There are
many Improvements of Cat3, Cat5, Cat5e and Cat6 in the passing years, and a
little compression b/w the performances and structures of these networking
cables.
CAT3 Networking Cables:
In
the early 1990′s CAT3 cables were used for house or office wirings. Category 3 cable is known as Cat3. This cable supports the frequency 16MHz
and it carries communications
data up to 10 Mbit/s. Now it is using for two-line phone. It supported 10Base-T.
CAT5
Networking Cables:
Category
5 known as Cat 5 cable, Cat5 cable supports the frequency up to 100MHz and it
has 4-twisted pair. Cat5 supported 100BASE-T.
It has two varieties:
1.
Unshielded Twisted Pair (UTP)
2.
Screened Twisted Pair (SCTP)
Screened
Twisted Pair (SCTP) type was widely used in the world and which Screened
Twisted Pair (SCTP) to provide a measure of extra safety against interference,
but it is rarely used outside of Europe.
And
I will be explaining about UTP in Cat6 specs.
Cat5e Ethernet Cable:
The specification of category/cat5e improves upon the cat 5.
Category
5e known as Cat 5e cable, it fulfills higher standards of data transmission.
Cat5e Ethernet cable is supports the frequency up to 350MHz and Cat5e supported
1000BASE-T. It also has 4-twisted pair.
It
has two major types:
1. Cat5e Plenum (CMP) cable
2. Cat5e non-plenum (CMR)
cable
CMP
is stands for Communications Plenum Cable
CMR is stands for Communications Riser Cable
The most common cable in
United States is Plenum because it is low smoke. CMP cable is best for
the Installation of Air Conditioning and Ventilating Systems. The plastic jacket of
plenum is fire-retardant. It is used for indoor and also outdoor
Cat5e non-plenum cable is also known as
riser (CMR) cable. This cable is much cheaper against plenum. Plenum is used
for in-door and out-door but riser is just used for in-door.
It
has two verities:
1. Unshielded Twisted Pair (UTP)
2. Shielded Twisted Pair
(STP)
And
I will talk about the specs of UTP and STP in cat6 plenum Ethernet cables.
Cat6
Ethernet Cable:
Category
6 is also known as Cat6, and it is the most advanced cable against cat3, cat5
and cat5e and it is the best in performance. A Cat6 cable support 10 Gigabit Ethernet, and it is able to supports the frequency up
to 550 MHz, it means it fulfills standards of higher data transmission.
It
has two major types:
1. Cat5e Plenum (CMP) cable
2. Cat5e non-plenum (CMR)
cable
I have described the specs of Plenum and
non-plenum in Cat5e Ethernet Cables.
It
also has two verities like cat5e cable:
1. Unshielded Twisted Pair
(UTP)
2. Shielded Twisted Pair
(STP)
UTP
is standards for all categories like cat3, cat5, cat5e and also for cat6. And
also it is found in telephone systems. And this cable is most common
cable used for networking, UTP is using for video applications and also many
cameras providing UTP out-put.
Shielded
Twisted Pair (STP) Cable is introduced by IBM Cabling Systems. This type of
cable protects the EMI from exiting and entering the wire and it is also
protects the neighboring pairs from crosstalk.
