Abstract
A disclosed multimode optical fiber comprises a core and a cladding surrounding the core. The core has an outer radius rin between 20 μm and 30 μm. The cladding includes a first outer cladding region having an outer radius rand a second outer cladding region having an outer radius rless than or equal to 45 μm. The second outer cladding region comprises silica-based glass doped with titania. The optical fiber further includes a primary coating with an outer radius rless than or equal to 80 μm, and a thickness (r−r) less than or equal to 30 μm. The optical fiber further includes a secondary coating with an outer radius rless than or equal to 100 μm. The secondary coating has a thickness (r−r) less than or equal to 30 μm, and a normalized puncture load greater than 3.6×10g/micron.
