What is the communication distance of twisted pair cable?

The default communication distance of twisted pair is 100m; if you want to increase the transmission distance, you can install a repeater between two sections of twisted pair. Up to 4 repeaters can be installed to connect 5 networks. segment, the maximum transmission communication distance can reach 500m.

The maximum transmission distance of twisted pair is 100m. If you want to increase the transmission distance, a repeater can be installed between two twisted pairs, and up to 4 repeaters can be installed. If 4 repeaters are installed to connect 5 network segments, the maximum transmission distance can reach 500m.

Common twisted pair cables include Category 3 lines, Category 5 lines and Category 5e lines, as well as the latest Category 6 lines. The former has a thin wire diameter and the latter has a thick wire diameter. The models are as follows:

1) Category 1 line: mainly used to transmit voice (Class 1 standard was mainly used in telephone cables before the early 1980s), which is different from data transmission.

2) Category II line: The transmission frequency is 1MHZ, used for voice transmission and data transmission with a maximum transmission rate of 4Mbps. It is common in old token networks that use the 4MBPS standard token passing protocol.

3) Category III cable: refers to the cable currently specified in the ANSI and EIA/TIA568 standards. The transmission frequency of this cable is 16MHz. It is used for voice transmission and data transmission with a maximum transmission rate of 10Mbps. It is mainly used for 10BASE --T.

4) Category 4 cable: The transmission frequency of this type of cable is 20MHz, used for voice transmission and data transmission with a maximum transmission rate of 16Mbps. It is mainly used for token-based LAN and 10BASE-T/100BASE-T.

5) Category 5 cable: This type of cable has increased winding density and is coated with a high-quality insulating material. The transmission rate is 100MHz. It is used for voice transmission and data transmission with a maximum transmission rate of 10Mbps. It is mainly used for voice transmission and data transmission with a maximum transmission rate of 10Mbps. For use in 100BASE-T and 10BASE-T networks. This is the most commonly used Ethernet cables.

6) Category 5e cable: Category 5e has small attenuation, less crosstalk, higher attenuation to crosstalk ratio (ACR) and signal-to-noise ratio (Structural Return Loss), smaller time Latency is poor and performance is greatly improved. Category 5e cables are mainly used for Gigabit Ethernet (1000Mbps).

7) Category 6 cable: The transmission frequency of this type of cable is 1MHz ~ 250MHz. The Category 6 wiring system should have a large margin in the comprehensive attenuation crosstalk ratio (PS-ACR) at 200MHz. It provides 2 Times the bandwidth of Category 5e.
