Before understanding the meaning of super five-cable, let's first introduce the common types and characteristics of cable. Since most of the network cables we use now are twisted pairs, let's talk about the classification of twisted pairs: twisted pairs in computer local area networks can be divided into two categories: unshielded twisted pairs (UTP) and shielded twisted pairs (STP): STP is wrapped with a layer of metal material to reduce radiation and prevent information from being eavesdropped, with high data transmission rate, but expensive and complicated installation; UTP has no metal shielding material, only a layer of insulating rubber, which is relatively cheap and flexible in networking. Therefore, we use UTP except in some special cases.
UTP used now can be divided into three categories, four categories, five categories, super five categories, six categories and super six categories. Among them, three types of UTP meet the requirements of Ethernet (10Mbps) and are important transmission media in early networks; Because the standard of level 4 UTP is later than level 3 UTP, and the transmission performance is not much improved compared with level 3 UTP, it is generally less used. Five types of UTP have become the preferred media for fast Ethernet (100Mbps) because of their low price and high quality. Ultra-five UTP is used for Gigabit Ethernet (1000Mbps).
What do you mean by super category 5 network cable?
Super-Category 5 network cable has small attenuation and crosstalk, and higher attenuation crosstalk ratio (ACR) and signal-to-noise ratio (StructuralReturn? Loss), smaller delay difference, and greatly improved performance. Class V network cable is mainly used for Gigabit Ethernet (1000Mbps). This so-called "five types of UTP" can't reach the data transmission rate of 100Mbps, and the highest is 10Mbps or 16Mbps. The standard logarithm of the super-Category 5 network cable is 4 pairs.

Ampere network cable is a kind of cable used for network communication. Ampere network cable, as the trunk cable of network transmission, has excellent transmission performance, strong mechanical performance, good temperature effect, stable electrical performance, low transmission delay, small volume, good impedance, excellent crosstalk, return loss and isolation, and low insertion loss. Amp cables are mainly divided into five categories and six categories, shielded and unshielded cables.
High-performance super class 5 unshielded cable, with mature and stable performance, meets various performance requirements of users and is the best representative of first-class quality of Amp wiring.
The solution prides itself on its leading position in technology, and Amp Laboratories keeps its leading position in technology for a long time by hiring world-class engineers and scientists. Amber. The laboratory has more than 600 patents and innovative application records around the world. Its goal is to take the lead in opening the market for next-generation products and innovative systems. AMP Lab has been the pioneer of all types of systems for many years, including 3, 4, 5 and 6. Representatives of AMP Laboratories are also active participants in various major standard-setting institutions around the world.
Transmission distance of super-category 5 network cable
The 100 meter transmission distance limit of CAT cable refers to working on Ethernet protocol. The essential reason lies in the error retransmission mechanism of TCP/IP protocol. After a node sends data, it needs to wait for a peer-to-peer response to continue sending, but the transmission speed of electrical signals in the medium is limited. The electrical signal must be transmitted twice as long as the cable length within a given time limit to complete a complete transmission response. If the response is overtime, it will be judged as data loss by the protocol and then retransmitted. Too long cables or cables with poor quality (mainly cables with low signal transmission speed) lead to frequent timeout of Ethernet signal transmission response. Authentic amber? Under the fast Ethernet protocol, CAT5 cable can still be used for the transmission distance of 100M, but this does not mean that other brands of cables can also be used for the same transmission distance. The transmission limit 100M when the CAT cable carries the fast Ethernet protocol is only a safe value. In practical work, we usually control the length of the CAT5 cable in the horizontal wiring system to about 70 meters to 90 meters, regardless of the brand of the cable, because this can ensure the safest network performance.
Transmission speed of super-category 5 network cable
The typical rate of Category 5 and Super Category 5 lines is 100Mbps. "transmitting about 10MB of data per second"
Difference between Super Category 5 Network Cable and Category 6 Network Cable
What does "super five categories" mean? Super five categories? Unshielded twisted pair (UTP-Unshielded? Twisted? Pairing)
Unshielded twisted pair cable consists of several twisted pairs and a plastic sheath. Five categories refer to five different quality levels defined by the International Electrical Industry Association for twisted-pair cables.
Super-five unshielded twisted pair is a cable that appears after improving some properties of the existing five types of shielded twisted pair. Many performance parameters such as near-end crosstalk, attenuation crosstalk ratio and return loss have been improved, but its transmission bandwidth is still 100MHz.
Category V twisted pair also uses four winding pairs and 1 tensile cable. The color of the pair is exactly the same as that of the five types of twisted pair, namely, white orange, orange, white green, green, white blue, blue, white brown and brown. The diameter of bare copper wire is 0.5 1mm (wire gauge is 24AWG), the diameter of insulated wire is 0.92mm, and the diameter of UTP cable is 5 mm.
Although the ultra-five unshielded twisted pair can also provide transmission bandwidth as high as 1000Mb/s, it often needs the support of expensive special equipment. Therefore, it is usually only applied to 100Mb/s fast Ethernet to realize the connection between desktop switch and computer. If you don't plan to upgrade your network to Gigabit Ethernet in the future, you might as well use super-five unshielded twisted pair in horizontal wiring.
"Six categories" refers to six categories of unshielded twisted pair.
The parameters of six types of unshielded twisted pair are greatly improved, and the bandwidth is extended to more than 250MHz. There are some differences in appearance and structure between the six-category twisted pair and the five-category or super-five-category twisted pair. Not only is the insulated cross skeleton added, but four pairs of twisted pairs are placed in four grooves of the cross skeleton respectively, and the diameter of the cable is also thicker.
The cross skeleton in the center of the cable rotates with the change of length, and the four pairs of twisted pairs are stuck in the grooves of the skeleton to maintain the relative position of the four pairs of twisted pairs, thus improving the balance characteristics and crosstalk attenuation of the cable. In addition, the balanced structure of the cable ensures that it will not be damaged during installation. The bare copper wire diameter of the six types of unshielded twisted pair is 0.57mm (the specification is 23AWG), the insulated wire diameter is 1.02mm, and the UTP cable diameter is 6.53mm.

The price of more than five kinds of network cables
The best-selling ultra-five network cable on the market now is Amp. The stranded length of adjacent pairs of Ampu VI network cables is above12.7 mm. Generally, the denser the stranded wires, the stronger the anti-interference ability. Compared with other transmission media, network cable is limited in transmission distance, channel width and data transmission speed, but its price is lower. The structure of Anpu network cable is made of four insulated steel wires wrapped in tight sleeves of different colors, such as orange, blue, green and brown. Each tight steel wire is wrapped with white tight steel wire, and then wrapped with environmental protection and flame retardant PVC sheath.
The price of ultra-category 5 network cable has been relatively stable, but with the continuous expansion of the scope of use, it has also received more attention.
