Abstract
A comprehensive study is presented to assess the performance limitations of an optical multicore fiber (MCF) communication system due to crosstalk with on-off Keying (OOK) modulation scheme. The expressions of the signal power at the output of the different cores of the MCF with excitation to any one of the cores is found out along with the crosstalk due to coupling among the cores. Finally, the expression for Signal to Crosstalk plus Noise Ratio (SCNR) at the output of the excited core of the MCF is found. The Bit Error Rate (BER) for a given input power is then determined numerically for given data rate and different MCF parameters and transmission distance. The outcome of this research work will be useful to design fiber optic system with Multi-core Multi-mode fiber running at BER comparable to single mode fiber links.
