Dispersion And Attenuation

AbstractIn this paper, we have presented a global study of simple bonds, focusing on the main limitations introduced by different optical components as laser source, fiber, optical amplifier, and optical detector. The construction of a long-distance link requires the compensation of attenuation and chromatic dispersion phenomena. Thus, it is well known that the attenuations cause the drop of the signal intensity, whereas the pulse spreading, due to the dispersion, causes the increase of the Bit Error Rate (BER) and consequently the reduction of the signal to noise ratio (SNR). In this purpose, we have calculated the quality factor (Q) issues from the noisy signal’s simulations. We have found a Q of 7.02 to a BER of 0.8 e−12. The founding results match well with fixes norms in telecommunication field.

Hybrid Optical Amplifier

We have proposed a very advanced super dense wavelength division multiplexing (SD-WDM) system using RAMANErbium doped silica fiber optical amplifier (EDSFA) hybrid optical amplifier (HOA) in this paper. Performance is evaluated in term of flattened gain and noise figure for C-band. Effect of proposed hybrid optical amplifier also compared with EDFARAMAN, EDFA-SOA and SOA-SOA HOA for the same characteristics. Best rating gain of 37.5 dB with noise figure of 5.4 dB ever recorded from RAMAN-EDSFA HOA. It is also observed that out come from SOA-SOA HOA is not acceptable in term of noise figure of 9.1 dB for 400 x 10 GB/s SD-WDM system. Keywords: SD-WDM, RAMAN-EDSFA, EDFA-RAMAN, EDFA-SOA, SOA-SOA, noise figure, gain
