基于FPGA的16E1光纤复接系统

Fiber Optical Muldex System of 16 E1 on FPGA

提出并设计了一种低成本、2～ 1 6个 E1单步复接、采用单片 FPGA实现、通过光纤传输的中小容量数字复接系统 ( FOM) ,作为光纤接入网的传输过渡产品 .在合理定义的系统帧结构基础上 ,采用 VHDL硬件描述语言和自顶向下的设计流程 ,完成了系统的核心逻辑设计 ,并用2 5万门 FPGA进行了仿真和测试 。

One cost efficient fiber optical muldex (FOM) system to transmit small or middle business as the transition of optical access production was put forward and designed. It is implemented by one step multiplexing 2 to 16E1 on FPGA. The core functions of the system were designed by top down flow in VHDL, on the ground of defining the system frame in reason. The simulation and testing of the system including the multiplexing and demultiplexing functions were accomplished on 25 million gate FPGA. The realizability of this project has been proved.
