| Abstract | ||
| In this paper, comparative study of three dispersion compensation fiber models, namely, pre, post and symmetrical involving ideal dispersion compensation fiber Bragg grating for three different modulation schemes in 40 Gb/s single channel optical fiber transmission system are performance evaluated. Three modulation schemes, different namely, duo-binary coding, modified duo-binary and carrier suppressed return to zero are simulated and analyzed in terms of Q-factor and bit error rate for each set up by range of CW laser power. The simulation of optical system based on optisystem-10.The result report that the symmetrical with ideal FBG at duo-binary coding depicts good performance for increasing the input power from-5 dBm to 10 dBm. It is clear that best Q value obtained is 28.24 dB for BER of 5.9 ×10-176 at input power of 5 dBm using symmetrical compensation cascaded with ideal FBG for duo-binary modulation scheme. | ||
