No. of bitstreams: 1 Jair Fiuza - EE2006.pdf: 870543 bytes, checksum: 939198dd0585c5cbae3d86adf6c858cc (MD5) Previous issue date: 2006-08-29 / The performance of a distributed Raman amplifier at S - Band using the TrueWave® Reach Low Water Peak fiber in a 100km span is analyzed through numerical simulations. The manufacturer, the OFS Fitel Denmark Ap, has experimentally characterized the physical parameters of the fiber, such as, attenuation, dispersion and Raman gain efficiency at Band - S. The low fiber attenuation around pump wavelength region, around 0,34dB/km at 1370nm, allow the achievement of approximately 10dB over 70nm in the S - Band − using 4 (four) pump lasers with pump power on the order of tenth of mWatts . / O desempenho de um amplificador Raman distribuído na Banda - S utilizando a fibra óptica TrueWave® Reach Low Water Peak em um enlace de 100km é analisado através de simulações numéricas. O fabricante, a OFS Fitel Denmark Ap, caracterizou experimentalmente os parâmetros físicos da fibra óptica, tais como atenuação, dispersão, e eficiência de ganho Raman na Banda - S. A baixa absorção dessa fibra óptica na região espectral onde se localizam os lasers de bombeamento, em torno de 0,34dB/km, para 1370nm, permite a utilização de 4 lasers de bombeamento com potências da ordem de dezenas de mWatts, para garantir um ganho on-off da ordem de 10dB em 70nm (1460 a 1530nm) na Banda - S.
