LAN cables are the Ethernet transmission media connecting network devices in
your computer network. Is very useful if you know better about before you make
a lan cable network design. Design a great network cables, a supporting element
which makes computer networking lan you will easily maintained and reliable. So
very useful lan cable network in reality. The following are the kinds of lan cable
commonly used in lan networks.
1. Coaxial LAN Cables
Lan coaxial cable used
in Ethernet 10Base2
and 10Base5 a few
years ago. 10Base5
refers to the temporary Thicknet 10Base2 10Base5
refers to the first use because thinnet
lan cable coaxial
thicker.
Initially Ethernet network based
on coaxial lan
cable which can
stretch up to 500
meters in one segment.
Lan coaxial cable
is expensive, and only up to a maximum speed
of 10 Mbps only. Coaxial cable lan
is now unpopular.
2. Fiber Optic
Fiber optic is the latest medium for
transmission within standard Ethernet lan
cable. The main difference
in terms of functionality between
fiber optic cables and electric cables
are partially follows:
- Distance farther
- Much more expensive
- Less magnetic interference, making it more secure
- Able to support speeds up to 10 Gigabits
There are two kinds of lan cable in the optical device:
- Multimode (MM), using the size of the larger diameter fiber optic
- Single mode (SM), using a very small diameter fiber optic. This type is very expensive due to the fabrication process more precise. Optic cable can reach much longer than on the type of optic MM.
Optic Connectors
To transmit data via the optic lan cable you need a single optic strand to
one direction. You need two optic strand for both directions every 2 to send
and receive.
We return to our initial scenario, how to connect each building using a lan
cable based on our knowledge of the above lan cable? The following image is a
picture of best practice how to connect the two buildings with a lan cable, in
the scenario we use the lan cable UTP Cat5e outdoor. You can use a lan cable
UTP crossover. Crossover cable to connect to each other on the trunk ports of
switches to be connected. You need to configure the port that serves as a trunk
port.
Drop cable is a cable that connects any computer with a switch. Lan cable
is supposed to use Cat 5e UTP cable with each end has RJ-45 connector. Minimum
lan cable is 0.6 meters and the maximum is 100 meters.
Wall jack is similar to the connection point that often we find in the
phone, so that it can connect network lan cable UTP RJ-45.
Patch cable is UTP cable segments are used to connect to a network
interface card or a wall jack to connect other parts of the network cable
installation. Patch panel is a panel that provides a multi-port connector that
channel cables to devices or other connecting hardware such as switches.
3. UTP (Unshielded Twisted Pair)
and STP (shielded
twisted pair)
There are two types of cable
with copper wire
is that STP
and UTP, but
the most popular is
the lan cable UTP. Lan
cable UTP is
the most popular which
consists of 4 pairs
of wires wrapped around each
other with a special color code standard
and insulated with
plastic.
Levels of UTP cable is indicated by its
many winding or
torsion every single
inch, the low level
of attenuation, lack the level of interference and crosstalk symptoms.
Maximum length in one segment of the lan cable is 100 meters away, if it
is longer than 100
meters, then you are not able to guarantee the
high level of attenuation. Speed
that can be
achieved is up to 1 Gigabit is of type UTP Cat5e lan cable,
which is the amount of twisting or winding
of the cable pair
a little more every single inch and added more as a single
nylon cable jacket
insulation. So once again the grade of UTP cable is determined by the number
of torsion in every single inch.
Standard UTP
- Lan cable UTP Cat 1, used for telephone networks.
- Lan cable UTP Cat 2, a maximum speed of 4 Mbps, originally intended to support Token Ring over UTP.
- Lan cables Cat 3, with a maximum speed of 10 Mbps. Lan cable can be used for telephone and an option jarigan lan cable UTP past.
- Lan cable UTP Cat 4, the maximum speed is 16 Mbps, faster version of the commonly used Token Ring network.
- Lan cable Cat 5, maximum speed of 1 Gigabps, very popular for desktop lan cable.
- Cat 5e UTP lan cable, with a maximum speed of 1 Gigabps, lower emissions, more expensive than Cat 5 would be great but for Gigabit networks.
- Lan cable UTP Cat 6, maximum speed is 1 + Gigabps, intended as a substitute for the ability to support Cat 5e-2 multigigabit speeds.
Identification UTP
You should be familiar with both the cabling to be able to identify
by examining its pin-2. There are actually two kinds of standards are:
- T568-A is a lan cable UTP straight through type, both ends of the cable placement on pin-2 RJ-45 connector is the same.
- T568-B is a lan cable UTP type of cross-over. You can take a closer look at the cross-over cable, pins 2 and 6 couples and couples pin 1 and 3 swapped places.
Connecting Devices
The rules of the
use of this cable is as follows, if
for connecting two
different types of devices, use the lan cable
UTP straight-through. Meanwhile, if you connect
two similar devices, use a
cross-over LAN cable.
Anyway all your friends, ... to be clear about the practice in the form of
an image, you only need to access google images, because many other publiser
create a link on the LAN cable problem. Enjoy Man !!
