Abstract: A modal-conditioning, single-mode fiber generally includes a core portion and a cladding portion. The core portion includes a core and an inner cladding. The core comprises an outer radius r1 and a maximum relative refractive index Δ1max. The inner cladding comprises an outer radius r2 and a relative refractive index Δ2. The cladding portion surrounds the core portion and includes a low-index trench surrounding the inner cladding. The low-index trench includes an outer radius r3 and a minimum relative refractive index Δ3min. The radius r2 of the inner cladding may be greater than 12 μm and Δ1max>Δ2>Δ3min. The fiber comprises a mode field diameter MFD greater than or equal to 12 μm and less than or equal to 16 μm at a wavelength of 1310 nm and a 30 mm diameter bend loss of less than or equal to 0.5 dB/turn at 1310 nm.
