We demonstrate a novel distributed fiber Raman amplified bus topology used for WDM transmission over 35 km of single-mode fiber by use of a multiwavelength Raman pump laser and eight Fiber Bragg gratings (FBGs). This topology reduces the number of addressing wavelengths needed at the head of the bus. Furthermore, by relocating the FBGs' wavelengths of a first section, it is obtained power transparency at the end of the overall bus, without requiring any additional pump source. We show how the topology allows the received powers from the first section sensors to be equalized and partially amplify the overall network. We investigate how the performance depends on the launched pump power. Results obtained with this new configuration are compared with those achieved in a previously reported optically amplified bus topology.
我们展示了一种新型的分布式光纤拉曼放大总线拓扑结构，该结构通过使用多波长拉曼泵浦激光器和八个光纤布拉格光栅（FBG），用于在35公里的单模光纤上进行波分复用（WDM）传输。这种拓扑结构减少了总线前端所需的寻址波长数量。此外，通过重新定位第一部分FBG的波长，在总线末端实现了功率透明，而无需任何额外的泵浦源。我们展示了这种拓扑结构如何使来自第一部分传感器的接收功率得以均衡，并部分放大整个网络。我们研究了性能如何依赖于发射的泵浦功率。将这种新配置获得的结果与先前报道的光放大总线拓扑结构所取得的结果进行了比较。
