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).
Highlights
The transmission technique used begins with copper cable networks as a transmission medium on home telephone systems and internet networks
Free Space Optics (FSO) can provide high speed from Point to Point or Point to Multipoint which is difficult to do by Radio over Fiber (ROF) technology such as optical fiber [4]
This paper studied and analyzed various optical communication channels, namely Free Space Optics and Optical Fiber from the results obtained using the Optisystem software program and the simulation results obtained
Summary
The transmission technique used begins with copper cable networks as a transmission medium on home telephone systems and internet networks. Because the copper network has a small bandwidth, the latest innovation is being developed, with wireless transmission for connections between networks using radio frequency namely Free Space Optics (FSO). FSO is a technology that uses invisible ray lines to provide optical bandwidth connections that can send and receive data, voice and video communications at high speed [4]. FSO can provide high speed from Point to Point or Point to Multipoint which is difficult to do by Radio over Fiber (ROF) technology such as optical fiber [4]. It was implemented using a laser device that could be installed inside a building or office and basically consisted of an optical transceiver with a laser transmitter and the receiving end to provide full duplex capability [11]. It does not need to excavate roads as in the case of optical fibers, large bandwidth that allows high data rates and low power consumption [2]
