    Engine generator sets used as alternate sources of power (i.e., emergency or standby power) must be properly grounded. Also, the associated transfer switches must be properly selected. The author describes how this is necessary to protect personnel and equipment, and to provide reliable ground-fault sensing and continuous power to electrical loads View full abstract»

    The forces for high speed, high capacity data services are driving the next generation network architecture toward a packet network. These next generation networks are basically of two types: wired networks and wireless networks. Changes in network services, technology and regulation are creating a golden era of network innovation. Much is certain in this evolution. For instance, the networks will have a shared, packet-based, optical-core network using dense wavelength division multiplexing (DWDM) optical transport with optical add/drop and multiplexing. Wireless communications is expected to be a major driver for growth in the telecommunications industry over the next decade. It will become a cornerstone of the information society. Future networks (both wireless and wireline) of the type described here will pave the way for an environment in which information will be made more portable, personal and affordable. They will achieve the ultimate goal of communications-communications from anywhere to anywhere-clear as a bell View full abstract»

  • Photons vs. electrons [all optical network]

    The article addressed a number of questions pertinent to the development of all optical networks (AON). Was one possible? And what optical technology developments were needed to get there? Today, most wavelength division multiplexing (WDM) optical networks deployed still have one main network element at intermediate nodes with some electronic components. One primary component is the optical crossconnect (OXC), or optical switch. It does an optical-electrical-optical (OEO) conversion at some point to route the lightpaths to their next hop or destination because routing and switching technology is still based on electronics. This OEO conversion is one of the controversies that experts in this area deal with these days. Some say an AON is not quite there yet due to some technical issue such as lack of wavelength conversion, lack of signal regeneration at intermediate nodes and complex network management. Others say eliminating the electronic components in these network elements will solve some overall performance concerns such as bit-rate dependency and limited speed scalability. Also, there are others who propose a "semi-optical" network, eliminating a big part of the electronics but not entirely replacing them View full abstract»
