High SBS threshold optical fiber with aluminum dopant
An optical fiber comprising a core having a refractive index profile and a centerline; and a cladding layer surrounding and directly adjacent the core; wherein core includes updoping material and is doped with Aluminum in at least one region of the core, such that either: (a) the average longitudinal acoustic wave velocity within the core is within 0.05% of the longitudinal acoustic wave velocity within the cladding; or (b) the longitudinal acoustic wave velocity in the core changes by at least 0.2%.
