Types and uses of twisted pair and connector products

　　The types and uses of twisted pair and connector products are as follows:

　　Types of twisted pair

　　Twisted pair is a common tranSMission medium that can be divided into various types according to its transmission performance and purpose.

　　A class of lines (CAT1):

　　Purpose: Mainly used for voice transmission, especially for telephone cables before the early 1980s.

　　Features: Low frequency bandwidth, not suitable for data transmission.

　　Class II line (CAT2):

　　Purpose: For voice transmission and data transmission with a maximum transmission rate of 4Mbps.

　　Features: Common in legacy token networks that use the 4Mbps standard token transfer protocol.

　　Three types of lines (CAT3):

　　Purpose: Mainly used for 10BASE-T Ethernet and voice transmission.

　　Features: The transmission frequency is 16MHz, and the maximum transmission rate is 10Mbps.

　　Four types of lines (CAT4):

　　Purpose: For voice transmission and data transmission with a maximum transmission rate of 16Mbps, mainly for token-based local area networks.

　　Features: The transmission frequency is 20MHz.

　　Category 5 (CAT5):

　　Purpose: Used for voice transmission and data transmission with a maximum transmission rate of 100Mbps, it is a commonly used Ethernet cable.

　　Features: Increased winding density, high-quality insulating material, transmission frequency of 100 MHz.

　　Super Category 5 line (CAT5e):

　　Purpose: Mainly used for Gigabit Ethernet (1000Mbps).

　　Features: It has the advantages of small attenuation and less crosstalk, and its performance is better than that of Category 5 wires.

　　Category 6 (CAT6):

　　Purpose: Suitable for applications with transmission rates higher than 1Gbps.

　　Features: The transmission frequency is 1MHz to 250MHz, providing twice the bandwidth of Super Category 5, improving crosstalk and return loss performance.

　　Super Category 6 (CAT6A):

　　Purpose: The transmission bandwidth is between Category 6 and Category 7, suitable for high-speed network applications.

　　Features: The transmission frequency is 500MHz, and the transmission speed is 10Gbps.

　　Category 7 lines (CAT7):

　　Purpose: Adapt to the application and development of 10 Gigabit Ethernet technology.

　　Features: Shielded twisted pair, transmission frequency up to at least 500MHz, transmission rate up to 10Gbps.

　　Second, the product types of twisted pair connectors

　　Twisted pair connector products mainly include various types of joints and connectors for connecting twisted pairs or interfacing with other devices.

　　Straight-through twisted pair connector:

　　Purpose: Simply insert two twisted pair wires into the connector to complete the connection.

　　Features: The signal loss is large, making it unsuitable for long-distance transmission.

　　Shielded twisted pair connector:

　　Purpose: It is used to reduce signal interference and improve signal transmission quality.

　　Features: Complex structure requires professional installation.

　　Ordinary twisted pair connector:

　　Purpose: Between the through type and the shielded type, suitable for general occasions.

　　Features: Simple structure, better signal transmission quality than through-type connectors.

　　RJ45 connector:

　　Purpose: Widely used for Ethernet connection, such as network interface cards, switches, routers and other devices.

　　Features: With 8 pins, it supports high-speed data transmission and a variety of network protocols.

　　RJ11 connector:

　　Purpose: Mainly used for telephone line connection, such as the interface between telephones and telephone lines.

　　Features: With 4 or 6 pins, it is suitable for low-speed voice transmission.

　　Third, the use of twisted pair and connector products

　　Twisted pair and connector products are widely used in various network environments, including local area networks (LANs), wide area networks (WANs), data centers, home networks, etc. Their main uses include data transmission, voice communication, video transmission, etc. In addition, twisted pair is also often used in monitoring systems for signal transmission due to its strong anti-interference ability, long transmission distance, easy wiring, and low price.

　　Overall, there are various types and uses of twisted pair and connector products, and selecting the right twisted pair and connector products is essential to ensure network performance and stability.
