Description

Signal transmission and power supply connector of network system {RJ-45 CONNECTOR HAVING FUNCTION OF SIGNAL TRANSMISSION AND POWER SUPPLY IN NETWORK SYSTEM}

The present invention relates to a signal transmission and a power supply connector of a network system, and more particularly, a network capable of simultaneously transmitting and feeding signals by using an RJ-45 connector applied to an Ethernet. A signal transmission and power supply connector of a system.

In general, connecting a computer to a computer is called a network. A brief look at the hardware that makes up a network system includes NICs, cables, hubs, repeaters, routers, bridges, and DSUs.

In this case, the NIC is called a LAN card or a network interface card (NIC), and is responsible for receiving and transmitting data from a computer. In addition, the LAN card has an Ethernet processor to control the data transmission by receiving a signal from the CPU, the LAN card has three ports depending on the connector to connect. That is, there are ports for RJ-45 connectors similar to modem ports, ports for connecting transceivers (AUI), and ports for connecting coaxial cables (BNC).

The cable is connected to the LAN card, and different cables are used depending on the purpose of use, distance, and network equipment. The most common ones are UTP (Unshielded Twisted Pair) and Coaxial Cable (BNC). Although not yet common, optical cables are also used.

The hub is a network device for connecting using UTP, and can be connected to another network device such as another hub or router. Hubs can be divided into 4, 8, 12, 16, and 24 port hubs according to the number of ports.Dummy hubs act as simple relays depending on their functions. And additional switching hubs.

The repeater is a device for amplifying a signal that is attenuated when a network line is long, and the router is a network device that serves to connect networks using different OSs and protocols to each other.

The bridge serves to separate the network, which is used when the network connected to the bridge knows how to configure, which OS to use, and which protocol to use. It searches for the method and connects it properly.

The DSU stands for Digital Service Unit and serves as a modem for a telephone line. It is generally used in leased lines that do not need to convert digital signals and analog signals, and is generally used when there is a leased line for connecting remote locations in the region.
