前向纠错技术在EPON中的应用研究

Forward error correction application in EPON

在EPON中引入前向纠错(FEC)技术,能有效地增加PON的光分路数和增大信号的传输距离。对于在EPON中加入FEC功能所涉及到的FEC线路综合编码、帧结构的设计以及兼容性等问题进行了分析,并进一步给出了相应的解决方案。

The application of Forward Error Correction (FEC) in EPON can improve the ratio of PON and extend the distance of transmission. This paper discusses combination of FEC coding and line coding, analyzes compatibility of system and design of frame. The paper also gives the solution to such problem.
