hsyv-5e is a Category 5e network cable; hsyv represents the structure of the line, and 5e represents Category 5e. Its transmission frequency is up to 100MHz. It is a Gigabit network cable and can be used in Gigabit networks. , and the twisting degree of the central wire pair of hsyv-5e is relatively dense, the signal transmission is fast, the quality is better, and the durability is better.

hsyv-5e is a Category 5e network cable.
HSYV-5ESpecial cable refers to Category 5e untwisted pair (UTP—Unshielded Twisted Pair) and Category 5e twisted pair.
In hsyv-5e, hsyv represents the line structure, and 5e represents Category 5e. Its transmission frequency is as high as 100MHz. It is a Gigabit network cable and can be used in Gigabit networks, and hsyv -5e center wire pair has a denser twist, faster signal transmission, better quality, and better durability.
HSYV-5E special cable Computer LAN twisted pair can be divided into two categories: untwisted pair (UTP) and twisted pair (STP):
STP is wrapped by a layer of metal material to reduce radiation and prevent information from being intercepted. At the same time, it has a higher data transmission rate, but the price is higher and the installation is more complicated;
UTP has no metal materials and is only wrapped with a layer of insulating rubber. It is relatively cheap and has flexible networking. .
Except for some special occasions (such as severe electromagnetic nuclear radiation, high transmission quality requirements, etc.) where STP is used in wiring, we generally use UTP.
The UTP currently used can be divided into Category 3, Category 4, Category 5, Category 5e, Category 6, and Category 6e. Among them:
Type 3 UTP adapts to the requirements of Ethernet (10Mbps) for transmission media and is an important transmission medium in early networks;
4 Category UTP was launched later than Category 3 because the standard was introduced, and the transmission performance has not improved much compared with Category 3 UTP, so it is generally less used;
Category 5 UTP is expensive It is low-cost and high-quality and becomes the medium of Fast Ethernet (100Mbps);
Category 5e UTP is used for Gigabit Ethernet (1000Mbps).
The quality of HSYV-5E dedicated cable is one of the key factors that determine the bandwidth of the LAN. Some manufacturers wrap the wire pairs used in Category 3 or Category 4 UTP cables in Category 5 UTP cables. This method is difficult for ordinary users to identify. This so-called "Category 5 UTP" cannot achieve 100Mbps data transfer rates, it is 10Mbps or 16Mbps. A simple identification method is to use a twisted pair to connect two 100Mbps devices (network card to network card or network card to HUB), and use the monitor detection tool that comes with Windows 95/98 to monitor their data transmission rate during communication.
Extended knowledge:
Category 5e cable refers to Category 5e unshielded twisted pair (UTP —Unshielded Twisted Pair) and shielded twisted pair (STP—Shielded Twisted Pair), which are upgraded versions of Category 5 lines.
Category 5e unshielded twisted pair cable is a cable that appears after improving some of the performance of the existing Category 5 shielded twisted pair cable. Many performance parameters, such as near-end crosstalk, attenuation crosstalk ratio, return Wave loss, etc. have improved, but its transmission bandwidth is still 100MHz.
The logo of Category 5 line is "CAT5", with a bandwidth of 100M, and is suitable for networks below 100M; the logo of Category 5e cable is "CAT5E", with a bandwidth of 155M, which is a mainstream product; the logo of Category 6 line It is "CAT6" with a bandwidth of 250M. It is used to set up Gigabit network and is the future development trend.
The Category 5e twisted pair uses 4 winding pairs and 1 tensile wire. The colors of the wire pairs are exactly the same as the Category 5 twisted pair, which are white-orange, orange, white-green, blue, White blue, green, white brown and brown. The bare copper wire diameter is 0.51mm (wire gauge is 24AWG), the insulated wire diameter is 0.92mm, and the UTP cable diameter is 5mm.
Category 5e network cables are used in 100M networks. Category 5e has many specifications. Generally, oxygen-free copper network cables will be selected for important comprehensive wiring projects. Oxygen-free copper has small resistance and long transmission distance. Transmission is stable.
The difference between Category 5e indoor network cables and outdoor network cables is that outdoor network cables have double-layer wire sheaths. In order to adapt to the changing environment of outdoor wiring, the outer layer is a layer of PE black water-blocking skin, and there is a layer of PE black water-blocking skin inside. Layer PVC waterproof layer. The outer thread is thick, waterproof and sun-proof, tensile and compressive, wear-resistant and thick, effectively preventing internal water from entering.
The difference between Category 5e unshielded network cables and shielded network cables is that shielded network cables have a shielding layer that can resist external interference and maintain normal signal transmission.
