Copper Data Cables
The development of communications cable technology is rapidly changing and the use of high speed networks is growing exponentially. CABLOFIL has become accepted as the ideal support for copper communication cables (coaxial cables and twisted pairs).
New Standards for New Performance
The category characterizes the performance level of a single component, such as a cable, connector or even a lead. For example, a cable will be stamped "Cat. 6" if it passes the tests required for Category 6 approval.
The class characterizes the performance level of a combination involving more than one component (e.g. cable + connector). As such, the class defines the performance level of an installation rather than providing information on a component.
When compiling specifications, it is best to specify the desired application class as well as the category of the components to be installed.
Low cost and easy to manipulate, screened coaxial cables are used in data, industrial and instrumentation applications to transmit fast digital signals at low level.
This type of cable is most commonly used for telephone and data applications in local area networks. The pairs, two intertwined copper wires, are insulated from each other by plastic and enclosed in a sheath.
U/UTP Unshielded Twisted Pair
Unshielded twisted pairs in an unscreened sheath. The most widely used around the world and also the cheapest.
F/UTP Foiled Twisted Pair
Twisted pairs in a screened sheath. Mostly used in France.
S/FTP or S-STP Screened Shielded Twisted Pair
Screened twisted pairs in a screened sheath. Mainly used in Germany.
The screening of FTP and STP cables will only be effective against electromagnetic interference if both ends are connected to earth.
The two major considerations for the network infrastructures are the reliability and durability of the installation. In order to measure the positive contribution made by CABLOFIL, even when overloaded with cables, a series of independent tests were carried out.
The aim is to develop a detailed understanding of the short-term or long-term benefits of using CABLOFIL, as opposed to conventional flat-bottomed supports, for Cat. 5e and Cat. 6 cables. CABLOFIL had its cable trays tested by Intertek Testing Services, a division of ETL, the world's leading provider of testing, inspection and certification services.
For the two tests described below, parameters relating to cable characteristics (NEXT, FEXT, Attenuation Return Loss, etc.) are measured in different configurations. The main parameter selected for comparison purposes is Return Loss. The aim is to define a cable's impedance regularity. Each irregularity causes the signal to return to its source.
Test for reliability under load
90 meters of Cat. 5e and Cat. 6 cables are tested with no load, before being subjected to mechanical stress equivalent to the weight of 40 cables stacked together. Measuring and comparing the Return Loss for each configuration determines the effect of the support.
The tests show that, for a Category 5e or Category 6 cable subjected to a load of 40 cables, there is not significant difference in behavior between CABLOFIL cable tray and a support with a flat base.
Test for durability under load
In order to establish how data cable installations change over time, the equipment is subjected to a simulated 15-year aging process based on extremely stringent military standards and the same tests are performed. The cables and supports undergo 200 cycles over large temperature variations (-40F to 185F) over a period of 2 weeks.
The cable supported by CABLOFIL, an open and ventilated system, performs better than a closed system with a flat bottom which does not allow heat to dissipate.
