Impact of the HFC migration to FTTH on the efficiency and reliability of the internet provider services business (A case Study)

Abstract

This paper presents the impact on the efficiency, reliability, and quality of the Internet provider services due to the migration of the Hybrid Fiber Coaxial (HFC) to the Fiber To The Home (FTTH) infrastructure. The implementation of the emerging technology on communication caused an increase in the internet service provider business competition and it makes the company that engaged in this field will compete to provide the best service to the customers as especially on the efficiency and reliability of the services to whom using the FTTH. The comparison and analysis of the impact of the HFC stand-alone to the FTTH technology migration process on both of the customers sides as well as the Network Availability and the percentage of uptime (connection to the ISP’s) of customer devices are provided. In this case study, it is found that the infrastructure cost of the technology HFC system is cheaper about 53.93 percent than the technology FTTH system. However, from a reliability perspective, FTTH is much better than HFC. It is found that the impact of the migration from HFC to FTTH shows the yearly Network Availability was 98.635 percent with a downtime of 2,819,473 minutes. And it provides an increase of Network Availability after construction (during commissioning or acceptance test). In addition, it was found that the correlation between uptime/downtime before migrating during employed the HFC technology, there were many problems caused by power supply problems and high losses of the coaxial cable. So if the coaxial cable is replaced by the fiber optic cable, will be there is an increase in the availability of the Network Availability during 2020 by 1.301 percent. Also by takeout the FDT on the FTTH, it is predicted that the cost reduction about 10 percent, faster implementation for the schedule and fewer cables maintain.
