The ITU-T G.984 is Gigabit-capable Passive Optical Networks (GPON) standard. In this paper, 2.5 Gb/s GPON link is presented. The quality or performance of a digital communication system is specified by its BER or Q value with respect to other parameters such as receiver sensitivity . The system performance is presented through various parameters such as Q factor, eye diagram. The proposed models have the nominal bit rate 2.5 Gbit/s with required bandwidth. It implemented using Opti-System 7.0.
