What are yellow and blue cables?
Yellow and blue cables are types of Ethernet cables used for networking purposes. They are used to connect devices such as computers, routers, and switches to form a local area network (LAN). These cables are categorized based on their bandwidth capacity, and the yellow and blue colors refer to the type of twisted pair wiring used inside the cable.
The yellow cable is typically a Category 5 (Cat 5) or Category 5e (Cat 5e) cable, which supports up to 1 Gbps of bandwidth. It is commonly used for general-purpose LAN applications. On the other hand, the blue cable is typically a Category 6 (Cat 6) or Category 6A (Cat 6A) cable, which supports up to 10 Gbps of bandwidth. It is commonly used for high-speed LAN applications, such as data centers and high-traffic networks.
What is the difference between yellow and blue cables?
The main difference between yellow and blue cables lies in their bandwidth capacity and the type of twisted pair wiring used inside the cable. Yellow cables typically have a lower bandwidth capacity, making them suitable for general-purpose LAN applications. They are also less expensive than blue cables. Blue cables, on the other hand, have a higher bandwidth capacity, making them suitable for high-speed LAN applications that require faster data transfer rates.
Another difference is the gauge of the wire used in the cables. Yellow cables typically have a smaller gauge wire, which makes them more prone to attenuation and interference. Blue cables, on the other hand, have a larger gauge wire, which makes them less prone to attenuation and interference. This results in a more reliable and stable connection.
