Since there are a large number of LEDs deployed or used as well, LED also applicable for establishing Visible Light Communication (VLC) so it can used for dual purpose of lighting and data communications. VLC and fiber optics works the same way, but VLC using free space as its transmision medium and its carrier information is in visible light spectrum with wavelength that operate in 400 – 700 nm as indoor lightning. The design that used in this study is using simulation as media to do performance analysis of VLC systems based on wavelength that works on it. The wavelength that used are 400 nm, 550 nm, and 700 nm. Optisystem software is used as simulation media with scenario LED as transmitter and PIN photodiode as receiver. The analysis results obtained from the performance of VLC using LEDs as a light source are influenced by the magnitude of the wavelength and distance.. The best performance with a distance of 0.5 m was obtained at 400 nm with a Q-factor value 9,15304 and BER 1,54 ×10−20, at 550 nm with a Q-factor 9,15181 and BER 1,56×10−20, whereas at a wavelength of 700 nm, the smallest Q-factor obtained is 9,15028 and bigger BER 1,58×10−20. The farthest range that can be achieved by the system is obtained at a wavelength of 400 nm as far as 5.5 m, and the 550 nm as far 5 m, and the shortest at a wavelength of 700 nm as far as 4 m.
