CRZ ?An ideal choice for low BER in XG-PON Hybrid (DWDM-PON/ FSO) Network at 80 (8X10) Gb/s over 60 km fiber length in upstream transmission

Abstract

In this paper, we have dealt with possibilities of exploring the right candidate from amongst the various types of modulation formats (RZ, NRZ & CSRZ), in XG-PON Hybrid (DWDM-PON/ FSO) Network. The purpose was to achieve low BER at high bit rates of 80(8X10) Gb/s over link distance of 60 km fiber length in upstream transmission from amongst the individual modulation formats. These modulation formats were evaluated with perspective to permissible limits of parameters Q-factor and BER in RSOA based Hybrid optical access networks.
