The elements of fibre cable management

As service providers upgrade their networks to transport high-bandwidth broadband services, an increase in fibre usage is essential to meet both bandwidth and cost requirements. But just deploying this additional fibre is not enough – a successful, well- built network must also be based on a strong fibre cable management system. Proper fibre management has […]

A competitor for graphene

  Graphene, the only one atom thick carbon network, achieved overnight fame with the 2010 Nobel Prize. But now comes competition: Chemists at the Technical University of Munich (TUM) have now developed a semiconducting material in which individual phosphorus atoms are replaced by arsenic. Ever since its founding in 1868, TUM has been at the […]

Battery-charging considerations for high-power portable devices

Cell phones are a good example of how functionality and performance have both increased significantly in portable devices over the last few decades. They have become more complex and can do many basic tasks as well as any computer. The extra functionality that has transitioned the smartphone from a phone-call-only device to a multi-purpose portable […]

Green power: Energy storage remains the weakest link

  Of all the new technologies being developed across the globe, batteries – or rather, energy storage – remains the weakest link in any system. Researchers are continually improving the efficacy of solar cells and wind generators but the question of how to store it for when it is needed most seems to elude the […]

Using soft ferrites for interference suppression

  In the field of electromagnetic compatibility several trends point to a growing necessity of EMC engineering. These trends, directed to functional upgrading or reducing cost, inevitably also contribute to an increasing level of electromagnetic interference (EMI) emissions. The article covers general principles of EMC and EMC regulations, material specifications and EMI-suppression product lines. Applications […]
