The speed of Category 5 network cable can reach 100M. Category 5 network cable is a twisted pair cable used in computer networks, labeled CAT5. The broadband transmission speed is 100Mbit, and it is more suitable for network transmission below 100Mbit. Category 5 lines were born with 100Mbps Fast Ethernet, but with the development of network technology, the physical layer transmission protocol 1000Base-T based on Category 5 lines has enabled Category 5 lines to also have the transmission capability of Gigabit Ethernet. The technology achieves a smooth transition from 100M to 1000M while retaining the original cables.

What is Category 5 network cable

Category 5 cable, referred to as Cat.5, is a twisted pair cable used in computer networks , is also a multimedia wire used in information communication services such as data and voice. It is widely used in Ethernet and broadband access projects. Its quality is directly related to the transmission quality of information communication. Due to the development of optical fiber and communication technology, the impact of twisted pairs on communication quality is gradually decreasing.

Category 5 network cables will be marked CAT5. The broadband transmission speed is 100 MB, which is more suitable for network transmission below 100 MB.

Development and Application

Category 5 lines were born with 100Mbps Fast Ethernet, but with With the development of network technology, the physical layer transmission protocol 1000Base-T based on Category 5 lines enables Category 5 lines to also have the transmission capability of Gigabit Ethernet (1,000,000,000 bit/s). This technology can retain the original cables. Under this circumstance, a smooth transition from 100M to 1000M is achieved. Therefore, after the devices at both ends automatically negotiate, the Category 5 line can bear Ethernet at different rates under the technologies of 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet) at a working frequency of 100MHz. transmission medium. To ensure transmission quality, the transmission distance of Category 5 lines is generally within 100 meters.

More applications of Category 5 cables:

Category 5 cables, as 8-core copper cables with good performance, can naturally play a role in signal transmission other than Ethernet, such as carrying voice and video. . In some cases, Category 5 can carry multiple traditional phone lines on a single cable. There are several options for transmitting analog or digital video over cable. HDBaseT (10.2 Gb/s) is one such solution.

Power over Ethernet (POE)

POE (Power Over Ethernet) refers to the situation where no changes are made to the existing Ethernet Cat.5 cabling infrastructure While transmitting data signals for some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.), it can also provide DC power supply technology for such equipment. POE technology can ensure the security of existing structured cabling while ensuring the normal operation of existing networks and minimizing costs. POE has gathered the wisdom of many experts, and it has also allowed Category 5 wires, which are somewhat old wire gauges, to continue to exert their vitality and potential.

What is the difference between Category 5 and Category 5e?

1. Category 5 network cables will be marked CAT5, and the broadband transmission speed is 100 ; The Category 5e network cable logo is CAT5E, and the transmission speed of broadband is 155M. This kind of transmission can drive Gigabit network and is a common network cable now.

#2. The transmission speed of Category 5 network cable is not as good as that of Category 5e signal, because Category 5 network cable only uses two pairs of wires for transmission, and Category 5e network cable uses For four-pair transmission, the transmission distance of Category 5 network cable can only be within 100 meters, so it is not suitable for communication applications, while Category 5e can reach 300 meters. Now our routers and gateways basically use Category 5e. Similar network cable.

3. The outer layer of Category 5e network cable is much better than that of Category 5 network cable, so it has a longer service life. There is no need to shield the crosstalk of the network cable, so the return loss is relatively small, the time difference delay is small, and the transmission high speed.
