Nyquist WDM for FTTH Applications using reflective semiconductor optical amplifiers

Abstract

Castellano: En este trabajo se caracterizan SOAs reflectantes para aplicaciones económicas de FTTH. El formato novedoso de la modulación Nyquist WDM es investigado e implementado. Una mejora de la potencia del bit error está conseguido por una pre-distorsión que compense la limitación del ancho de banda del transmisor reflectante. La modulación resultante mejora la BER y la velocidad de transmisión. Además, el formato necesita menos procesamiento de la señal en comparación con OFDM, mientras alcanzan la misma velocidad de transmisión.

Una millora de la potència del bit error està aconseguit per una pre-distorsió que compensi la limitació de l'ample de banda del transmissor reflectant. La modulació resultant millora la BER i la velocitat de transmissió. A més, el format necessita menys processament del senyal en comparació amb OFDM, mentre arriben a la mateixa velocitat de transmissió.

English: In this paper reflective SOAs are characterized for cost-efficient FTTH applications. The novel Nyquist WDM modulation format is investigated and implemented. An improvement of the bit error performance is achieved by a pre-distortion that compensates the bandwidth limitation of the reflective low-cost transmitter. The resulting modulation improves the BER and transmission speed. Furthermore, the format needs less signal processing compared to OFDM while reaching the same transmission rates.
