Abstract
There has been some interest in the Non-linear Frequency-Division Multiplexing (NFDM) in optical fibre communication systems, because it promises interference-free or weak-interference between channels in an optical routed network. NFDM scheme uses Non-linear Fourier Transform (NFT) to bring a time-domain signal into the non-linear frequency domain (NFD), where the spectra evolve in a linear manner during signal propagation in the fibre channel. The successful application of NFT relies heavily on the "channel's integrability" that is only fulfilled by an ideal distribution-Raman amplification. However, most of the optical fibre links are amplified by Erbium-doped fibre amplifiers (EDFAs). The impact of the non-integrability in NFDM networks is unclear. In such a network, one key device is the Non-linear Add-drop Multiplexer (NADM) that adds or drops channels in the NFD. Simulating such device that processes many channels simultaneously is still difficult due to a high complexity and inaccuracy of the current INFT-NFT algorithm. To get around this difficulty, we adopt a different approach to estimate the inter-channel interference (ICI) in NFDM networks.
