Investigations of Transmitted Power in Intersatellite Optical Wireless Communication

Abstract

The intersatellite optical wireless communication link is designed and simulated for performance characterization. In IsOWC link two parameters mainly bit rates and transmitted optical power is adjusted. The paper investigates the effect of transmitted power on link range and minimize transmitter power for bit rates of 0.008, 0.08, 0.8 and 8 Gbps. Maximum link range IsOWC is examined for transmitted powers of 5, 10, 15 and 20 dBm. This paper examined 8 channel IsOWC link and we calculate the minimum transmitted power for 8 channels in IsOWC link. It is observed that for lower data of 8 Mbps data rates we need less power for successful communication and for higher data rates of 8 Gbps we need large transmitted power at transmitter of IsOWC. Reduction in laser power could improve overall system performances and cost.
