How to choose most suitable network cable?
How to choose most suitable Network Cable?1. Network cable category
Common network cable types include Category 5e, Category 6, Category 6a, Category 7, and Category 8. As the number increases, the performance of the network cable is gradually improved.
Cat5e: Enhanced signal transmission performance, supports 1000Mbps (Gigabit Ethernet) transmission rate, the bandwidth is also 100MHz, and the maximum transmission distance is also 100 meters.
Cat6: Provides higher bandwidth (250MHz), supports 10Gbps transmission rate (under certain conditions), and the maximum transmission distance is usually 100 meters (Gigabit Ethernet). It can support higher transmission rates (10 Gigabit Ethernet) in shorter distances (such as 37-55 meters).
Cat6a: further enhances performance, provides 500MHz bandwidth, optimizes crosstalk and attenuation performance, supports 10Gbps transmission rate, and has a maximum transmission distance of 100 meters.
Cat7: provides 600MHz bandwidth, supports 10Gbps transmission rate (40Gbps and 100Gbps have limited transmission distance), and has a maximum transmission distance of 100 meters.
Cat8: provides 2000MHz bandwidth, supports up to 25Gbps/40Gbps transmission rate, but the maximum transmission distance is limited to 30 meters.
Network cables are also divided into shielded (STP) and unshielded (UTP).
STP: reduces electromagnetic interference through metal layer or aluminum foil wrapping, suitable for environments with extremely high signal quality requirements, such as industrial control, data centers, etc. Due to the presence of the shielding layer, STP has lower signal attenuation, especially in high-speed data transmission, and can effectively reduce crosstalk and improve signal clarity. However, the cost of STP is higher than UTP, and the installation is relatively complicated, and it is necessary to ensure that the shielding layer is properly grounded.
UTP: Low cost, easy to install, suitable for general homes and small offices. UTP's anti-electromagnetic interference ability is relatively weak, but it is sufficient for use in most application environments.
Length: The length of the network cable is also an important factor affecting the signal quality. Generally speaking, the length of the network cable should not exceed 100 meters to ensure that the signal attenuation is within an acceptable range.
Material: The material of the network cable affects its durability and transmission performance. High-quality network cables use high-purity copper cores (such as oxygen-free copper), which have good conductivity and stable signal transmission. Although recycled copper network cables are cheap, their high-speed transmission capacity is slightly weaker; copper-clad aluminum network cables are cost-effective, but their service life is short; and materials such as aluminum and iron age faster.
4. Compatibility and certification
When choosing a network cable, you also need to consider its compatibility with network equipment. Make sure that the network cable meets relevant industry standards, such as TIA/EIA standards. This helps to ensure the quality and performance of the network cable.
5. Brand and price
Brand: Choose a well-known brand of network cable, such as CASVIEW. Big brands have a good reputation and credibility in the market, and the product quality is guaranteed.
Price: Price is not the only criterion for measuring the quality of network cables, but generally speaking, the price of high-quality network cables is relatively high. When purchasing, you can choose the right network cable according to your budget and needs.
In summary, when choosing a network cable, you need to consider the category, shielding and non-shielding, length and material, compatibility and certification, as well as brand and price. Only according to actual needs and environmental characteristics can you choose the most suitable network cable to provide strong protection for network transmission.
