A dispersion compensating (DC) fiber preferably including a central segment having a relative refractive index, a depressed moat segment, an intermediate segment, an annular ring segment and a cladding layer. The relative refractive index profile of the DC fiber is selected to provide negative dispersion, negative dispersion slope, a kappa value of less than or equal to about 100, and MPI of less than -40 dB at 1550 nm. The DC fiber preferably has a pin array bend loss of less than or equal to about 30 dB at a wavelength of about 1550 nm.
