到2013年，管理数据存储设备的协议数据速率将增加到超过12 Gb/s，从而对未来的数字数据存储系统施加难以管理的成本和性能负担。由此产生的性能瓶颈可以通过光学而不是电子传输高速数据来大大减少。介绍了一种新型的有源可插拔82.5Gb/s聚合比特率光连接器技术，设计和制造了一种满足严格要求的紧凑型电光印刷电路板，并提出了一种低成本、高精度的无源光组件方法。构建了一个演示平台，以评估嵌入式电光中板技术在此类系统中的可行性，包括首次演示可插拔有源光波导印刷电路板连接器。通过在262 mm × 240 mm × 4.3 mm电光中板中嵌入复合聚合物波导互连层，实现了10.3125 Gb/s的高速光数据传输。误码率小于10-12和光损耗低至6 dB，通过9个多模聚合物波导与92.8125 Gb/s的总数据带宽。
The protocol data rate governing data storage devices will increase to over 12 Gb/s by 2013 thereby imposing unmanageable cost and performance burdens on future digital data storage systems. The resulting performance bottleneck can be substantially reduced by conveying high-speed data optically instead of electronically. A novel active pluggable 82.5 Gb/s aggregate bit rate optical connector technology, the design and fabrication of a compact electro-optical printed circuit board to meet exacting specifications, and a method for low cost, high precision, passive optical assembly are presented. A demonstration platform was constructed to assess the viability of embedded electro-optical midplane technology in such systems including the first ever demonstration of a pluggable active optical waveguide printed circuit board connector. High-speed optical data transfer at 10.3125 Gb/s was demonstrated through a complex polymer waveguide interconnect layer embedded into a 262 mm × 240 mm × 4.3 mm electro-optical midplane. Bit error rates of less than 10-12 and optical losses as low as 6 dB were demonstrated through nine multimode polymer wave guides with an aggregate data bandwidth of 92.8125 Gb/s.
