TAILIEUCHUNG - Electrical Characteristics

The AirES product range of cables are a true innovation in structured cabling. In most evolutionary processes the gain in one attribute often sacrifices another. With the AirES evolution all attributes, both physical and electrical, are improved to provide a "Win Win" situation for both the installer and customer. | TrueNet AirES Technology Electrical Characteristics of the Evolution The AirES product range of cables are a true innovation in structured cabling. In most evolutionary processes the gain in one attribute often sacrifices another. With the AirES evolution all attributes both physical and electrical are improved to provide a Win Win situation for both the installer and customer. This white paper will focus on the electrical attribute advantages of AirES. Herein we will discuss the revolutionary development of the technology and the by-product effects on any and all electrical parameters. A full glossary of terms is included for further understanding. TrueNet AirES Technology Electrical Characteristics of the Evolution Background To fully understand the benefits of the TrueNet AirES solution one must first understand the fundamentals of cabling and the hurdles overcome by this product. Good Dielectric Constant is key in producing high quality data communications cable. The lower the Dielectric Constant of the insulation material the better the resistance to breakdown when an electrical field is applied. Air with a Dielectric Constant of is the best of all insulators and is the basis by which others are measured. ADC has understood this and has been using air as an insulator in our connectivity products for many years. Below is an example of different materials and their Dielectric Constants. Water Glass and Air were added to the list to give a better understanding as to what constitutes a good Dielectric Constant. It may be relevant to note the Dielectric Constant of Glass is higher than FEP insulation. This results in fiber optic cables having a lower Nominal Velocity of Propagation NVP than UTP copper cables. O PVC Air The NVP is the speed a signal propagates through a cable expressed as a percentage of the speed of light in a vacuum 300 m sec and given the value of 1. The NVP of a data communications cable can be directly calculated from the dielectric .
