Telecom applications

Whatever the nonlinear process involved, the metal/dielectric nanocomposites have been often inquired into for their optical limiting (OL) properties [120, 123, 124, 140-150], owing to the important stake that such a functionality represents for civil and military applications in human eye or detector protection. Indeed, as for telecom applications, metal nanoparticles present the advantages of both intense and fast nonlinear response.

This switching power supply (Figure 1.35) was designed for high-reliability telecom applications where there was a requirement for a light-weight. 

In 2011, General Electric in the USA began producing nickel chloride batteries under the name Durathon. They are intended for grid-connected renewable energy storage, telecoms applications and, more generally, backup power supply and industrial transport needs. 

Reliability can be designed in by PWB designers, as they know which component packages are used, what the CTE requirements of these packages are, and what the life-expectancy requirements of the electronic equipment are. The ability to tailor in-plane CTE has made non-woven aramid-reinforced PWBs one of the most favorable material options for avionics, satellites, and telecom applications where long life expectancy and high reliability are needed.

The conductivity of a surface varies with the long-term pollution exposure in the operating atmosphere and its average humidity. The previously mentioned creepage spacings change for different applications, such as industrial, telecom, etc. The designer must refer to the appropriate specification. 

In Table 9 the recent statistics of ATES utilisations in Sweden are presented. As can be seen the technology is so far preferably used for commercial and institutional buildings with small or medium sized applications. Large-scale plants are applied for some district heating and cooling systems while the industry sector only has a couple of systems applied for manufacturing industries. The rest represents cooling in the telecom sector. 

An application already in the market is the temperature control utilizing PCM for transportation of pharmaceutical goods or other temperature sensitive goods. Also in the market is the utilization of PCM for cooling or heating of the human body, since it has been demonstrated both for personal comfort and for medical therapy. Passive cooling of buildings and of telecom cabinets are examples of widespread applications.
