Abstract

We have numerically evaluated the transmission performances of digital backward propagation (DBP) algorithms based on the step-size selection methods: (a) constant step-size based modified DBP (M-DBP) and (b) logarithmic step-size based DBP (L-DBP). The nonlinear tolerance of homogeneous dispersion un compensated fiber links are compared in 224 Gb/s DP-16QAM transmission over 656 km of diverse fiber types, i.e., standard single mode fiber (SMF), non-zero dispersion shifted fiber (NZDSF), large effective area pure-silica-core-fiber (LA-PSCF), large effective area fiber, and true wave classic. In the case of homogeneous fiber links, LA-PSCF exhibits higher non linear threshold and gains 32% more transmission distance as compared with SMF by employing M-DBP, while we have observed an additional 13% increase in transmission distance by employing L-DBP.
