【摘要】 在WDM PON中,为了使各ONU能通过多个光信道传输数据分组,在ONU需配置可调谐光发射器,而调谐时间的长短不仅与光发射器的成本密切相关,而且对网络吞吐率、时延等参数有较大影响。通过调整光信道分配方法,当光发射器具有较长调谐时间的情况下,使网络参数获得较大改善。更多还原

【Abstract】 In order to transmit packets through different optical channels upstream, a tunable transmitter is needed at ONU in WDM PON. The cost of tunable transmitter is dependent on its tuning time, which affects the throughput and delay of the network deeply. The arrangement of optical channels has been adjusted to improve the throughput and delay of the network when the tunable transmitter has a great tuning time.更多还原
