摘要

为了提高能耗和低成本系统的传输容量,提出并研究了使用模式 0 和模式 1 的模式划分多路复用(MDM)技术。在下一代无源光网络和自由空间光学(NGPON-FSO)集成双向系统中,在 FSO 光纤链路损伤的影响下,使用每种 MDM 模式以每信道 10 Gbps 的传输速率传输一对 8 个下行和上行波长。仿真结果表明,在不利的湍流效应下,1 千米 FSO 和 100 米多模光纤的接收功率为 -21.2 dBm,功率损失为 0.2 dB。在阈值为 10-3 的情况下,该系统的 FSO 链路传输距离和光纤传输距离分别为 150 千米和 600 米。此外,数学分析显示,拟议系统的接收器灵敏度和分光器功率预算分别为 42 dBm 和 18 dB。与其他现有系统相比,该系统具有最佳性能。

Investigation of 16 × 10 Gbps mode division multiplexed enabled integrated NGPON–FSO architecture under wired-wireless link losses
To enhance the transmission capacity for energy consumption and low cost system, mode division multiplexing (MDM) using mode 0 and mode 1 is proposed and investigated. A pair of eight downlink and uplink wavelengths is transmitted by using each MDM mode in an integrated bidirectional next generation passive optical network and free space optics (NGPON–FSO) system at 10 Gbps per channel transmission rate under the impact of FSO–fiber links impairments. Simulation results indicate that received power of −21.2 dBm with 0.2 dB power penalty can be obtained over 1 km FSO and 100 m multimode fiber under unfavourable turbulent effects. The system provides extended FSO link range, and fiber range of 150 km and 600 m respectively at threshold limit of 10−3. Besides, the mathematical analysis depicts the receiver sensitivity and splitter power budget of 42 dBm and 18 dB, respectively, for the proposed system. The system offers finest performance than other pre-existing systems.
