  • a type of coaxial cable used to connect nodes on an Ethernet network. The10 refers to the transfer rate used on standard Ethernet, 10 megabits per second. The base means that the network uses baseband communication rather than broadband communications,and the 2 stands for the maximumlength of cable segment, 185 meters (almost 200). This type of cable is also called “thin”Ethernet, because it is a smaller diameter cablethan the 10base5 cables.

  • Telecommunications is one of the fastest growing business sectors of modern information technologies. A couple of decades ago, to have a basic understanding of telecommunications, it was enough to know how the telephone network operated. Today, the field of telecommunications encompasses a vast variety of modern technologies and services. Some services, such as the fixed telephone service in developed countries, have become mature, and some have been exploding (e.g., cellular mobile communications and the Internet).

  • The growing interest in the application of artificial intelligence (AI) techniques to power system engineering has introduced the potentials of using this state-of-the-art technology. AI techniques, unlike strict mathematical methods, have the apparent ability to adapt to nonlinearities and discontinuities commonly found in power systems. The best-known algorithms in this class include evolution programming, genetic algorithms, simulated annealing, tabu search, and neural networks. In the last three decades many papers on these applications have been published.

  • Telecommunication networks are not static. In order to support evolving service offerings, they must evolve in size, shape and complexity. Initial network design should consider the need for expansion and growth. Proper design plays a critical role in determining whether a network is an effective revenue generator, or whether it loses profitability through excess labour costs and missed service opportunities. FlexDSX™ cross-connect products provide the necessary network flexibility.
