LAN Cable Wiring and Testing

This video tutorial on Obi Teknik Channel demonstrates how to make LAN cables, specifically straight and cross types. It begins with an introduction to the uses of each cable type, followed by a list of necessary tools and materials. The tutorial provides a detailed, step-by-step guide on creating both straight and cross cables, including the correct color order and crimping techniques. The video concludes with testing the cables using a LAN tester to ensure proper functionality.

What is the primary use of a straight LAN cable?

• Connecting a switch to a switch

• Connecting a computer to a switch

• Connecting a laptop to a laptop

• Connecting two similar devices

Which tool is essential for attaching an RJ45 connector to a LAN cable?

• Screwdriver

• Hammer

• Crimping tool

• Pliers

What is the first step in making a straight LAN cable?

• Crimping the connector

• Testing the cable

• Stripping the cable

• Arranging the wires

How should the wires be arranged for a straight cable?

• White Orange, Orange, White Green, Blue, White Blue, Green, White Brown, Brown

• White Green, Green, White Orange, Blue, White Blue, Orange, White Brown, Brown

• White Blue, Blue, White Orange, Green, White Green, Orange, White Brown, Brown

• White Brown, Brown, White Blue, Green, White Green, Blue, White Orange, Orange

What indicates a successful test of a straight cable using a LAN tester?

• Random LEDs light up

• No LEDs light up

• All LEDs light up in sequence

• Only one LED lights up

What might happen if the cable's outer jacket is not crimped properly?

• The cable will be too short

• The cable will change color

• The wires may become loose

• The cable will not fit the connector

What is the main difference in wire arrangement between a straight and a cross cable?

• The color of the wires

• The length of the wires

• The order of the wires

• The type of connector used

Which wire color sequence is used for the second end of a cross cable?

• White Blue, Blue, White Orange, Green, White Green, Orange, White Brown, Brown

• White Orange, Orange, White Green, Blue, White Blue, Green, White Brown, Brown

• White Brown, Brown, White Blue, Green, White Green, Blue, White Orange, Orange

• White Green, Green, White Orange, Blue, White Blue, Orange, White Brown, Brown

What is the purpose of testing a cross cable with a LAN tester?

• To measure the cable's weight

• To check the cable's length

• To ensure the wires are connected correctly

• To verify the cable's color

What should you do if the LAN tester shows incorrect connections?

• Ignore the results

• Re-crimp the connectors

• Cut the cable in half

• Change the cable's color
