Abstract
According to at least one embodiment a graded index multimode fiber (10) comprises: (i) a silica based core (20) co-doped with Ge02 and 1 to 12 mole % P208 ; the core (20) having a dual alpha, a i and a 2, where 1.8 ≤ αi ≤ 2.4 and 1.9 < α2 ≤ 2.4 at the wavelength (λ) range between 840 and 1100 nm; and (ii) a silica based cladding region (200) surrounding the core, wherein the o fiber has a numerical aperture NA and 0.185 < NA < 0.25 (more preferably 0.185 ≤ NA ≤ 0.23). Preferably, the silica based cladding region (200) surrounding the core (20) has refractive index lower than that of pure silica.
