Abstract: Disclosed is an optical fiber which includes a core including silica with a core diameter and having at least two dopants, a maximum relative refractive index delta of at least 0.7% and an alpha value in the range of 1.9-2.2. The core has a refractive index profile configured to transmit light in a multimode propagation at a first wavelength λ 1 in the range of 800-1100 nm and to propagate light in a LPO1 mode at a second wavelength λ 2 . The second wavelength λ 2 is greater than 1200 nm. The optical fiber is structured to have a LPO1 mode field diameter in the range of 8.5-12.5 μm at 1310 nm.
