What brand of network cable should I use for hotel rooms? What type of network cable do you use?

1) Category 5 cable: This kind of cable is covered with high-quality insulating material, and the transmission rate is 100MHz, which is used for voice transmission and data transmission. The highest transmission rate is 10Mbps, which is mainly used in 100BASE-T and 100 Base-T networks. This is the most commonly used Ethernet cable.

2) Super Category 5 line: Super Category 5 line has small attenuation, less crosstalk, higher attenuation crosstalk ratio (ACR) and structural return loss, smaller time delay and greatly improved performance. Category 5 cables are mainly used for Gigabit Ethernet (1000Mbps).

3) Category 6 cable: the transmission frequency of this cable is 1 MHz ~ 250 MHz. The PS-ACR of Category 6 cabling system should have a large margin at 200MHz, which can provide 2 times the bandwidth of Category 5. The transmission performance of Category 6 cabling is much higher than Category 5 standard, and it is most suitable for applications with transmission rate higher than 1Gbps. An important difference between Class 6 and Class 5 is that it improves the performance of crosstalk and return loss, which is very important for the new generation of full-duplex high-speed network applications. The basic link model is cancelled in the six standards, and the wiring standard adopts star topology. The required wiring distance is: the permanent link length cannot exceed 90m, and the channel length cannot exceed1200mm.

To put it simply, there is no difference between the six categories and the five categories, but the bandwidth is slightly different, only the six categories and the five categories of modules are different! The method and size of crystal head are the same as those of five types!

In addition to the traditional voice system still using three types of twisted pairs, network wiring basically uses more than five or six types of unshielded twisted pairs. Although the five types of unshielded twisted pair can still support 1000Base-T, it has gradually faded out of the wiring market because its price is almost the same as that of the super five types of unshielded twisted pair.

Although category 6 unshielded twisted pair is expensive, it is becoming the new favorite of integrated wiring due to its excellent compatibility with category 5 wiring system and excellent support for1000base-T. As a brand-new wiring system, category 7 shielded twisted pair has excellent performance, but it is expensive. The construction is complicated and there are few optional products, so it is rarely used in wiring engineering.

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.
