Numa rede RoF microcelular, é estabelecido um sistema de antenas distribuídas alimentado por fibra. Cada antena remota recebe sinais de radiofrequência e transmite-os através de uma ligação de fibra ótica até uma estação central para processamento do sinal. Um sistema RoF pode ser ainda mais aprimorado através da incorporação da técnica de multiplexação por divisão densa de comprimento de onda (DWDM) para otimização da utilização da largura de banda e comunicação a velocidade ultra-alta. O presente trabalho tem como objetivo apresentar um modelo para um sistema RoF deste tipo, que funcione a alta velocidade e possua uma enorme capacidade. Após uma extensa revisão da literatura sobre o tema, concluiu-se que ainda há um longo caminho a percorrer no que diz respeito aos sistemas RoF. No processo de desenvolvimento de um sistema com enorme capacidade e maior velocidade, é necessário ter em conta restrições como o espaçamento entre canais, a interferência entre símbolos e os efeitos de mistura de quatro ondas, o que se revela um desafio.
