1. 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 cable’s 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?

2. 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
The 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!
