Some Knowledge about LAN cables
1. What is CAT5 LAN cable?
Cat.5 cable, a kind of LAN cable, is short for Category 5 cable. It is a twisted pair cable widely used in many systems such as computer networks (LAN or Ethernet), telecom and video, etc. Most Cat.5 cables are unshielded and their twisted pair design and differential signaling are quite useful for noise rejection. At present, people usually use Cat.5e cables instead of Cat.5 cables.
According to the ANSI/TIA/EIA standard for category 5e cable, the maximum length for a cable segment is 100 meters (328 feet). If longer runs are required, the use of active hardware such as a repeater, or a switch, is necessary.
2. What are the differences between cat. 5e and cat. 6 LAN cable?
The general differences between category 5e LAN cable and category 6 LAN cable are their transmission performance, and extension of the available bandwidth --100 MHz for cat.5e to 200 MHz for cat.6. Cat. 6 LAN cables can improve transmission performance and have superior immunity from external noise. Systems operating over category 6 cabling will have fewer errors.
According to research, 80 to 90 percent of all new installations will be cabled with cat6 LAN cable nowadays. However, Cat5e is still important at present.
3. Do different colors for LAN cables have different meaning?
There is no convention for the colors of LAN cable covers. They are just used to organize cables in situations where many of them are used together. Different colors of LAN cables are used to distinguish their different connections or floors. There are no functional differences between LAN cables with different colors, and you can use whatever color you like when connecting the cables. The color can help your troubleshooting and save your time to figure out the wrong cable.
