摘要：

The influence of the nonlinear propagation effect on three 400 Gb/s/ch(400G)optical fiber communication systems with typical modulation formats,dual-carrier 16-quadrature amplitude modulation(16QAM),single-carrier 16QAM(single-16QAM),and four-carrier quadrature phase-shift keying,are investigated.The received optical signal-to-noise ratio(OSNR),affected by the nonlinear interference noise together with the amplified spontaneous emission noise,are compared with three 400G systems and a standard 100 Gb/s/ch system by numerical simulations.Both single channel and multichannel cases are considered.Single-16QAM is found to have the best OSNR among those modulation formats.
