介绍一种采用FDM输出缓存器的光ATM交换机。该交换机有一个广播选择网络结构,使用了固定频率信道发送机和一个无源星形结构。交换机结构简单,可提供广播型交换或多点交换。解决信元争用的输出缓存器装有光纤延迟线,以便利处理大于10 Gb/s速率的信号。用具有功率补偿为2.8 dB的两路复用10 Gb/s信元实验样机进行高速交换实验已获得成功。 An optical ATM switch that uses an FDM output buffer is introduced. The switch has a broadcast selection network architecture that uses a fixed frequency channel transmitter and a passive star structure. Switch structure is simple, can provide broadcast or multi-point exchange. The output buffer, which addresses cell contention, is equipped with fiber-optic delay lines to facilitate the processing of signals at rates greater than 10 Gb / s. High-speed exchange experiments with two multiplexed 10 Gb / s cell prototypes with power compensation of 2.8 dB have been successful.
