Análise de códigos corretores de erros aplicados a canais ópticos

This work presents a comparative study on Forward Error Correction Codes (FEC) of second and third generation for optical communication systems. The present analysis of FEC codes for optical systems takes into account the non-linear effects in the optical fiber. The code rate used in this study is close to R = 0.8 to comply with the recommendation of the Optical Internetworking Forum (OIF) which recommends an overhead of about 20 %
