随着接入网对宽带的要求越来越高，WDM-10GEPON 将成为下一代无源光网络的重要解决方案。本文提出了一种支持对称10Gbit/s双向传输的 WDM-10GEPON接入网系统方案，并且实现了该方案上行传输链路的设计与制作。系统采用10G XFP 光收发器完成光/电信号的转换，然尔，10G电信号超出了系统FPGA开发板可以处理的数据速率范围。因此，本文根据IEEE802.3av中物理介质接入子层(PMA)设计了高速信号串并转换接口电路，实现了10G-622M的复用和解复用。电路的设计和实现是上行传输链路的关键技术和难点，它包括的模块主要有：10G-SerDes 串并转换模块，时钟模块，控制模块和电源模块。最后，我们对电路板进行性能测试，实验结果表明电路能够较好的完成预期功能。

With the increasing demand for bandwith of access network , WDM-PON becomes the major solution in the next generation of PON.This paper proposes a scheme of WDM-10GEPON supporting symmetrical 10.0Gbps data rate and implement the uplink of this system. We make 10G XFP perform the function of photoelectric conversion. However, the electrical signal 10Gbit/s from XFP optical transceiver is too high for FPGA to handle. To solve this problem, we design a circuit supporting the 10G-644Mbit/s Demux and 644M-10Gbit/s Mux which is the key technical in the physical layer design of this uplink. This circuit includes the following modules:10G-SerDes Parallel/Serial Conversion Module, Reference Clock Module, Control Module and Power Module. At last the whole system realizes the function expected and worked well in the test mode of BIST.
