A acomodação eficaz dos utilizadores será cada vez mais importante nas redes ópticas passivas (PON) na próxima década, uma vez que o número de assinantes também tem vindo a estabilizar e está a tornar-se mais difícil para os operadores de rede manter um número suficiente de trabalhadores de manutenção. Reduzir drasticamente o número de edifícios de comunicação de pequena escala e manter o número de utilizadores acomodados é uma das soluções mais atractivas para fazer face a esta situação. Para conseguir isso, propomos dois tipos de configurações de transmissão upstream sem repetidor de longo alcance para sistemas PON; (i) um utiliza um amplificador óptico semicondutor (SOA) como pré-amplificador e (ii) o outro utiliza amplificação Raman distribuída (DRA) além do SOA. Nossas simulações assumindo especificações 10G-EPON e experimentos de transmissão em um protótipo 10G-EPON confirmam que a configuração (i) pode adicionar uma fibra tronco de 17 km a um sistema PON normal com alcance de acesso de 10 km e divisão 1: 64 (alcance total de 27 km), enquanto a configuração (ii) pode expandir ainda mais a distância da fibra tronco para 37 km (alcance total de 47 km). As operadoras de rede podem selecionar essas configurações dependendo de suas áreas de serviço.

Abstract: Effective user accommodation will be more and more important in passive optical networks (PONs) in the next decade since the number of subscribers has been leveling off as well and it is becoming more difficult for network operators to keep sufficient numbers of maintenance workers. Drastically reducing the number of small-scale communication buildings while keeping the number of accommodated users is one of the most attractive solutions to meet this situation. To achieve this, we propose two types of long-reach repeater-free upstream transmission configurations for PON systems; (i) one utilizes a semiconductor optical amplifier (SOA) as a pre-amplifier and (ii) the other utilizes distributed Raman amplification (DRA) in addition to the SOA. Our simulations assuming 10G-EPON specifications and transmission experiments on a 10G-EPON prototype confirm that configuration (i) can add a 17km trunk fiber to a normal PON system with 10km access reach and 1 : 64 split (total 27km reach), while configuration (ii) can further expand the trunk fiber distance to 37km (total 47km reach). Network operators can select these configurations depending on their service areas.
