Network cable Reflection & Notes

________________________________________
The goal of this lab is to demonstrate that you understand the core concepts involved in how to build a cable. After you view the video of construction of the network cable, answer the following questions.
1. What is the cable model name that we built in the video?
2. In your own words, describe the layout of the wires in the cable in terms of the color and style?
3. Why do we use Twisted Pair (TP) wires in the cable?

Sure! Here are the answers to your questions based on typical information related to network cable construction.

  1. Cable Model Name: The cable model built in the video is likely to be Category 5e (Cat 5e) or Category 6 (Cat 6) twisted pair cable, which are commonly used for network cabling.

  2. Layout of the Wires: In a typical twisted pair cable, there are four pairs of wires, each twisted together to minimize interference. The standard color coding for these pairs is as follows:

    • Pair 1: White/Blue and Blue
    • Pair 2: White/Orange and Orange
    • Pair 3: White/Green and Green
    • Pair 4: White/Brown and Brown Each pair’s wires are twisted together, which helps to reduce crosstalk and electromagnetic interference. The wires are often arranged in a specific order when terminating the connectors, following the T568A or T568B standards.

  3. Why Use Twisted Pair (TP) Wires: Twisted pair wires are used in network cables primarily because they help reduce electromagnetic interference (EMI) and crosstalk from adjacent pairs and other electrical signals. The twisting of the wires balances out the electromagnetic fields produced by each wire, which minimizes the impact of external noise and improves the cable's performance over distances. Additionally, twisted pair cables are generally more cost-effective and flexible compared to other cable types like coaxial or fiber optic cables.
