Abstract :
Due to fiber nonlinear effects such as self-phase modulation (SPM) and cross-phase modulation (XPM), the transmission signal is distorted. Thus the low nonlinear dispersion-shifted fiber (DSF) is required to achieve high-bit-rate transmission using the 1.55-μm band. The studies to fabricate the large effective area (Aeff) fiber were activity done, because nonlinearity is expressed as n2/Aeff . To obtain large Aeff, large MFD is required. However, the MFD is limited because of bending loss. Lowering n2 is also considered to be effective. In the paper a low nonlinear dual-shape core (DSC) type DSF produced by VAD was investigated, by expanding MFD and reducing n2
