“…G. Singh et al [20] worked on the electronic equalization technique for mitigating the effect of dispersion. Decision feedback equalizers were utilized as a dispersion compensator for four channels, each of them having a bit rate of 10 Gbps, thus, making it a 40-Gbps transmission rate.…”

With the growing demand for usage among Internet users, inventions related to increase in the capacity and bandwidth of transmission channels are more significant nowadays. This continuously growing demand can be fulfilled by using the optical fibre for transmission of signals instead of the wireless mode of transmission, due to the less nonlinearity present in the optical fibre. As every available mode has its own shortcomings so does the optical fibre. It suffers from dispersion and other linearities when long-distance transmission is considered. Hence, the field of invention is associated with the compensation of dispersion in optical fibre communication at higher bit rates of 50-80 Gbps for longer distances of 120 km. After their compensation, comparison of two photodiodes, that is, pin diode and avalanche photodiode has been done at these distinct bit rates in order to achieve the best suited photodiode. After the complete analysis of simulations in terms of quality factor and bit error rate, it has been observed that at distinct bit rates of 50-80 Gbps, the simulation model using avalanche photodiode exhibits superior performance to that of the pin diode. The comparison results show that the performance of the avalanche photodiode is around 11% better than the pin diode.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Space division multiplexing, in conjunction with wavelength division multiplexing, is a powerful mechanism that increases spatial channels significantly in a single optical fiber. Spiral Phased-Laguerre-Gaussian (SP-LG) modes indicate that they effectively reduce mode coupling, thereby increasing the channel response and performance positively. However, mode-coupling influence optical fiber system leads to inter-symbol interference (ISI) between the channels and reduces both capacity and distance. In this paper, we apply the SP-LG modes in a space wavelength division multiplexing over a few-mode fiber system. The results demonstrate significant improvements in reducing channels effects and ISI. The performance evaluations are based on the bit-error-rate (BER), eye diagram and spectrum analyzer.
