摘　　要：本文设计和实现了具有 PCI总线峰值带宽传输能力的光互连网络接口卡。采用可编程门阵列实现硬件路由和同步流水线传输以减小数据包在网络中的通信延迟。为扩展网络规模 ,采用波分复用技术实现了双波长环网。通过无源光学器件实现双波长信号的合波和分束 ,通过探测器选择接收不同波长的光信号以实现波长路由。In this paper, an optical network interface card with PCI bus peak-bandwidth transmission rate has been designed and implemented. Hardware routing and synchronous pipelining transmission have been accomplished to decrease communication latency. Dual-wavelength rings have been designed with wavelength division multiplexing to expand the network scale. Optical signal coupling and splitting are achieved through all-passive components. Wavelength routing is achieved by optical detector, which can selectively receive optical signals with different wavelengths. This network structure can be applied to multi-wavelength rings.
