Abstract
With the rapid increasing bandwidth demand mainly driven by the development of advanced broadband multimedia application, such as video-on-demand (VoD), interactive high-definition digital television (HDTV) and video conference, new access network solutions that provide high capacity are highly needed to satisfy these emerging services. In a largely populated and technologically exposed institution such the University of Port Harcourt, this demand is truly great. The Passive Optical Network (PON), which utilizes the Fibre Optic Technology, is a suitable solution to this problem. Hence this is geared towards the design and simulation of a Passive Optical Network for the University’s campus district. This Campus based Local Area Network consists of the Various Faculty buildings, the Senate building which is the central administrative building, and was centralized at the Information and Communication Technology Center (ICTC), which served as the Central Office of the network. The Wavelength Division Multiplexing (WDM) technique was utilized because of its dedicated bandwidth for each subscriber and more flexible bandwidth management. The validation was carried out on a virtual computation environment called OptiSystem©.
Highlights
In the world today, it is clearly seen that there is an everincreasing growth in Internet traffic and data demand, and this trend is expected to continue
We look at designing a Passive Optical Network that would serve as the framework of the Local Area Network of the Abuja Campus of the University of Port Harcourt
The system was analysed to verify performance using the Eye Diagram and the values obtained from the BER (Bit Error Rate) anaylisers attached to every receiver unit
Summary
It is clearly seen that there is an everincreasing growth in Internet traffic and data demand, and this trend is expected to continue. Many of our activities these days are mostly online and involve a frequent use of many bandwidth demanding applications According to one such expert in [2], new or improved access network solutions that provide high capacity will be needed to satisfy the emerging network services and multimedia, due to the rapidly increasing bandwidth demand. This need is mainly driven by the development of advanced multimedia application, such as video-on-demand (VoD), interactive high-definition digital television (HDTV) and video conference. They are not considered as future-proof solutions, because these copper wire-based infrastructures have been approaching their own fundamental speed limitation, and wireless communication are reaching their bandwidth capacity limit
