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. A multimode fiber for Ethernet optical system with an improved bandwidth is thus obtained.

摘要： A multimode optical fiber includes a central core having a radius (r1) and an alpha-index profile. The multimode optical fiber further includes a depressed trench, which surrounds the central core, that has a width (wt) and a refractive index difference (Δnt) with an outer optical cladding. Typically, the central core's diameter is between about 47 and 53 microns, and the depressed trench's width (wt) is between 0.5 micron and 2 microns. The depressed trench's refractive index difference (Δnt) with the outer optical cladding is typically between −4×10−3 and −1×10−3.

摘要： A method of classifying a graded-index multimode optical fiber includes taking a series of individual measurements at a single wavelength, and using the measurements to characterize the departure of the multimode optical fiber's actual index profile from the corresponding nominal index profile. The measurements, coupled with intermodal dispersion or EMB measurement, may be used to predict the approximate transmission properties of the optical fiber at wavelengths other than the measurement wavelength. It is desirable for a graded-index multimode optical fiber to possess, at a wavelength of 850 nanometers, a radial offset bandwidth of at least 6000 MHz·km for all radial offsets between 0 and about 70 percent of the radius of the optical fiber's core.
摘要翻译：对渐变折射率多模光纤进行分类的方法包括在单个波长下进行一系列单独的测量，并且使用这些测量来表征多模光纤的实际折射率分布与相应的标称折射率分布的偏离。与多模式色散或EMB测量相结合的测量可用于预测光纤在测量波长以外的波长处的近似透射特性。理想的是，渐变折射率多模光纤在850纳米的波长下具有至少6000MHz·km的径向偏移带宽，用于光纤芯的半径的0和约70％之间的所有径向偏移。
