In the past two decades, transfer of data can be possible with the combination of radio frequency and optical wireless communication (OWC) system. An alternative to radio frequency and fiber optic communication system is an OWC. Optical wireless Communication network have high data rate, license free spectrum, high immune to electromagnetic interference, low power and cost of optical components used. In this paper we have designed a WDM-OWC system for a range of 800 Km. Different simulation module like power allocation and scheduling have been performed on WDM-OWC. With Power allocation in which Q-factor and output power increases, whereas BER decreases other module is scheduling of OWC and it is found that 100 GHz of frequency spacing at a wavelength of 1550 nm is the best efficient in terms of Q-factor and BER.
