5. Review of the past lesson
Class, can you still remember our
past lesson? Yes sir.
What was our past lesson all about?
It’s about the different network cabling
Very good! tools sir.
Now, can you give me some examples
of these tools and materials? UTP, RJ-45, network cable tester,
crimping tool, wire stripper and punch
Very good! down tool.
B. Motivation
I have prepared a short video clip. At the
end of the video, I will ask you some
questions.
Is that clear? Yes sir.
A video clip about computer networks will The students watch the video clip.
be shown on the projector.
After showing the video clip, the teacher
will ask the students.
Students, what can you say about the video It is all about how the computer networks
clip you have just watched? connect and work.
Yes, it’s all about computer networks, how
computers connect and work. And the video
is actually related to our topic for today.
Now, for today’s lesson we will identify and
create a network cabling, specifically the
straight through cable.
Before we start our lesson let me present to
you the learning objective.
C. OBJECTIVES:
At the end of the lesson, the students should
be able to:
Identify the steps in creating a
straight-through cable.
Create a straight-through cable using
T568B standard.
Value the importance of following
safety precautions while working.
Are our objectives clear? Yes, sir!
D. Lesson Proper (Using slideshow
presentation)
Alright, let us define some terms as we will
encounter them throughout the discussion.
Ethernet cable – a network cable used to Students will read the definition
connect devices on local area networks such as
PCs, routers, and switches.
Computer network – is composed of two or Students will read the definition
more computers that share data and resources.
Crimping – process joining two pieces of Students will read the definition
metal (usually a wire and a metal plate) by
deforming one or both of them to hold the
other.
Hub – used as the central object on which Students will read the definition
computers and other devices are connected.
Local Area Network (LAN) – a group of Students will read the definition
interconnected computers that are under the
same administrative control.
Our lesson for today is about Ethernet/Lan
cabling. Particularly, the straight-through
cabling. We will also be discussing when to
use and how to create a straight-through
cable.
Students will read the definition.
Ethernet/LAN Cabling - the process of
creating cable used to create a network that
interconnects computers and other network
devices.
Alright, Ethernet/LAN cabling is the process
of creating cables used to connect a network.
Now, there are two types of Ethernet/LAN
cables, and what are these?
Types of Ethernet/LAN Cables
1. Straight-through Cable
2. Crossover Cable
Now, there are two types of Ethernet/LAN
cables. The first one is straight-through cable
and the other is the crossover cable. But for
this session, we will be focusing on the
straight-through cable.
Students will read the definition.
So, what is a straight-through cable?
Straight-through cable - a type of twisted
pair cable that is used in local area networks to
connect a computer to a network hub such as a
router.
It is said that the straight-through cable is
used to connect a computer to a network hub
such as a router. Therefore, when do we use
straight-through cable?
The teacher will give examples of the
instances that a straight-through cable will be
used.
Students, these are the connections that use
straight-through cable.
Straight-through cables are used to
connect different devices.
Now, class from these examples, what have
you observed?
Very good.
We use straight-through cable when
connecting two different devices.
Now you know when to use straight-through
cable. The next thing is, how do you create a
straight-through cable?
Now, when terminating or splicing a straight-
through cable we must follow industry
standards. There are two color combination
standards used in creating a straight-through
cable. The first is the T568A and the other one
is the T568B color combination. So, for Yes sir
instance, if we use T568A on one side of the
cable we also use the same code on the other
side. Did you get it?
Color Codes for Terminating a Straight-
through Cable
1. T568A
2. T568B
T568A
T568B
However, it is a common practice in the
industry that the T568B color code is used for
straight-through cables. Which means, we will
be using the T568B in creating our straight- Yes sir.
through cable, although, T568A can also be
used in creating a straight-through cable.
Do you understand class?
Alright, we already identified what color code
will be used for our straight-through cable.
Now, I will demonstrate to you how to make a
straight through cable. But before making the
straight-through cable, let me remind you of
the safety precautions.
Safety Precautions:
Avoid horse playing
Use the proper tool Yes sir.
Always be on task
Be vigilant
Am I clear?
Now, here are the steps in creating a straight Yes sir.
through cable. You should carefully observe
as I demonstrate because after this, you will
be making your own straight-through cable.
Am I understood?
The teacher will demonstrate to the class how
to create a straight-through cable.
Steps in Creating a Straight-through Cable
1. Prepare all materials needed.
2. Remove the outer jacket/insulation of
the cable to about one inch.
3. Untwist the cable pairs, spread the
wires, and arrange them based on
T568B color code.
4. Straighten and flatten the wires
between your thumb and forefinger.
5. Trim the untwisted wires to about ½
to ¾ of an inch.
6. The exposed copper pins on the RJ-45
connector must be facing towards you.
Ensure that the wires are in order from
left to right starting from pin 1.
7. Insert the wire firmly into the RJ-45
connector until all wires are pushed as
far as possible into the connector.
8. Visually inspect the cable and ensure
the right wire codes match the pin
numbers and the eight wires should be
pressed firmly against the end of the
RJ-45 connector.
9. Place the RJ-45 connector and cable
into the crimping tool and crimp the
RJ-45 connector until you hear a click
from it.
10. Repeat all the previous steps with the
other end of the cable.
11. Test the cable using the network cable
tester.
Yes sir.
Students, were you able to follow the No sir.
procedure?
Do you have questions or clarifications?
E. Application
So, it’s now your turn to make your straight-
through cable. You already have your
groupings. You also have the tools and
materials with you. If you have any questions
during the activity, you should raise your
hand for you to be recognized. Also, minimize
your voice and avoid unnecessary noise while
performing the activity. Yes sir
Am I clear? The students are doing the activity.
The teacher is facilitating the activity.
After the activity. Yes sir.
Yes sir.
Did you enjoy our activity?
Did you learn from our topic today? No sir.
Do you have any questions or clarifications
about our topic today?
F. Generalization We use straight-through cable when
connecting two different devices.
When do we use a straight-through cable?
Connecting a computer and a router.
Give an example of a connection that uses
straight-through cable. The color standards used are the T568A
and T568B.
What are the 2 color standards used in
straight-through cabling? T568B is the color standard used in a
straight-through cable.
What color standard is commonly used in
industry in creating a straight-through cable? The color combination is white-orange,
orange, white-green, blue, white-blue,
What is the color combination of the T568B green, white-brown, brown.
color standard starting from pin 1 up to pin
8? T568B sir.
For instance, I use T568B on this end of the
cable, what color code will I use on the other The students enumerate the steps.
