Abstract
•A frequency interleave scheme is applied to WDM multicore transmission systems.•The spectrum filtering effect at the electrical stage at a receiver is taken into account.•Numerical simulations quantitatively show the effectiveness of the present scheme.
This paper describes a frequency interleaving scheme applied to WDM multicore fiber transmission systems. By shifting channel frequencies between neighboring cores, spectral overlap of inter-core crosstalk channels onto signal channels becomes small, and signal degradation due to the crosstalk is reduced. The effectiveness of the scheme is numerically demonstrated for QPSK and 16QAM signals in a conventional WDM system and duo-binary super-Nyquist WDM systems.
