Abstract
Data representation represents converting bits into signal forms. These signals match the conditions of the transmission, such as DC levels and channel capacity for optical fiber system with linear and nonlinear effects; it is important to check the suitable data representation for a certain type of modulation. In this paper, a comparison has been made among several kinds of representations like Manchester, alternate mark inversion (AMI), ordinary non-return to zero (NRZ), chirped NRZ and Duobinary (DB) for single-channel optical fiber with direct transmission at 10 Gbps of 350 km (without DCF compensation) length. The results are taken in terms of power versus quality factor and optical signal spectrums in both sides. They showed that Manchester coding has a 12 order difference in signal power at the end of the fiber, and AMI coding has the farther threshold power point of 9dBm with a quality factor of 14 by using Optisystem version 13.
