Improved mitigation of self-phase modulation induced impairments in 28 GBaud phase-sensitive amplified links
Journal article, 2019

The improved mitigation of self-phase modulation (SPM) induced nonlinear impairments by the use of a multi-span dispersion map optimization in 28 GBaud phase-sensitive amplifier (PSA) links is numerically investigated. We show that a four-span dispersion map optimized PSA link provides 2.1 times reach improvement over a single-span optimized PSA link with a total nonlinear phase shift tolerance increase from 2.1 radians to 8.8 radians. Furthermore, the optimized PSA link increases the maximum transmission reach by 6.9 times compared to a single-span optimized in-line dispersion managed phase-insensitive amplifier (PIA) link and 4.3 times reach extension is achieved compared to a dispersion unmanaged PIA link.
