摘　　要：通过研究开放性可重构光分插复用器(Open ROADM)标准中OFEC码的结构和编译码算法,确定了影响OFEC码算法的性能和实现复杂度的关键参数,并通过业界速率最高的300 Gbit/s现场可编程门阵列(FPGA)验证平台,对不同译码方案在输出误码率为10-15的性能进行了验证和误码平层分析,对OFEC码在超低误码率下的性能进行了准确评估。Through studying open forward error correction code(OFEC)code structure and encoding/decoding algorithm in open reconfigu-rable add drop multiplexor(ROADM)standard,the key parameters that influence OFEC performance and implementation complexity are determined.Employing state-of-theart field programmable gate array emulations platform with a record 300 Gbit/s throughput,the performance of different decoding schemes is evaluated,and the error floor is analyzed at a bit error ratio below 10-15,which makes the performance evaluation more accurate.
