Abstract
A multicore optical fiber comprises a common cladding and a plurality of core portions disposed in the common cladding. Each of the core portions includes a central axis, a core region extending from the central axis to a radius r, the core region comprising a relative refractive index Δ, an inner cladding region extending from the radius rto a radius r, the inner cladding region comprising a relative refractive index Δ, and a depressed cladding extending from the radius rto a radius r, the depressed cladding region comprising a relative refractive index Δand a minimum relative refractive index Δ. The relative refractive indexes may satisfy Δ>Δ>Δ. The mode field diameter of each core portion may greater than or equal to 8.2 μm and less than or equal to 9.5 μm.
