摘要

提出了一种基于阵列波导光栅（AWG）的分组无源光互连（GPOI），用于数据中心机架内连接。AWG的波长和空间通道被充分利用，以扩大规模和提高吞吐量。AWG的每个端口通过合并/分配器与一组服务器相连。在GPOI中，互连组件为N × N AWG，可用波长为N，而服务器数量增加到N2台服务器，吞吐量将大大提高。提出Shuffle双连接，以改善由于波长竞争冲突导致的吞吐量降低。与以前的建议相比，GPOI的成本较低。对所提出的GPOI进行了验证，并通过仿真测试了信号性能，证明了该方法的可行性。

Grouped passive optical interconnection to achieve large scale and high throughput

An array waveguide grating (AWG) based grouped passive optical interconnection (GPOI) is proposed for intra-rack connection in a data center. The wavelength and space channels of the AWG are highly utilized to enlarge the scale and increase the throughput. Each port of the AWG is connected to a group of servers through a combiner/splitter. In GPOI, the interconnect component is an N × N AWG and the available wavelength is N while the number of the severs is increased to N² servers and the throughput will be much increased. Shuffle dual-connection is proposed to improve the throughput reduction from the wavelength-competing collisions. The cost of GPOI is low compared with previously proposals. The proposed GPOI is demonstrated and the signal performance is tested through simulation to show the feasibility.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
