Title
(EN) Low bend loss optical fiber with deep depressed ring
(ZH) 具有深抑制环的低弯曲损耗光纤
Abstract
(EN)
Optical waveguide fiber that is bend resistant and single moded at 1260 nm and at higher wavelengths. The optical fiber includes a core and cladding, the cladding having an annular inner region, an annular ring region, and an annular outer region. The annular ring region has a low relative refractive index. The fiber has a zero dispersion falling between 1300 and 1324 nm, a mode field diameter at 1310 nm of between 8.20 and 9.50 mu m, and a 10 nm diameter mandrel bend loss of less than 1.0 dB/turn.
