Abstract

With the radio frequency spectrum becoming crowded, an alternative means to wireless communication is necessary to accommodate the exponentially increasing wireless traffic demand. By employing light from LEDs as the communication channel, visible light communication systems provide an alternative to the present norms of wireless information transport. The optical transmitter in these systems blinks quickly enough that the human eye will not notice the change in light intensity, but an optical receiver can detect the on-off behaviour and decipher the information contained within. In this paper we have analyzed the performance of visible light communication using mach zhender modulator for RZ-OOK and NRZ-OOK modulation formats. We have implemented WDM (Wavelength Division Multiplexing) channel for various streams of data. The Quality Factor and log of BER values for various data rates and link distances are used to evaluate the communication system. With a maximum Q factor of 46, this system can provide 2 Gbps data throughput across a connection distance of up to 2500 m. The communication is conducted via an optical transmitter, and NRZ-OOK and RZOOK modulation studies are conducted.
