A polar code over One-Coincidence-coded optical code-division multiplexing (OCDM) network is proposed, which is suitable for the multi-access optical fiber network. The excellent error correction ability of Polar code was applied to build a low error rate performance of network system. The proposed architecture not only supports lots of users by OCDM technology with spectral amplitude coding scheme to eliminate multiple-access interference, but also support that burst traffic at the same time of data transmitting by few users. The commutation channels will divide into two opposing channel quality, information channel and frozen channel by channel polarization of polar code. The buffer channel is created to support burst user, and it is build-in in information channel. Simulation results show that the proposed architecture can improve the system performance, compared with uncoded network. The proposed algorithm has better bit error rate performance.

提出了一种单重编码光码分复用（OCDM）网络上的极地码，它适用于多址光纤网络。利用Polar码优异的纠错能力，构建了网络系统的低误码率性能。所提出的体系结构不仅通过OCDM技术以频谱幅度编码方案来支持大量用户，从而消除了多址干扰，而且还支持少数用户在传输数据的同时突发业务。通过极性码的信道极化，换向信道将分为两个相对的信道质量，即信息信道和冻结信道。缓冲区通道是为支持突发用户而创建的，它是内置在信息通道中的。仿真结果表明，与未编码网络相比，该架构可以提高系统性能。该算法具有更好的误码率性能。
