Cables huh? What do I need
rounded cables for? Have you ever heard that conversation?
Well, unless your a hardcore performance junky you may not need the
benefit of rounded cables. If you would like a Ferrari however,
these cables will assist you in eking out every last bit of performance
from a high level system. |
Three Facts
1. The
cables are rounded - Rounded cables are more aerodynamic to assist in airflow
efficiency.
Round and Round We Go!
Rounded cables are more
aerodynamic. For the most part, computer users have tons of flat ribbon cable
strewn from here to there to connect hard drives, floppy drives, and CDROMs.
Most of the time, these cables are broadside to the airflow acting like a
sail. Unless this cable is stuck to the side of the case and out of the
airflow, it is very inefficient. A rounded cable, with a lesser cross
section, takes up less space broadside and the air passes more effectively
over it and also does not create as much
turbulence, allowing more air to move downstream.
2. The cables use twisted pairs - Twisted pair cabling is the most efficient
design in high Electro-Magnetic Interference
environments
3. The cables are shielded - Shielding gives cables added protection against EMI
History of the Twistory
Unshielded Twisted Pair
(UTP) has been designed for use in voice applications and local area networks.
Because of the relatively low cost this cable is widely used and is available
in several different performance categories (Categories 3, 4, 5 and 6). Over
99% of our copper installations are UTP versus Shielded Twisted Pair
(STP), which is rarely used.
Electromagnetic interference is present in all
types of cabling to some degree. There are two basic types of electromagnetic
interference (EMI) to worry about - electromagnetic emissions and
electromagnetic immunity. Emissions refer to energy that is radiated by the
cable, and immunity is the ability of the cable to reject outside signals. The
latter should be referenced in reading this article. Failure to properly
manage EMI can have an adverse effect on the integrity of the signal being
transmitted.
In an unshielded cable, careful design of the
cable and the associated electronic equipment results in a "balance"
of the currents in the two conductors of a pair. That is, the currents in the
two conductors are equal in magnitude but flowing in opposite directions.
Proper installation and termination of the cable is also critical to
maintaining this balance.
In a balanced system, there is very little
radiation of EMI since the external field from one conductor is effectively
canceled by the external field from the other conductor of the pair.
Generally, the more twists per foot of cable, the better the cable is
electrically balanced. Category 5 cable has more twists per foot than Category
3 or 4 cables and, therefore, offers better protection from EMI problems.

In conclusion, these cables are
beautifully designed and I would like to say much higher performance.. but that
would just not be true. You will achieve a minimal performance gain. These
cables just scream speed and style though. They really finish off a nice
case internally giving a very clean look and feel. These are the finest cables I
have ever seen and you will not need another set until the technology is
altered.. not anytime soon...
