摘要: A multimode optical fiber comprises a central core having an alpha profile, a depressed cladding having a portion in continuity with the alpha profile of the central core and a stepped portion, and an outer cladding. The alpha profile is obtained by co-doping at least two dopants. The variation in concentration of each dopant and its derivative in relation to the fiber radius are continuous. A multimode fiber for Ethernet optical system with an improved bandwidth is thus obtained.
摘要翻译: 多模光纤包括具有α轮廓的中心纤芯,凹陷的包层具有与中心纤芯的α轮廓和台阶部分连续的部分和外包层。 通过共掺杂至少两种掺杂剂获得α分布。 每个掺杂剂及其衍生物相对于纤维半径的浓度变化是连续的。 因此获得了具有改进带宽的以太网光学系统的多模光纤。
