An Accurate Model for System Performance Analysis of Optical Fibre Networks with In-line Filtering

Symbol rate limitation due to optical filtering

“…Today, in-line filtering penalty is an actively discussed topic [1][2][3][4][5][6][7]. The main research methods are numerical modelling and direct experiment, so far only [6] proposes the idea of an analytical solution.…”

“…Today, in-line filtering penalty is an actively discussed topic [1][2][3][4][5][6][7]. The main research methods are numerical modelling and direct experiment, so far only [6] proposes the idea of an analytical solution. It was shown that the filtering penalty depends on the noise distribution and the biggest penalty occurs when the noise is added just before the receiver [6], hereinafter refers to the 'worst case'.…”

“…It was shown that the filtering penalty depends on the noise distribution and the biggest penalty occurs when the noise is added just before the receiver [6], hereinafter refers to the 'worst case'. Nonlinear distortions influenced by in-line filtering were also discussed in [6]. Finally, mitigation of the filtering penalty was investigated in [2,[8][9][10][11].…”

“…Section 2 contains details about the experimental setup and the BER (bit error rate) threshold influence. An analytical solution is given in section 3 where we complete the concept proposed in [6] with explicit practical expressions. Section 4 presents the comparison of results.…”
