Reliable ICT services reduce the influence of geographical obstacles in bringing people together, and improve social-economic development in any country. However in Tanzania, ICT services are limited because Tanzania doesn't have its own ICT backbone infrastructure. In order to close the digital divide with other countries and enhance sustainable socio-economic development and accelerate poverty reduction in the country, Tanzania must construct a high capacity internationally connected terrestrial ICT backbone. This can be achieved using optical DWDM network technology, which can provide virtually unlimited bandwidth with minimum costs, for all ranges of ICT services such as Internet, voice, videos and other multimedia interactions. This article explores the performance of a DWDM system utilizing erbium-doped fiber amplifiers (EDFA) with a dispersion compensating fiber (DCF) in a standard single mode fiber (SSMF) for deployment as the Tanzanian ICT backbone. Performance assessments at data rates of 2.5 Gb/s and 10 Gb/s per wavelength channel take into consideration the presence of each optical component. The simulation results show that a data transmission rate of 2.5 Gb/s can be successfully transmitted with an external transmitter modulator over a greater distance than 10 Gb/s with minimum system impairments. Operating at the lower data rate delivers a cost effective infrastructure with good system performance for the required ICT services. A forty-channel DWDM system will provide a bandwidth of 100 Gb/s. © EuroJournals Publishing, Inc. 2009.
