Abstract:
The impact of MPI in all-Raman multi-span dispersion-compensated links was studied. D+/D- and D+/D-/D+ compensation schemes were considered, for both IMDD and DPSK. OSNR penalties were calculated for several system configurations. Our analysis confirmed that the D+/D-/D+ OSNR penalty is typically much less than that of the D+/D- scheme. We then estimated the increase, due to MPI, in the number of spans required to satisfy a target OSNR for a given total link length, taking into account Kerr nonlinearities. Somewhat unexpectedly, it turned out that such increase can be very significant (up to 15-20%) with the D+/D- scheme and lower but non-negligible (5–10%) with the D+/D-/D+ schemes. DPSK is typically less impacted than IMDD across all configurations.
