Aims: This paper presents a Gigabit Passive Optical Networks (GPON) model which includes a power budget analysis, availability analysis and signal performance analysis of the system. Study Design: A Gigabit Passive Optical Networks (GPON) model. Place and Duration of Study: Department of Electronics and Communication Engineering, Khulna University, Khulna-9208, Bangladesh, between June 2017 and February 2018. Methodology: The system performance is presented through various parameters such as Q factor, eye diagram.

Results: The proposed models have the nominal downstream bit rate 2Gbit/s with required bandwidth.

Conclusion: The model has very efficient packaging of user traffic, with frame segmentation to allow for higher QoS for delay-sensitive traffic such as voice and video communications.
