Performance of improved X-axis auto-alignment and detection for single-channel FSO system

Performance of improved X-axis auto-alignment and detection for single-channel FSO system A precise alignment between point-to-point free space optical (FSO) networks is crucial in order to maximize the performance of data transmission. A sway or low-frequency vibration of FSO base station can affect line-of-sight quality and hence may lead to the occurrence of higher BER.

The receiver base station was fed with pulsed signal laser from a tunable laser source with a central wavelength of 1550 nm. The detection mechanism responds from an analog input signal received that corresponds to the X-axis direction of transmitter vibration. The detection performance of the system was observed by using two approaches: auto-searching of artificial intelligence (AI) detection with stop command and without stop command.

Abstract

A precise alignment between point-to-point free space optical (FSO) networks is crucial in order to maximize the performance of data transmission. A sway or low-frequency vibration of FSO base station can affect line-of-sight quality and hence may lead to the occurrence of higher BER. Therefore, the work presented in this paper is to demonstrate an improved auto-alignment single-channel FSO transmission system at X-axis detection area. The receiver base station was fed with pulsed signal laser from a tunable laser source with a central wavelength of 1550 nm. The detection mechanism responds from an analog input signal received that corresponds to the X-axis direction of transmitter vibration. The detection performance of the system was observed by using two approaches: auto-searching of artificial intelligence (AI) detection with stop command and without stop command. The obtained results indicate that the bit sequence of the pulsed signal has low loss by implementing the auto-searching of AI detection with stop command features and hence improves the efficiency of the overall FSO transmission system.
