提出了一种基于网状聚合物波导结构的光背板，实现了板对板的高速光互连。这种多模聚合物波导的平面阵列可以在装有光发射器和接收器阵列的服务器线卡之间提供无源严格无阻塞链路。该架构为电子背板面临的带宽限制提供了可扩展和低成本的解决方案，适用于PCB集成。报告的背板演示器使用100个波导矩阵，每个波导具有10gb /s的操作能力，在多播模式下互连10个卡，总容量为每秒1太比特的聚合数据速率。背板演示器的特性表明，对于多模光纤输入，链路损耗为2至8 dB，串扰值低于- 35 dB。在10 Gb/s的误码率为10−9的情况下，实现无差错数据传输，功率损失仅为0.2 dB。此外，即使在使用最坏的最高损耗链路时，也可以实现背板上千兆以太网链路的无损运行。
An optical backplane based on a meshed polymer waveguide architecture enabling high-speed board-to-board optical interconnection is presented. This planar array of multimode polymer waveguides can provide passive strictly non-blocking links between server line cards fitted with optical transmitter and receiver arrays. This architecture offers a scalable and low-cost solution to the bandwidth limitations faced by electrical backplanes and is suitable for PCB integration. The reported backplane demonstrator uses a matrix of 100 waveguides each capable of 10 Gb/s operation to interconnect 10 cards for a total capacity of a terabit per second aggregate data rate in multicast mode. Characterisation of the backplane demonstrator reveals low link losses of 2 to 8 dB for a multimode fibre input and crosstalk values below −35 dB. Error free data transmission at 10 Gb/s is achieved with a power penalty of only 0.2 dB at a bit-error-rate of 10−9. Additionally, lossless operation of a Gigabit Ethernet link over the backplane is achieved even when using the worst-case highest loss links.
