摘要:
An optical fiber comprising: (i) a glass core (20) extending from a centerline and including a central core region (22) with an alpha value of less than 2, a first annular core region (24) surrounding the central core region (22), and a second annular core region (26) surrounding the first annular core region (24), wherein the second annular core region (26) has a higher maximum relative refractive index percent Δ26MAX than that maximum relative refractive index percent Δ24MAX of the first annular core region (24); and (ii) a glass cladding (30) surrounding and in contact with the core (20), the cladding comprising: (a) a first annular cladding region (32) extending from a radius R32 to a radius R34, (b) a second annular cladding region (34) extending from the radius R34 to a radius R36, (c) a third annular cladding region (36) surrounding the second annular region (34) and extending from the radius R34 to an outermost glass radius R36; wherein the core (20) comprises a maximum relative refractive index percent, ΔCMAX; wherein said first annular cladding region (32) comprises relative refractive index percent Δ32(r) % the second annular cladding region (34) comprises a minimum relative refractive index percent, Δ34 MIFN, wherein ΔCMAX>Δ32MAX>Δ34MIN, and Δ34MIN
