Due to the significant need for modern technologies to meet the growing requirements of wide bandwidths, high levels of security, and high speeds. Considered Light fidelity is a future technology optical WC system that employs VL to transport data in open space. The end-user has employed VLC based on (LEDs). This technique provides a high data transfer rate, higher security, and less interference with other radio frequencies. This study investigates Li-Fi System Performance based on OCDMA/FOS under Effective Weather conditions on L-band frequency. LI-FI technology faces many challenges in maintaining system performance owing to the rise in user numbers and the different weather conditions. This causes the system performance to decrease in BER, Q-factor, power, etc. and maintains good security at the lowest possible costs and the best results. Proposed system, in addition to measuring the frequency filtering amount used in the proposed system, The results showed a significant improvement using the proposed technique, where the system achieved the error bit rate in clear weather from 3.93 * 10 -28 to 2.5 * 10 -24 , and also in dusty weather, it achieved from 1.7 * 10 -28 to 8 * 10 -23 in addition to that The amount of frequencies filtering in UFBG This means that the minimum amount to use the filter feature is1.2nm. Suggested design has proven its ability to maintain acceptable performance in end-user in light of the increase in the number of users.

Nowadays the technological advancement of the information transmission is developing very rapidly and it becomes necessary to achieve a high speed in the transmission of data as well as higher data rate. Developments in optical communication systems address these needs. However, despite all the features and advantages of optical communication systems, the dispersion is still the main challenges. In this paper and to this end, fiber Bragg grating (FBG) is used in order to overcome the dispersion issue in the wavelength division multiplexing (WDM) transmission system. The WDM transmission system is simulated using the advanced tools of Optisystem 13. The simulation program was used at a speed of 15 Gbits/s with 50Km optical fiber length based on the different input design parameters such as input signal power, optical fiber length and attenuation coefficient. In addition, the output performance parameters are discussed in terms of quality factor (Q-factor) and eye diagram. Moreover, a comparison between the proposed design and previous related works is presented.

Optical communication systems introduced paradigm shift in the forte of data transmission at higher speeds and over longer distances where, on contrary electrical transmission systems failed due to higher amplitude degradation, interferences and lower bandwidths. However, pulse width increase (PWI) in the optical fiber limits the overall distance reach and also introduces more bit errors which needs to addressed. So far, pulse width shortening fibers (PFs) and fiber Bragg grating (FG) used individually in most of the reported studies, however pulse width shortening (PWS) took either high cost (in PFs) or lower PWS efficiency (PWSE) (in FG). Therefore, in this research manuscript, we made emphasis on the combined PWS effects of diverse techniques such as optical phase conjugation (OC), FG and PFs in ultra-dense wavelength division multiplexing (WDM) system. Total link length of 400 km has been covered in 128 channels ultra dense wavelength division multiplexing (UDWDM) system at 10 Gbps by incorporating diverse combined organized placements of FG, OC and PFs such as FG-PF, OC-PF and FG-PF-OC. Results revealed that economical and maximum PWSE arrangement for proposed system is FG-PF-OC.
