用于模分多路复用的少模光纤
摘要：
披露一种适用于模分多路复用(MDM)光传输系统的少模光纤。该光纤具有渐变折射率纤芯，该渐变折射率纤芯具有在8μm至14μm范围内的半径R1、在1550nm的波长处大于或等于约2.3并小于约2.7的α值以及相对于包层从大约0.3%至大约0.6%的最大相对折射率Δ1MAX。光纤也具有大于约90μm2并小于约160μm2的有效面积。纤芯和包层在大于1500nm的波长处仅支持LP01和LP11模。包层具有最大相对折射率Δ4MAX，其中Δ1MAX>Δ4MAX，并且LP01和LP11模之间的差分群延迟在1550nm的波长处小于约0.5ns/km。
摘要（英）：

A few mode optical fiber suitable for use in a mode division multiplexing (MDM) optical transmission system is disclosed. The optical fiber has a graded-index core with a radius R1 in the range from 8 [mu]m to 14 [mu]m, an alpha value greater than or equal to about 2.3 and less than about 2.7 at a wavelength of 1550 nm, and a maximum relative refractive index Delta1MAX from about 0.3% to about 0.6% relative to the cladding. The optical fiber also has an effective area greater than about 90 [mu]m2 and less than about 160 [mu]m2. The core and cladding support only the LP01 and LP11 modes at wavelengths greater than 1500 nm. The cladding has a maximum relative refractive index Delta4MAX such that Delta1MAX>Delta4MAX, and the differential group delay between the LP01 and LP11 modes is less than about 0.5 ns/km at a wavelength of 1550 nm.
