Performance evaluation for 2R burst mode optical regenerator cascades in presence of co-channel phase uncorrelated crosstalk

Performance evaluation of burst mode 2R optical regenerators (BM-OR) cascades impaired with co-channel phase uncorrelated (interferometric) crosstalk is given. BMOR, unlike continuous mode, OR can handle the large power variations of the incoming packets. Bit error rate is evaluated along a cascade of identical BMORs, interspersed with potentially heterogeneous inter-regenerator links. Interferometric crosstalk can occur due to multipath signal propagation and/or imperfect filtering. The impact of signal to crosstalk ratio on the performance of this system is investigated for different nonlinearity degree of the optical reshaper, in case of low and high average packet power.
