For those of you who deals in IT or want to create a local network on your own home would be familiar with UTP cable . This time OurSmartInfo will share tips on how to make Straight & Cross UTP Cable to be able to create a computer network in order to connect online to the Internet and locally.

To make UTP cable we must have the following tools :

- Crimping Plier

Crimping plierCrimping plier is a tool to cut UTP cable and connector to clamp the end of the connector , and this is very important for us who want to learn how to crimp cable , this tool is almost the same shape with regular plier that we often see or meet .


- UTP Cables

UTP Cable

We use UTP cables to connect with each other and in UTP cable there are 8 pieces of small colorful cable.

- RJ- 45 Connector

RJ-45 Connector

RJ-45 Connector is a tool that we put on the end of the UTP cable. With this we can plug the cable in the LAN port . RJ - 45 connector must be attached to the end of the UTP cable UTP cable if not then it will not be useful .

- Cable Tester

Cable TesterCable Tester is a tool to test the results of our crimped cable , if we are wrong then Cable Tester lights will not turn on and if the results are correct then our crimped cable in Cable Tester lights will turn on automatically , so this tool is very useful for us to know our crimp results .

Differences Between Straight cable and Cross cable

before we start making cables it is useful to know the function of each cable .


Straight cable is a cable that has a same way of arrangement between one end with the other end .

Standard sequence of straight cable is below the standard that is in accordance with the TIA / EIA 368B ( most widely used ) or is sometimes also used according to standard TIA / EIA 368A as follows :

straight UTP cable standard

Examples of the use of a straight cable is as follows :
Connects the computer to the switch
Connect the computer to the LAN on cable modem / DSL
Connect the router to the modem LAN cable / DSL
Connecting switch to router
Connect the hub to the router

Cross cable is a cable that has a different arrangement between the end of one with the other . Cross cable is used to connect two devices together directly. The picture below is a standard arrangement of cross cable .

Cross UTP cable standard

Examples of the use of cross cable are as follows :
Connecting 2 computers directly
Connecting 2 pieces of switch
Connecting 2 pieces of hub
Connecting the switch to hubs
Connect the computer to the router

From 8 pieces of existing wires in the UTP cable (either on a straight or cross cable ) only 4 pieces are used to send and receive data , ie cables no. 1,2,3 and 6 .



Making Straight UTP Cable

- Peel the end of the UTP cable , approximately 2 cm .

- Open the cable strands , align and follow the arrangement as standard cable image shown below .

- Once the order is according to the standard , cut and flatten the ends of the cable ,

- Put the cable is straight and aligned into the RJ - 45 connector , and make sure all cables are in correct position as follows :


Orange White on no 1
Orange on no 2
Green White on no 3
Blue on no 4
Blue White on no 5
Green on no 6
White Brown on no 7
Brown on no 8

- Make crimping using crimp tools , press crimping tool and make sure all the pins ( brass ) on the RJ - 45 connector has " bite " of each cable . usually when done will sound "click " .

Once finished at the end of this one , do it again at the other end  cable.

The final step is to check the cable that you created earlier using the LAN tester , enter each end of the cable ( RJ- 45 ) to each LAN port available on the tester , turn and make sure all of the LEDs light up according to the order of the wires we created.

Creating Cross UTP Cable

Creating a cross cable has almost the same steps with straight cable , the difference lies only in the color sequence from both ends of the cable . Unlike the straight cable that has the same color sequence at both ends of the cable , the cross cable has a different color sequences at both ends of the cable .

The first ends is same with straight cable :

Orange White on no. 1
Orange on no. 2
Green White on no. 3
Blue on no. 4
Blue White on no. 5
Green on no. 6 .
White chocolate on no. 7
Brown on no. 8

For the second end of the cable , the color composition is different from the first . the color arrangement is as follows :
Cross UTP Cable Arrangement

Green White on no. 1
Green on no. 2
Orange White on no. 3
Blue on no. 4
Blue White on no. 5
Orange on no. 6
White chocolate on no. 7
Brown on no. 8

Below is an example of the end of the UTP cable that has an RJ- 45 connector is attached properly , the cable sheath ( blue) go into the connector .

So This is how to Make Straight and Cross UTP Cable . Not too difficult, right? May this article useful.
