The national standard network cable standard is detailed

　　The national standard network cable refers to the network cable that conforms to the national standard, also known as the cable for information technology equipment. It is a cable used to tranSMit data, voice and video signals, usually used for connection between computers, switches, routers and other network equipment. The following is a detailed description of the national standard network cable standard:

　　Type and Specifications

　　National standard network cables are mainly divided into the following types, each of which has its own specific specifications and performance:

　　Cat-5: This is the earliest network cable standard, with a transmission bandwidth of 100 MHz and support for 10/100 Mbps network speeds.

　　Cat-5e (Super Category 5 cable): Enhanced version of Cat-5, supports 1Gbps network speed, and the transmission bandwidth is also 100MHz. The material of Super Category 5 national standard network cable is usually oxygen-free copper, the core diameter is 0.51mm, and the sheath material is environmentally friendly flame retardant PVC material, and usually passes the Fluke test.

　　Cat-6 (Category 6 cable): The transmission bandwidth is 250MHz and supports 10Gbps network speed. The material of Category 6 national standard network cable is also oxygen-free copper, and the core diameter is generally 0.57mm (US standard 23AWG) or 0.515mm (US standard 24AWG), which also passes the Fluke test.

　　Cat-6a (Super Category 6 cable): The transmission bandwidth is 500MHz, and it also supports 10Gbps network speed. The Super Category 6 cable is specially designed for 10Gbps 10 Gigabit network, with a shielding layer and a thicker outer diameter than the Category 6 cable.

　　Cat-7 (Category 7 cable): Higher transmission bandwidth, up to 600MHz, supports network speeds from 10Gbps to 100Gbps. Category 7 cable has similar performance to Super Category 6 cable, using pure copper 8-core and shielding layer.

　　II. Main features

　　Fast transmission speed: The national standard network cable uses high-quality materials and technologies to achieve faster data transmission speeds and ensure the stability and reliability of data transmission.

　　Strong anti-interference ability: The national standard network cable adopts shielding and anti-interference technology, which can effectively suppress the interference of interference signals and ensure the integrity of data transmission.

　　Reliable quality: The national standard cable uses high-quality materials and strict quality control, resulting in stable and reliable performance and durability.

　　Wide range of applications: National standard network cables are suitable for various occasions, including homes, offices, data centers, etc., and have important application value in the field of network communication.

　　III. Purchase suggestions

　　Select the type according to your needs: When selecting a national standard network cable, you should choose the type that suits your needs. For example, for home wiring, super-Category 5 or Category 6 cables are usually sufficient; for data centers or occasions that require high-speed transmission, you may need to choose super-Category 6 or Category 7 cables.

　　Pay attention to brand and word-of-mouth: Choose well-known brands and network products with good reputation to ensure product quality and performance.

　　Check product certifications: Ensure that the selected network cable products have passed relevant quality certifications and tests, such as Fluke tests.

　　In summary, there are many types and specifications of national standard network cables, each type has its own specific application scenarios and performance characteristics. When purchasing, you should choose according to your own needs and budget, and pay attention to the brand, reputation and certification of the product.
