The aim of this paper to find best suited filter for given photo detector i.e APD and PIN for the suppression of noise in the proposed optical system. This paper also analysis the effect of SOA for noise reduction in the optical communication system. It is concluded that APD photodiode gives a better Performance in given optical system in comparison with PIN photodiode. Low pass Bessel filter shows the best performance among the other filters at 1310 nm wavelength. Bessel filter provides constant group delay. Eye opening height is more in Bessel filter. It gives minimum Bit error rate in received signal. Semiconductor optical amplifier reduces the noise in optical system. It improves the quality of received signal. It provides lower bit error rate upto 20 km optical fiber.

Abstract


The aim of this paper to find best suited filter for given photo detector i.e APD and PIN for the suppression of noise in the proposed optical system. This paper also analysis the effect of SOA for noise reduction in the optical communication system. It is concluded that APD photodiode gives a better Performance in given optical system in comparison with PIN photodiode. Low pass Bessel filter shows the best performance among the other filters at 1310 nm wavelength. Bessel filter provides constant group delay. Eye opening height is more in Bessel filter. It gives minimum Bit error rate in received signal. Semiconductor optical amplifier reduces the noise in optical system. It improves the quality of received signal. It provides lower bit error rate upto 20 km optical fiber.
