AB - Abstract. The impact of the optical multiplexing/demultiplexing filter on ultradense wavelength-division multiplexing transmission based on polarization-multiplexed quadrature phase-shift keying (PM-QPSK) modulation at the Nyquist spectral efficiency limit is studied through simulations. We analyze 10 × 111 Gbit / s PM-QPSK systems with baud-rate channel spacing for both back-to-back and long-haul nonlinear transmission cases. We show that, although a higher-order filter generally leads to better system performance at the optimal filter bandwidth, this benefit comes at the cost of reduced tolerance to variations in filter bandwidth and center-frequency shifts.
