“…The high carrier frequency of FSO in the range of 20 THz to 375 THz enables it to transfer data at really high rates. As FSO is offering a wide broadband service, it needs Line of Sight (LOS) communication between the transmitter and receiver [3]. It is due to the principle of light which travels in straight line.…”

Abstract. This paper presents the analysis of the effect of BER and Q-factor on free space optical communication system using the diverse wavelength technique. The visibility is gradually decreased due to attenuation effects such as weather conditions as the bit error rate increases. Despite this disadvantage, FSO performance could be further improved by using a wide range of wavelengths of the laser beam. The results show good performance for 1550 nm wavelength, where the wavelength can accommodate visibility for 6 km at link range of 1 km, and Q-factor 25 at the system performance BER = 10 -124 could improve the system by 67% compared to 850 nm and 785 nm wavelength ,which could enhance the system by only 2%. This clearly show that the superior capabilities of 1550 nm wavelength in handling attenuation problems and capability to reduce the power loss compared to 850 nm and 785 nm wavelength.

“…Besides, multiple access interference (MAI) is the major performance degradation mainly when a large number of users are occupying in the OCDMA systems. Then, the most significant consideration is the code design for decreasing contribution at the MAI to the optical power receives [6]. In OCDMA systems, there are several techniques can be implemented to eliminate MAI.…”

Abstract. This paper presents a realization of Wavelength/Time (W/T) Two-Dimensional Modified Double Weight (2-D MDW) code for Optical Code Division Multiple Access (OCDMA) system based on Spectral Amplitude Coding (SAC) approach. The MDW code has the capability to suppress Phase-Induce Intensity Noise (PIIN) and minimizing the Multiple Access Interference (MAI) noises. At the permissible BER 10 -9 , the 2-D MDW (APD) had shown minimum effective received power (Psr) = -71 dBm that can be obtained at the receiver side as compared to 2-D MDW (PIN) only received -61 dBm. The results show that 2-D MDW (APD) has better performance in achieving same BER with longer optical fiber length and with less received power (Psr). Also, the BER from the result shows that MDW code has the capability to suppress PIIN ad MAI.
