5. RJ 45 stands for Rejected Jack 45.
TRUE
FALSE
False, Ma’am!
Very good!
B. Motivation Let us play a game entitled
“I-Arrange”.
I will show you first a video about color The students watch and perform

strips of paper according on the video that you
have watched. After arranging, you will post it
on the board. The first group to post wins.
INTRODUCTION Do you have any idea what is our next topic all Ma’am I think our topic for today
C. Presentation of about? will somehow talk about arranging
the Lesson color pattern.
What are those strips of papers? I think it represents the wires of a
cable.
Very good!
As we go through with our discussion, we

Objectives we have to attain in our 60-minute lesson.
At the end of the students are
expected to:
A. familiarize the color
configuration of wires used
in straight-through LAN
cable;
B. identify the steps in making
So we will be working hand in hand in order to a working LAN cable, and:
achieve all of these. C. perform straight-through
LAN cable

E. Unlocking of Let me first introduce to you some words that
difficulties will help you to understand the topic.
So, the first word is Network. Please read the Network is a system of
meaning of “Network”, Darlyn computers and other devices that
are connected to each other.
Thank You Darlyn!
The second word is Cable. Please read the Cable is a medium through which
meaning of Cable, Ella. information usually moves from
one network device to another.
The third one is the UTP cable. Please read UTP is stands for Unshielded
David. Twisted Pair cable. It is the most
common and generally the best
option for school/office networks.
INTERACTION Today were going to deal with one of the three
types of cable which is the Unshielded twisted
F. Lesson Proper Pair or known as UTP cable.
Mila Rose kindly read. UTP cable is made up of a bundle
of twisted pairs. The twisted pairs
are small 22- or 24- american wire
gauge (awg) sized wires twisted
around each other.
The wires are typically made of copper with
polyethylene (PE) or FEP insulation which is
color coded depending on the application of
the cable being made.
Kindly take a look at you’re UTP cables. (The students will take a look at
their UTP cables).
What color of the UTP cable do you have? Ma’am we have the color is grey.
Thank you!
Ma’am the first type is straight-
We have three types of LAN cables. through A, next is straight-through
Kindly read the three types. B and the last one is the cross-
over cables.
Now, let’s start identifying first the color
configuration for straight-through A or your T-
568A.
The colors combinations are WG- G-WO-Bl-
WBl-O-BrW-Br.
Who wants to repeat the reading of color
configuration? Yes, David. Ma’am the color configuration for
straight through A is White Green,

Great! You can easily catch up with me. Brown.
Who wants to read the colors for straight
through B? Yes, Mikee.
Ma’am the color configurations are
TIA/EIA 568B: OW-O GW-Bl-BlW-
Indeed! That is correct. G BrW-Br
We also have the third one the cross over
LAN Cable. What do you think is the
combination of the cable wires? Ma’am, cross over is the
combination of the straight

straight thru B.

A Cross-over connection on the other hand is
a combination of both connection TIAs that is
used to connect similar devices.
Is there any clarifications?
Now we are going to perform how to do the
cable. None ma’am.
Steps in Creating a Working Cable.
1. Prepare the needed materials.(Ex.
RJ45, Crimping Tool, LAN Tester and
UTP Cable)
2. Strip the outer jacket of the cable by
at least 2 inches using the wire
stripper.
3. Untwist the twisted pair wires.
4. Arrange the wires of the desired (The students are attentively

Over).
5. Cut the wires in 0.5 inch.
6. Slowly insert it to the RJ45.
7. Using the Crimping Tool, lock the
RJ45 to the UTP Cable.
8. Then Check the created cables using
the LAN Tester.

H. Generalization/ How did you find your activity in network Ma’am doing cabling is difficult
Valuing cabling? speci ally that this was our first
time doing network cabling.
Yes, Francis
Thank you for sharing.
Cabling for the first time is really tough but if
you practice a lot you will find it very easy the
next time you do it.
Can you now identify and perform the steps in Yes ma’am we can now identify

Ma’am I think the importance of
cabling is that, it makes the
connection for each computer
Very good! That is correct. easier and faster unlike during the
times networking was not yet
Are there still any learning gathered? invented.
Ma’am we are doing network cable
