Abstract

According to some embodiments a single mode fiber includes: a germania doped central core region having outer radius ri and relative refractive index D i; and a cladding region comprising (i) a first inner cladding region having an outer radius r2 > 6 microns and relative refractive index Δ2 and 0.3<ri/r2<0.85; and (ii) a second inner cladding region having an outer radius r3>9 microns and comprising a minimum relative refractive index Δ3 , wherein said second inner cladding region has at least one region with a relative refractive index delta that becomes more negative with increasing radius; and (iii) an outer cladding region surrounding the inner cladding region and comprising relative refractive index Δ4 , wherein Δ1 > Δ2 > Δ3 , Δ3 < Δ4 .
