Evaluation of Advanced Modulation Formats using Triple-Play Services in GPON Based FTTH

In this paper, an evaluation is performed of 2.5Gbps bi directional GPON based Fiber-To-The-Home (FTTH) link using advanced modulation formats. Gigabit Passive Optical Network (GPON) is a promising solution for increasing bandwidth requirements of customers which supports triple play services and is being considered as a solution for mobile back haul network. It also enables the delivery of cloud services with a high interconnection speed. The performance of the proposed system was studied when a single wavelength and two wavelengths were used for triple-play services with different modulation schemes. This paper is aimed to provide a comparison of the performance of different modulation formats for GPON based simulation of an actual architecture considering Q factor, BER, optical power and OSNR. The outcome shows that better results were observed for RZ DQPSK.
