Abstract Different fiber amplifiers such as semiconductor optical amplifier, erbium-doped fiber amplifier and erbium ytterbium-co-doped fiber amplifier (EYCDFA) are investigated for 16×40 GB/s wavelength division multiplexing system. Various performance parameters including Q-factor, bit error rate, jitter, eye opening and eye closure are observed and analyzed. It is reported that EYCDFA is a better choice among the tested amplifiers. The proposed system is also investigated in terms of transmission distance.

AbstractIn this paper, the performance of wavelength division multiplexing-passive optical network (WDM-PON) system using the erbium-doped fiber amplifier (EDFA) is optimized and evaluated. The optimization is analyzed by finding the EDFA length range at which the output power produced are the highest and the pump power range at which the gain flatness produced are within the effective range (0.3 dB). After the optimization process, the optimized EDFA system produces the gain of 26.6±0.292 dB, noise figure of 3.82 dB and output power of 7 dBm and the system is then implemented into WDM system. The performance of WDM system is compared against the system without EDFA in terms of bit error rate (BER). Results obtained prove that the proposed system with the EDFA consistently performs better than the conventional system.

Abstract Analysis of wavelength division multiplexing (WDM) system utilizing erbium-doped fiber amplifier (EDFA) has been carried out by many researchers. In this paper, the performance analysis of 8-channel WDM system utilizing EDFA and fiber Bragg grating (FBG) combination is carried out in a wavelength band 1546–1552 nm at 10 Gbps. The performance of three apodization functions (Uniform, Gaussian and Tanh) of FBG is compared using return-to-zero (RZ) and non-return-to-zero modulation formats at fiber lengths 50, 60, 70 and 80 km. Also, the performance of FBG is compared for both aspects: with chirp and without chirp for grating lengths 5–10 mm. The Gaussian apodized and linearly chirped FBG outperformed the other two in compensating chromatic dispersion. Optimum values of Q-factor are also obtained using linearly chirped FBG with RZ modulation format at 10 mm of grating length.

AbstractThis paper aims to analyze the performance of FBG 60 channel wavelength-division multiplexing system using different optical amplifiers namely RAMAN, erbium-doped fiber amplifier (EDFA) and semiconductor optical amplifier (SOA) separately at 10 Gbps data rate up to a fiber length of 280 km. Based upon the results, the performance of the three amplifiers has been compared on the basis of multiple performance parameters. It is seen that EDFA simulates good results in terms of bit error rate (BER) up to a fiber distance of approximately 80 km and Q factor up to a distance of approximately 90 km among all the three amplifiers. However, power received is least in EDFA. RAMAN amplifier provides a better Q factor after the fiber distance of approximately 90 km and a better BER after the fiber distance of approximately 80 km compared to the other three amplifiers. SOA shows better results in terms of power received up to a fiber distance of approximately 100 km. RAMAN amplifier provides better output power after a distance of 100 km. Eye diagrams and power spectrums of the network with different optical amplifiers has also been analyzed.
