Modular Connectors - Jacks are standardized interface components used in electronic devices, primarily for transmitting audio, video, or other forms of data signals. This socket is usually composed of metal contacts, insulation materials, and a housing, and the design principle is based on reliable electrical connections between physical contacts and external device plugs. Modular connectors - sockets have the characteristics of easy installation, disassembly, and replacement, which can meet the connection needs of different application scenarios. Its characteristics include high reliability, durability, and extensive compatibility.

Modular Connectors - Jacks are widely used in various fields such as communication equipment, computers and their peripherals, consumer electronics, car audio systems, medical equipment, etc. In communication devices, such sockets are commonly used to connect telephone lines, network cables, etc., to achieve the transmission of voice and data; In the field of computer science, modular connectors and sockets can be used to connect keyboards, mice, and other peripherals, providing a stable signal transmission channel; In consumer electronics products such as televisions and audio systems, these sockets support the input and output of audio and video signals; In the automotive industry, modular connectors and sockets are used to build in car entertainment systems and enhance the driving experience; In medical equipment, these types of sockets can connect various monitoring instruments to ensure the accuracy of data transmission.

• 1. What is the purpose of modular jacks?

  The purpose of modular jacks is to connect devices to the network. Modular jacks are designed to provide a flexible and scalable solution to adapt to changing and diverse network needs. They usually have multiple free slots, allowing users to choose modules of different numbers, speeds and interface types to install according to specific needs, thus achieving a high degree of customizability and scalability.

• 2. What are the different types of RJ45 modular jacks?

  There are two main types of RJ45 modular jacks, namely DTE (data terminal equipment) type and DCE (digital communication equipment) type.
  The difference between these two types lies in the way they are connected to different devices.
  The DTE type is mainly used in Ethernet network cards, routers and other devices. When two DTE type devices use RJ45 interface connection for communication, they must be connected using a crossover cable. This is because the data sending and receiving pins of the DTE type interface cannot perform normal data communication if they are not cross-connected.
  The DCE type is usually used in devices such as switches. When connected to a DTE type device, the DCE type device can automatically negotiate with the other party. At this time, a straight-through line or a parallel line can be used for connection, depending on the automatic negotiation capability of the device.

• 3. What is the difference between RJ50 and RJ45 connectors?

  The main differences between RJ50 and RJ45 connectors are transmission rate, application scenarios, number of pins, line sequence, transmission distance, and anti-interference ability.
  Transmission rate and application scenarios:
  The transmission rate of the RJ50 interface is low, and it can usually only transmit voice and low-speed data signals. It is mainly used for telephone lines and low-speed network devices such as modems and routers.
  The transmission rate of the RJ45 interface is high, and it can transmit high-speed data signals. It is mainly used for Ethernet and high-speed network devices such as computers, switches and routers.
  Number of pins and line sequence:
  The RJ50 interface has 4 pins, and the line sequence is 1-2-3-4.
  The RJ45 interface has 8 pins, and the line sequence is 1-2-3-4-5-6-7-8.
  Transmission distance and anti-interference ability:
  The transmission distance of the RJ50 interface is short, and it can usually only be used within a few dozen meters. It h
