Abstract

With the development of the high performance optical fiber amplifiers, long haul transmission systems such as submarine cable sytems have moved to non-regenerating one using the optical amplifiers. In the non-regenerating systems, accumulation of signal distortion caused by the fiber nonlinearity is one of the major problems, because optical signals travel thousands of kilometers without reshaping. Transmission fibers used in these systems should be redesigned after consideration on the nonlinear sensitivity. In this paper, we report design of dispersion shifted fibers with reduced optical nonlinearity.
