Abstract

Developments in the technology sector are currently experiencing rapid progress, especially in data transmission technology. The increasing need for fast data traffic in the telecommunications sector requires technology that can send data quickly. Optical fiber has the speed of receiving and sending data at 2.5 Gbps while FSO has a speed of up to 100 Gbps but this depends on Wavelength, the modulation technique used and the distance of the telescope between the transmitter and receiver. The speed of receiving and sending data also depends on the Quality (Q) of the signal, the greater the value of Quality (Q) of the signal, the better the Quality of the signal. FSO is an optical communication system that uses the atmosphere as its propagation medium and Optical Fiber uses silica as its propagation medium. Therefore, in this paper, a performance analysis of Free Space Optics (FSO) and Single Mode Fiber is carried out based on the Quality Factor and Bit Error Rate (BER) of a signal that is carried out using Optical System simulations with a wavelength of 1310 nm, 1380 nm, 1550 nm, 1550 nm and 1560 nm, with 1 km, 3 km and 5 km, respectively. Then, analysis uses an Eye Diagram to analyze the output signal and compare the Factor Q and Bit Rate Error (BER).
