This paper analyses and achieves the accurate computational expression of nonlinear phase noise cos(Δφ) in DPSK
receivers using optical Mach-Zehnder interferometer (MZI) demodulation and balanced detection of 40Gbit/s system. It
had been used in the BER computation expression considering all the noises to achieve a final accurate computation
expression of BER.
We experimentally demonstrate a multi-pulse all-optical time domain continuous Fourier transformation (MOFT) based
on a time lens. With two of MOFT devices, one is at transmitter, the other is at receiver, we experimentally show a
successful all-optical OFDM fiber transmission system with 20Gbit/s 200km transmission without any dispersion
In this paper, the influence of the burstiness of IP packets on nonlinear effects in dynamical optical Networks such as
XPM (cross phase modulation) and FWM (four-wave mixing) are investigated and simulated by adding revised Poisson
distributed traffic parameters in the nonlinear Schrödinger equation (NLSE).From simulations, different eye diagrams
with different IP traffic loads, different fiber input light powers are achieved. When the input power is bigger than 3 dBm
with 40 channels or bigger than 5dBm with 16 channels, the effect of IP bursty traffic could depredates eye diagrams
dramatically. The research results are useful for router finding and system design.
