发明名称 LOW BEND LOSS OPTICAL FIBER
摘要 <p>According to some embodiments a single mode fiber includes: a germania doped central core region having outer radius r1 and relative refractive index Delta1; and a cladding region comprising (i) a first inner cladding region having an outer radius r2 > 6 microns and relative refractive index Delta2 and 0.3<=r1 /r2 <=0.85; and (ii) a second inner cladding region having an outer radius r3 > 9 microns and comprising a minimum relative refractive index Delta3, 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 Delta4, wherein Delta1 > Delta2 > Delta3, Delta3 < Delta4.</p>
