In this paper, we first measure fiber nonlinear Kerr coefficient of a two-mode fiber (TMF) by characterizing the four-wave mixing (FWM) components. Based on the measured nonlinear coefficient, we present an analysis of the link capacity for a two-mode fiber. It is shown that despite strong spatial overlapping of the three modes, the overall capacity approaches three times of that of a single-mode fiber.
