Caracterização e análise de desempenho dos amplificadores ópticos Raman discretos em sistemas de comunicações ópticas na banda O
| Resumo: | The optical amplifier has improved the optical communication systems because they lead to an increase in transmission capacity of medium and long haul optical systems, with technological advantages over electronic regenerators. The optical amplifier are relatively simple to deploy and can be used in optical links without any troubles regarding signal transmission rate improvement and signal modulation changes, as a consequence of these issues they can substitute the electronic regenerator enhancing security with low operation cost. The CWDM systems multiplex optical wavelength with a low cost in metropolitan networks. It was developed to connect backbone networks to metro core and edge networks with cost saving over DWDM systems but lower transmission capacity. We have developed and characterized in our research a discrete Raman amplifier for operation in O band. We connected the amplifier in a point to point CWDM in order to analyze the gain on the system transmission capacity and the impairments that appears in the system. Working with a eight channel CWDM in O band, modulated with 2.5 Gbit/s, we have demonstrated that we can use a discrete Raman amplifier in single configurations, pre amplifier, booster and line amplifier and shared configuration with booster and pre amplifier to increase the transmission capacity that means, increase the length of the optical link. We have increased in 110% the length of the optical link with a shared configuration of two amplifiers with 10 dB gain for each one. |
