“…Conclusively, tapered fiber optimizes the mode quality to achieve higher beam quality. This would produce good modes for data transmission (Ghazi, A., 2019). Similar experiments by researchers involving tapered fiber were conducted by (Mahadzir, N.A., 2021).…”

One of the main advantages of optical communication is its potential to transmit messages through the same channel via multiplexing. The concept of Mode Division Multiplexing (MDM) technology was first suggested to the telecommunication industries as a substantial solution to decrease the cost per bit of optical fiber transmission. This article aims to transmit information with less possible noise. To achieve this, multiple transverse modes are used to deliver information from the transmitter to the receiver. Our design evaluated a tapered nature that excites a total of 20 modes. In the evaluation, we applied Fourier transformation to the modes. We combined two, three and four modes to test the different complex mode mechanisms they produce in amplitude and phase.

Nonlinearities in optical fibers deteriorate system performances and become a major performancelimiting issue. This article aims to investigate the compensation of nonlinear distortions in optical communication systems based on different wavelength propagations over few-mode fiber (FMF). The study adopted Space Division Multiplexing (SDM) based on decision feedback equalizer (DFE). Various transmission wavelength of the FMF system is applied to mitigate the attenuation effect on the system. In this paper, different wavelengths (780, 850 and 1550 nm) are used in SDM. Extensive simulation is performed to assess the attenuation and Bit Error Rate (BER) in each case. The results show that the wavelength of 1550 nm produces higher power and less attenuation in the transmission. Furthermore, this wavelength produces the best distance with less BER compared to 780 nm and 850 nm wavelengths. Moreover, the validations show improvement in BER and eye diagram.

“…Different techniques like orthogonal frequency division multiplexing-FSO and wavelength-division multiplexing-FSO based system are new approach to improve the system performance with high speed and longer distance [8]. Wireless optical communication system-FSO has been studied to evaluate the effect of different weather conditions on the performance of the system [9]. Two bi-directional FSOs are compared as case study in the middle east region [5].…”

This work investigates the integration of Electrical to Optical (E/O) and Optical to Electrical (E/O) communication systems. Two ways of transition, namely, Hybrid Fiber Optic (FO) and Free Optical Space (FSO) transmission system have been proposed. This work aims to evaluate the performance of these two transition ways. FO has the optimum transmission due to its lower attenuation which can be reached to 350 km. However, for further assurance of reaching data to the receiver side a second way of transition has been investigated. FSO path has been employed under different weather conditions of clear, moderate dust, heavy dust and heavy fog. Matlab and Optisystem7 software’s have been used to simulate Optical Secure Data Transition (SDT). The results show that an optimum transmission could be obtained using FO with RGB image encryption where the Mean Square Error (MSE) reach to 9.88 ×10^7 in read channel and it can reach to 4.93 ×10^9 using Discrete Wavelet Transform (DWT).
