中文摘要：

我们为波长部门 multiplexing 建议单个 feeder 纤维体系结构被动光网络(WDM-PON ) 基于直接调制了啁啾管理激光(电流型逻辑) 。从激光的 downlink (DL ) 信号产量被变换成 return-to-zero (RZ ) 用脉搏 carver 的微分阶段移动信号。下游的信号为在上游的使用紧张调整技术作为一个搬运人被再使用。模拟结果为 uplink (UL ) 与可以忽略的力量惩罚和改进接收装置敏感每隧道以 10 Gbit/s 的对称的数据率显示出无差错的性能，在 25 km 标准上单个模式的纤维(SSMF ) 。一个便宜、减少的电路网络图案与微分编码器和一个外部调节的人的消除在单个 feeder 纤维上被实现。

英文摘要：

We propose the single feeder fiber architecture for wavelength division multiplexing passive optical network （WDM-PON） based on directly modulated chirp managed laser （CML）. The downlink （DL） signal output from the laser is converted to return-to-zero （RZ） differential phase shift signal using a pulse carver. The downstream signal is reused as a carrier for the upstream using intensity modulation technique. Simulation results show the error-free performance at symmetric data rate of 10 Gbit/s per channel with negligible power penalty and improved receiver sensitivity for the uplink （UL）, over 25 km standard single-mode fiber （SSMF）. A low-cost and reduced circuitry network design is implemented on a single feeder fiber with the elimination of differential encoder and one external modulator.
