Secrets of Mysterious Ethernet Cable
Revealed! The most important equipment used on
wired computer networks is an ethernet cable.
The use of Ethernet cable is for
connecting computers, routers, switches in a
local area network. It looks like a phone cable
but has more wires and is larger. These
cables are physically attached they need to
have certain peculiarities. The cables
physical characteristics alter or modify in
accordance of the requirements. The purpose
of the cables usability gave birth
to different categories. Different type of
network cables design creation is to ensure
its performance of certain tasks in a
particular situation. Therefore, which type
of ethernet cable suits the best - is a
common headache for us. Why do these cables
contain twisted pair of wires? Sometimes these
wires have a cover, sometimes they do not. Why so?

The cable designs vary in length, range,
intensity, and ability in transmitting
network signals. The available standard
ethernet cables in the market are the category 5
(CAT5), enhanced category 5 (CAT5E), category
6 (CAT6). The last standard cable
is the augmented category 6 (CAT6A). Let us
examine the differences closely. Specifications T
he higher you go in the category,
higher is the speed and frequency. The
stringent testing elements and added
isolation between the wires makes this possible.
CAT5 is a standard ethernet cable with the
maximum transmission speed up to 100MB/second and
a frequency of 100MHz. For Cat5E, the maximum
speed rises up to 1GB/second. The frequency
evolves with the Cat6 up to 250MHz along with the
maximum speed of 10GB/second. For achieving
this speed, Cat6 compromises with its
length. All three cables have the maximum
length of 100 metres, but for achieving
10GB/second, the length reduces to 55
meters. CAT6A is the fastest amongst these
cables in terms of speeds and frequency. Its
length too, unlike the CAT6 remains 100 meters
even

when it is transmitting 10GB/second. It has a
limitation though. The higher frequency up to
500MHz eliminated the alien crosstalk, which
could enhance the longer ranges up to
10GB/second. Twists and Turns Mystery Alexander
Graham Bell while discovering the telephone
invented the twists and turns in the cable.
For increasing the range and reducing the
interference, the cable has twists at regular
intervals. This principle of twisted pair of
wires became the basis for our Ethernet
Cables. There is no predefined standard for the
twists, but within a cable, there are specific
numbers of turn at regular intervals. A
cable contains more than one set of wires
and these sites have twist lengths based on
prime numbers. This is to avoid any
twists to align. Shielded Wires The primary
goal of all the cable manufacturers is to
reduce the external or internal interference
while transmission. For achieving this, the
wires underneath the sheath have shields.
It has a very higher efficiency and
cost. Nevertheless, your computer's

connection with your wall keystone Jack does
not need such high efficiency. Therefore, that
can be without shields. The shield protects from
internal cross-talk and interference. Lesser the
interference, higher the efficiency!
