The trade‐off between transmission performance and hardware implementation in application‐specific integrated circuits of digital backpropagation (DBP) in coherent 32 GBd polarisation‐division multiplexing 16 quadrature amplitude modulation is analysed. The reach is optimised for different DBP implementations under constraints of 16 and 28 nm complementary metal–oxide–semiconductor (CMOS) technology digital signal processing (DSP) area.
