Planning, Design and Simulation of a Network Access Based on FTTH-EPON for Hadhramout University

Abstract

Abstract In our country copper infrastructure from Central Office (CO) to the end user is responsible for delivering poor Broadband services with loss reach 86% of the overall capacity speed. Not to mention the high prices and the impact of this inferior service to the education and economy of the country. Therefore, This paper presents a procedural proposal solution for planning, design and simulation of Ethernet Passive Optical Network (EPON) performance through Fiber-to-the-Home (FTTH) technology applied on College Of Engineering and Petroleum campus at Hadhramout University as it the best way to overcome all the problems related with copper. Since the fiber terminates at the campus, we termed the network, Fiber To The Campus (FTTCampus). FTTCampus planning the location network was developed through Google Earth and AUTOCAD software which was implemented to map out the college location areas. The proposed optical network system design has been simulated based on EPON IEEE 802.3ah standards through Optisystem software program. Simulation network components such as optical transmitters, Optical network terminals (ONTs), and optical splitters among others were allocated at different coverage areas and various network links were connected among these coverage areas. A downstream network of EPON has been simulated using Continuous Wave Laser (CW Laser) and Directed-modulated Laser (DM Laser) as different optical. Validation was performed with consistent output performance indicators like quality factor, optical source power (dBm) and bit error rate (BER). This paper has a main objective in designing an affordable and feasible network and it is accomplished by utilizing EPON that merges the low-cost Ethernet technology and low-cost PON structure with the DM Laser as an optical source. This unique work revealed that, FTTCampus could be a reliable technology in an educational academic institution, if implemented.
