Abstract
Abstract This work outlines 80-channel wavelength multiplexing that has been developed with optimum length-based erbium-doped fiber amplifier (EDFA) with dispersion-compensated fiber. This paper has presented different fiber mediums with different effective areas such as single mode fiber (SMF), highly nonlinear fiber (HNLF), highly nonlinear dispersion-flattened fiber (HNL-DFF), nonreturn to zero dispersion-shifted fiber (NRZDSF) and a two types of large effective area fiber (LEAF Step core and LEAF Ring core) with dispersion-compensated fiber and EDFA amplification. Optimum fiber length can be obtained using minimum and maximum bit error rates with channels number and bit rate variations.
