摘要：An optical fiber () includes: a core (); a first cladding () surrounding the core ()

and having a lower refractive index than the core (); and a second cladding () surroundingthe first cladding () and having a lower refractive index than the first cladding (). The firstcladding () is doped with light attenuating dopant so that a concentration of the lightattenuating dopant in the first cladding () increases from an inner surface of the firstcladding () toward an outer surface of the first cladding ().
