“…When considering the suitability of UWB systems, we must consider the constraints placed on optical systems in different parts of the network. Transoceanic communication cables [76] have often been at the forefront of adopting fiber technologies, including EDFA [77]. Because these systems deploy both amplifiers and fiber at the same time, the issue of legacy fiber losses is less problematic.…”

Ultrawideband Systems and Networks: Beyond C + L-Band

In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most cost-efficient and thus the main driver for capacity increase for decades. As a result, the development of optical transport systems has been focused on the C-and L-bands, where silica optical fiber exhibits the lowest attenuation, and erbium-doped fiber amplifiers provide an efficient solution to compensate for the optical loss. With a gradual maturity in the SE growth, however, the extension of the optical bandwidth beyond the C + L-band is expected to play a significant role in future capacity upgrades of optical networks and, thus, attract increasing research interests. In this article, we discuss the merits and challenges of ultrawideband optical transport systems and networks beyond conventional bands. KEYWORDS | Optical communication; optical network and switching; optical transceiver (TRx); Raman amplification; ultrawideband (UWB) transmission; wavelength conversion; wavelength-division multiplexing (WDM).

“…TAT 8, the first optical transatlantic telephone cable laid in 1986, had a capacity of 280 Mbit/s over two pairs of single mode fibers operating at 1.3 micron. In 1995-1996 the TAT 12-13 cable network was laid [19]. It consists of two transatlantic cables, one between the United States and England, the other from the United States to France plus two interconnections, one between France and England at the East end and the other between New York and Rhode Island at the West end.…”

“…To this end, several long haul, large-capacity fibre optic networks were planned to begin operation by early 1997. These include the 27,000km Transatlantic cable linking the USA and Europe with a capacity of 10 Gigabits per second; the trans-Pacific cable network, linking the USA and Japan with a capacity of 10 Gigabits per second; the 11,000km Asia-Pacific cable network, with a capacity of 5 Gigabits per second; and the 27,000km FLAG network connecting Europe and Asia, with a capacity of 10 Gigabits per second (Trischitta et al, 1996;Welsh et al, 1996;Barnett et al, 1996;Gunderson, 1996;Marra et al, 1996). The 40,000km Africa-ONE cable network, which is planned to connect 40 coastal and landlocked African countries, with each country obtaining 30,000 basic circuits, is planned to be ready by 1999 (Sandler, 1997).…”

By 2016, Botswana aspires to triple its 1994 per capita income and to completely diversify its economic base. The Southern African Development Community (SADC) objectives, as spelt out in the SADC Policy document, emphasise the attainment of enhanced development and economic growth, poverty alleviation, and support of the socially disadvantaged through regional integration. Since telecommunications have long been recognised as the engine for economic growth, the aspirations of SADC and Botswana are consistent with the SADC Protocol on Transport, Communications, and Metrology, which aims at developing a reliable, efficient, vibrant, consumer‐driven telecommunications sector. We examine the focus of the World Bank and the International Telecommunications Union, in global telecommunications development. We then discuss the efforts of Botswana and other SADC states in ensuring that they take advantage of the private sector finances to build reliable, sophisticated public telecommunications networks for entry into the Global Information Infrastructure (GII).
