Orthogonal time-frequency domain multiplexing (OTFDM) enables ultra-wideband high-
spectral-efficiency multicarrier transmission without relying on optical filters for multiplexing/
demultiplexing of subchannels. Impact of tight filtering on OTFDM signal is investigated,
assuming bandwidth narrowing in wavelength-selective switching networks.
