hsyu5e is a Category 5e twisted pair, which has the characteristics of small attenuation and less crosstalk, and has higher attenuation to crosstalk ratio (ACR) and signal to noise ratio (signal to noise ratio), smaller The delay difference is greatly improved, and the performance is greatly improved. The transmission frequency of hsyu5e is as high as 100MHz. It is a Gigabit network cable and can be used in Gigabit networks. The twisting degree of the wire pairs in hsyv5e is relatively dense, so the signal transmission is fast, the quality is better, and the durability is better.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
When connecting to a local area network, the network cable is an indispensable material, and its selection is also directly related to the network speed. With people's continuous pursuit of high Internet speeds, Category 5, Category 5e, Category 6, Category 7 lines, etc. are now available on the market to meet the needs of different users. What kind of network cable is hsyu5e? Is hsyv5e a Gigabit network cable? How to distinguish between 100M network cable and Gigabit network cable? Let’s take a look below.
hsyu5e is Category 5e twisted pair. Category 5e twisted pair has the characteristics of small attenuation and less crosstalk, and has higher attenuation to crosstalk ratio (ACR) and signal to noise ratio (signal to noise ratio), smaller delay difference, and greatly improved performance. improve.
In hsyv5e, hsyv represents the structure of the line, 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 the hsyv5e center line pair The twist degree is denser, the signal transmission is faster, the quality is better, and the durability is better.
"Category 5e" refers to: Category 5e unshielded twisted pair (UTP-Unshielded Twisted Pair) unshielded twisted pair cable is composed of multiple pairs Consisting of stranded wires and a plastic sheath. Category 5 refers to the transmission frequency of twisted pair cables according to the International Electrical Industry Association as 100MHz (supports duplex applications). Category 5e unshielded twisted pair is a cable that has improved some of the performance of the existing Category 5 shielded twisted pair. Many performance parameters, such as near-end crosstalk, attenuation to crosstalk ratio, return loss, etc., have changed. Improved, but its transmission bandwidth is still 100MHz.
Unshielded Category 5e twisted pair also uses 4 winding pairs and 1 rip cord. The color of the wire pairs is exactly the same as that of Category 5 twisted pair, which are white (orange) / Orange, White (Green) / Green, White (Blue) / Blue, White (Brown) / Brown. The nominal bare copper (BC) wire diameter is 0.51mm (wire gauge is 24AWG), the insulated wire diameter is about 0.9mm, and the UTP cable diameter is generally 5mm.
How to distinguish between 100M network cable and Gigabit network cable
1. Look at the outer sheath of the network cable
On the outer sheath of the network cable, manufacturers usually print the Internet cable Types, such as CAT5, CAT5, etc., have different meanings. CAT5 represents a Category 5 cable, which is a 100M network cable, while CAT6 represents a Gigabit network cable, and CAT7 represents a 10Gb network cable.
2. Use equipment to identify
It is difficult for us to identify aging or improperly installed network cables from the outside. In this case, we can use the signal lights of some network devices to judge.
3. Judgment by computer network card information
We can also judge from the computer’s network card. If the network card and router both support 1000M, then they After the connection is completed, the signal light of the network card will turn on. If one of the computers or routers does not support Gigabit, it is impossible to determine.
4. Measuring wire diameter method
Since this method is more professional and requires the use of specific tools for measurement, the accuracy of the distinction is not ensured. It is recommended that professional operators use vernier calipers. Measurement.
5. Look at the wiring method
Generally speaking, when wiring a 100M network cable, you only need to connect 4 network cables, while when connecting a Gigabit network cable, you need to ground it, and these 8 All wires must be connected.
