Crosstalk entre canais é um dos fatores limitantes em sistemas ópticos multicanais. Este artigo apresenta uma análise teórica do desempenho da taxa de erro de bits (BER) de sinais de chaveamento de fase em quadratura (QPSK) e modulação de amplitude em quadratura (QAM) influenciados por múltiplos canais de diafonia. A distribuição de campo de múltiplos canais de diafonia no mapa da constelação é calculada. O BER do sinal QPSK/QAM, ao qual a luz de diafonia é sobreposta, é então avaliado para um número variável de canais de diafonia sob a condição de que a potência total de diafonia seja constante. Os resultados confirmam quantitativamente que à medida que o número de canais aumenta, a degradação do BER causada pela luz crosstalk se aproxima da causada pela luz de ruído gaussiana. Confirma-se também que as degradações causadas pela luz crosstalk e pela luz gaussiana são semelhantes para sinais QAM de modulação de alto nível.

Abstract: Inter-channel crosstalk is one of the limiting factors in multichannel optical systems. This paper presents a theoretical analysis of the bit-error-rate (BER) performance of quadrature phase shift keying (QPSK) and quadrature amplitude modulation (QAM) signals influenced by multiple crosstalk channels. The field distribution of multiple crosstalk channels in the constellation map is calculated. The BER of the QPSK/QAM signal, onto which the crosstalk light is superimposed, is then evaluated for a varying number of crosstalk channels under the condition that the total crosstalk power is constant. The results quantitatively confirm that as the channel number increases, the BER degradation caused by crosstalk light approaches that caused by Gaussian noise light. It is also confirmed that the degradations caused by crosstalk light and Gaussian light are similar for QAM signals of high-level modulation.
