Takeaways

• 😀 UTP cables, commonly known as LAN cables, are used for data transmission in local area networks (LAN).
• 😀 UTP stands for Unshielded Twisted Pair, indicating that these cables lack aluminum protection compared to other twisted-pair cables.
• 😀 UTP cables consist of 8 cores with different color codes, each serving a specific function, such as data transmission and voltage conduction.
• 😀 There are different types of UTP cables: straight, cross, and rollover cables, each with distinct wiring arrangements.
• 😀 Straight cables connect different devices, while cross cables connect similar devices, and rollover cables are used for console-type connections.
• 😀 To prepare a UTP cable for crimping, tools such as crimping pliers, an RJ-45 connector, and a UTP cable are required.
• 😀 The crimping process involves stripping the cable jacket, straightening the wires, and then securing them into the RJ-45 connector using a crimping tool.
• 😀 It’s important to handle cables carefully, ensuring the materials are of good quality to avoid connection issues during installation.
• 😀 In the event of a damaged cable, a workaround involves connecting cables with fewer cores, though this limits connection speeds to 100mbps.
• 😀 Testing the crimped cables involves connecting them to a network device and checking if the lights are on to confirm proper functionality.
• 😀 The order of wires in the connectors should follow the correct standard for the cable type being used, ensuring proper data flow and connectivity.

Q & A

What is UTP cable and what does it stand for?

UTP stands for Unshielded Twisted Pair. It is a type of network cable used for data transmission in computer networks, specifically for local area networks (LANs). It does not have aluminum protection like other twisted-pair cables.

What are the four main components of a UTP cable?

The four main components of a UTP cable are: 1) Cable jacket, 2) Cable thread, 3) Insulator, and 4) Copper wire or conductor.

What do the different colored wires in a UTP cable represent?

Each color in the UTP cable represents a specific function: 1) White-Orange and Orange: Data packet conductor. 2) White-Green and Green: Data packet conductor. 3) White-Blue and Blue: Data packet conductor. 4) White-Brown and Brown: DC voltage conductor.

What are the different types of UTP cables, and what are they used for?

The different types of UTP cables are: 1) Straight Cable: Used for connecting different devices, such as a router to a computer. 2) Cross Cable: Used for connecting similar devices, such as a computer to a computer or a router to a router. 3) Rollover Cable: Used to connect network devices with consoles, like a switch to a printer or projector.

How do you prepare a UTP cable before crimping?

To prepare a UTP cable, you should first peel the cable jacket, which can be done by hand, using a tank, a cable sheath, or a mini screwdriver. After peeling, straighten the twisted wires using hand pressure, a cable sheath, or pliers.

What tools are needed for crimping a UTP cable?

The tools needed for crimping a UTP cable include crimping pliers, a UTP cable, and an RJ-45 connector.

What is the correct crimping sequence for a straight cable?

The crimping sequence for a straight cable follows this order: 1) White-Orange, Orange, 2) White-Green, Green, 3) White-Blue, Blue, 4) White-Brown, Brown.

How does crimping a cross cable differ from a straight cable?

For a cross cable, the sequence for the first connector is the same as a straight cable, but for the second connector, the color arrangement is reversed between white-orange/green and white-green/orange.

What should you do if you encounter a damaged cable in the field?

If you encounter a damaged cable, you can still make a connection by using only four wires (White-Orange, Orange, White-Green, Green) for a maximum speed of 100 Mbps. For higher speeds, it is recommended to use all eight wires.

How can you test a crimped cable to ensure it works?

To test the crimped cable, plug it into a device like a hub. If the connection is successful, the indicator lights should turn on. If the cable is for console connections (like a rollover cable), it should be plugged into a VGA port or similar device.
