在分组时间标度重构条件下，研究了一种基于半导体光放大器的承载波长条纹数据的交换机在短距离大容量数据互连中的容量缩放问题。现成的组件与低复杂性的控制层一起使用，以演示高容量的端到端分组路由。根据广播和选择架构的功率损失和动态范围来评估增加聚合数据速率和连接到交换结构的数量的影响。研究表明，多达10个波长复用数据通道，总容量为100 Gb/s，可以为更高的总数据速率和额外的分离器级提供足够的余量，这将在单级中实现8倍8的连接。随着商用发射机和接收机性能的提高，预计连通性将进一步提高。多径路由通过三个主机同时在同一交换结构上传输波长条纹数据包进行评估，以揭示由于多径串扰而产生的0.3-0.6 dB的损失，以及通过动态路由产生的0.4-1.2 dB的适度损失。确定了在单级低复杂度交换结构中实现每秒太比特交换性能的途径。
The scaling of the capacity of a semiconductor- optical-amplifier-based switch carrying wavelength-striped data is assessed under packet timescale reconfiguration for short- reach high-capacity data interconnects. Off-the-shelf components are used with a low-complexity control layer to demonstrate high-capacity end-to-end packet routing. The impact of increasing the aggregate data rate and the number of connections made to the switch fabric is assessed in terms of the power penalty and dynamic range for a broadcast and select architecture. Studies with up to ten wavelength-multiplexed data channels with an aggregate capacity of 100 Gb/s are shown to give sufficient margin for even higher aggregate data rates and for the additional splitter stages, which would enable 8times8 connectivity in a single stage. Further increases in connectivity are anticipated with higher performance commercially available transmitters and receivers. Multipath routing is assessed with three hosts simultaneously transmitting wavelength-striped data packets over the same switch fabric to reveal a penalty in the range of 0.3-0.6 dB due to multi- path crosstalk and a modest penalty in the range of 0.4-1.2 dB that was incurred through dynamic routing. A route to terabit-per- second switch performance in a single-stage low-complexity switch fabric is identified.
