Shielded and Unshielded Ethernet Cables: Making the Best Buy

Shielded and Unshielded Ethernet Cables Making
the Best Buy
Digital Signal Processing is the process of
transmission and production of data that takes
place without any interference. This process asks
for an Ethernet Cable. Most of the wired networks
of today including routers, PCs and switches use
Ethernet cables for the smooth transmission of
data. These Ethernet Cables are of two types
Shielded and Unshielded. They are also known as
STP (Shielded Twisted Pair) and UTP (Unshielded
Twisted Pair). The question that arises next is -
which one out of the two you should buy? To find
this out, make sure you know about the
environment you need Ethernet cables for. One of
the major reasons behind networks slowing down is
- voltage interference. Hence, you must make sure
that the electrical line intersects with low
voltage communication cable at 90 degrees. Given
below are some other factors you should consider
before buying shielded or unshielded Ethernet
cables. ? Alien CrossTalk The antenna of
Ethernet cables are like the cross-section.
During the times of high frequency signal
transmission, Alien CrossTalk (AXT) creates major
hindrances. To avoid this, you need to know what
is causing interference - the near end crosstalk
or the foreign interference. Once you find that
out, you can decide which cable to use for
installation. In order to curb the effects of
ATX, one should choose a shielded cable. Even if
the shields are electrically bonded, robust
grounding is must. Natural grounding can be
enabled by appropriate couplers and jacks.

? Choosing cables for places with heavy
machinery When it comes to choosing the Ethernet
cable for healthcare facilities or places where
heavy machinery is used, Cat 6a STP should be
preferred over Cat 6a UTP. Cat 6a STP comes with
a shield that keeps the radio frequency
interference away from the twisted pair. ?
Installation time for UTP and STP There is no
need to discriminate between the two shielded
cables on the basis of installation time
required. STPs latest version comes with easy to
set up die cast jacks and thus it doesnt ask for
prolonged steps of installation. However, you
must keep in mind that you will take some time to
detach the general shield from the cable. If you
choose UTP, you will take time to test the AXT
process. Installing STP, on the other hand, wont
take long. ? Cost Consideration A shielded
Ethernet cable would definitely cost you more
than UTP. But considering factors like less
testing time and superior quality performance, it
may be totally worth buying it. After all, time
is money. ? Keep the future upgrades in mind The
field of communication technology is always
evolving. Hence, you must make sure that you
dont need to upgrade the cables time and again.
Make sure you utilize transmission cables that
surpass the current transmission rate of 10 GB/s.
Keeping these factors in mind, STP is always a
better choice.

? Bonding process for STP It is believed that
installing shielded cables asks for a more robust
grounding and bonding process. This might be a
myth. STP, just like other cables requires the
same kind of grounding provided its shield is
attached to the patch panel. The quality of
signal that is received at the end of
transmission is dependent on the quality of data
that is fed to it. So now you know the
difference between Shielded and Unshielded
cables. While buying Ethernet Cables, keep the
above points in mind and you will never have
network hindrances. You can also ask the
installation experts to guide you in case of any
confusion.
