with this combination, the dispersion map mainly affects the compensation for the distorted optical signals. Improvements in system performance have been reported for various types of dispersion maps. In this study, a symmetric type of dispersion map with respect to the midway optical phase conjugator is proposed. The effect of the proposed dispersion maps on the compensation for the distorted 24 channel × 40 Gbps wavelength-division-multiplexed signals was assessed through numerical simulation. It was confirmed that antipodal-type dispersion maps are most appropriate for the compensation, as well as for the flexibility of the link configuration.
