DIFFERENCES IN STRAIGHT CABLE AND CROSS
Detailed Explanation Regarding Differences With Straight Cable
and Cross Cable
1. Straight Cable
Straight cables are used to when
trying to connect between the computer and the hub or conversely. With other
words, this method is used when we are going to connect two or more computers,
but through an intermediary such as a hub or switch.
Straight cable is a cable that
uses the term to the same standard at both ends of the cord, can EIA / TIA 568A
or EIA / TIA 568B on both ends of the cable. Simply put, the color sequence on
both ends of the same cable. In the straight cable, pin 1 on one end of the
cable connects to pin 1 at the other end, pin 2 connected to pin 2 at the other
end, and so on.
So, when PC send data on pins 1
and 2 through a straight cable to Switch, Switch receives data on pins 1 and 2.
Well, because pins 1 and 2 on the switch will not be used to send data as well
as pins 1 and 2 on the PC, then switch uses pins 3 and 6 to send data to the
PC, because the PC receives data on pins 3 and 6.
2. Cable cross
Cross cable is used when we want to connect your computer to
another computer, or cable is used when we want to connect two computers or hub
to hub, in other words in a cross cable to connect the two devices using the
same network.
In the picture, pin 1 and 2 on
the other end connects to pins 3 and 6 on the other end B, as well as pins 1
and 2 at the end B is connected to pins 3 and 6 at the end A. Thus, pins 1 and
2 on each end of the cable is used to transmit data, while pins 3 and 6 on each
end of the cable used to receive data, because pins 1 and 2 are connected in
opposite pin 3 and 6.
FUNCTIONS CABLE
1. Function Straight Cable
Cables with this combination is used for connections between devices of
different types. for examples, as
follows:
1. Connect the computer to the switch
2. Connect the computer to the LAN on the cable modem / DSL
3. Connect the router to the LAN on the cable modem / DSL
4. Connect the switch to the router
5. Connect the hub to the router
the colors we can see in the image below:
2. Function Cable Cross
Cables with this
combination is intended for peer to peer connections between devices similar. For
example, as follows:
1. Connect the two computers directly
2. Connect 2 pieces switch
3. Connect the two pieces of the hub
4. Connect the switch with a hub
5. Connect your computer to the router

The
difference straight cable and cross in the data transmission and receipt of
data:
Shipment Data and Data Acceptance
Model Straight Cable (Delivery of data with models straight cable) is the data
sent to the hub / switch new hub restored. Transmission of data by the
network adapter will be accepted as the signal transmission of data by the hub
/ switch and the data receiver in the network adapter and receipt of data by
the hub / switch.
Shipment Data and Data
Acceptance
Model Cross Cable
(Shipping and receiving data crossover cable) from computer to
computer is delivery of data by a computer network adapter 1 will be accepted
as a signal receiver in the computer network adapter 2 and receipt of data by a
computer network adapter 1 is the delivery of data by a computer network
adapter 2.
CREATING STRAIGHT
AND CROSSOVER CABLE
To create a wired network using UTP cable, there are some
tools that we need to prepare, namely:
• UTP cables
• RJ-45 Connector
• Crimping tools
• RJ-45 LAN Tester
sample picture as below:
1. UTP Cable Straight Type
Now we will discuss how to install. The first is how to
install the type of straight UTP cable. To do this, do the following steps:
1. Peel the cable ends approximately 2 cm, so the tiny wires
that are inside look.
• Separate cables and straightens. Then stacking and trim
based on color is Orange White, Orange, Green White, Blue, Blue White, Green, White
brown, and brown. After that cut the edges so mean to each other.
UTP cable arrangement straight type you can see in the picture
below:
After the cable is arranged, take Jack RJ-45. As I said
earlier this Jack consists of 8 pins. Pin 1 of this jack is located leftmost
pin if the pin position facing you. Sequential to the right is the jack 2, 3,
and so on.
Then
insert the cables into the RJ-45 Jack in the order was as follows:
o Orange
White on Pin 1
o Orange
to Pin 2
o Green
White at Pin 3
o Blue on
Pin 4
o Blue
White on Pin 5
o Green
at Pin 6
o Brown
White on Pin 7
o Brown
at Pin 8.
Insert the cable until the tip is stuck in the jack.
Installing Jack RJ-45 cable is plugged into the mouth before
crimping pliers corresponding to part pin RJ-45 Jack is inside the mouth of the
pliers. Now flops jack before the crimping pliers until the entire pin stuck on
the cable. Usually, if the pin jack has been lodged will make a sound
"click".
Now that you've finished installing the RJ-45 jack on the end
of the first cable. For the second end of the cable, the steps are the same as
the first one end of the cable installation. To that end, repeat the steps had
to put Jack RJ-45 connector on both ends of the cable.
If it is then we test using the LAN tester. Insert the tip end
of the cable to the device, then turn it on, if the LED lights are on the LAN
tester lights up all, from number 1 to 8 means that you have been successful.
If there is one who does not turn means the possibility to pin numbers are no
problem. The easiest way that you press (press) again using the pliers. The
possibility of penetrating the pin yet. If you've hit but still do not connect,
then try to check the correspondence between the pin already 1-1 or not seen image
below:
2. Cross UTP Cable Type
How to install the UTP cable straight type I described
earlier. Now I will discuss about how to install the UTP cable cross type. How
to UTP cabling cross type virtually the same as installing UTP cable straight
type. Installation
technical about the same as before. The difference is the order of the color of
the cable at both ends of the cable. For the end of the first cable, cable
arrangement similar to the arrangement of straight UTP cable types, namely:
o Orange
White on Pin 1
o Orange
to Pin 2
o Green
White at Pin 3
o Blue on
Pin 4
o Blue
White on Pin 5
o Green
at Pin 6
o Brown
White on Pin 7
o Brown at Pin 8.
For the second end of the cable, the color composition different
from the first tip. The color composition is as follows:
• Green
White on Pin 1
• Green
on Pin 2
• Orange
White to Pin 3
• Blue on
Pin 4
• Blue
White on Pin 5
• Orange
on Pin 6
• White
Brown at Pin 7
• Brown
at Pin 8.
The final results UTP cable will cross type like this:
The conclusion is that if you install the cable UTP straight
type then the arrangement of colors on both ends of the cable are the same. As
for how the installation of UTP cross type, color composition different from
the first end of the cable ends second cable. Later, when tested using the LAN
tester, then later led 1, 2, 3 and 6 will be exchanged. If the straight type flaming
sequence, whereas there are cross type jumping. But definitely should be lit
all each led from number 1 to 8.l See image below:
