Abstract:
Analysis is presented for an optical communication channel using seven core homogeneous Multicore Optical Fiber (MCF) considering the effect of coupling among the cores. The crosstalk due to inter-core coupling affects the performance of the channel in terms of Bit Error Rate (BER). Analysis is further extended to find the output of the MCF with given signal power taking into consideration the crosstalk with varying core to core distance (pitch), core radius and relative refractive index contrast at a given data rate in terms of Signal to Cross Talk plus Noise Ratio (SCNR). We have analyzed the coupling coefficient which measures the crosstalk caused by inter-core coupling in the homogeneous MCF. The crosstalk power and performance deterioration in terms of Bit Error Rate (BER) in an optical communication link of homogenous seven core MCF have also been evaluated and presented in this paper. The outcome of this research work will find its use in designing fiber optic system with homogeneous MCF.
