Ethernet Vertical phosphor bronze gold plating over nickel Jack RJ45 Female Socket
RJ45 cable plug also known as crystal head, a total of eight cores made, widely used in LOCAL area network and ADSL broadband Internet users network equipment between the network cable (known as the five line or twisted-pair line) connection. In specific applications, there are two connection methods (sequence) for RJ45 plugs and network cables, respectively called T568A sequence and T568B sequence.
The identification method of RJ45 type cable plug pin number is: hold the plug, there are 8 small gold-plated piece one end up, one end of the rectangular mouth into the network cable is down, at the same time there will be no slender plastic pin that facing your eyes, from the left of the first small gold-plated piece is the first foot, the second foot... Foot 8.
This connection method is used for network equipment to cross-connect the occasion, the so-called crossover refers to one end of the network cable and the other end of the RJ45 cable plug connection method is different, one end according to T568A line sequence connection, the other end according to T568B line sequence connection, that is, several network cables at the other end is the first to do the crossover before connecting to the RJ45 plug up.
The RJ45 interface is usually used for data transmission, and the most common application is the network interface.
The RJ45 is a type of various connectors; There are two different methods of RJ45 head according to the line, one is orange and white, orange, green and white, blue, blue and white, green, brown and white, brown; The other is green-white, green, orange-white, blue, blue-white, orange, brown-white, brown; Therefore, there are two kinds of lines using RJ45 connectors: straight line, cross line.
10 100Base TX RJ45 ports Are common Ethernet ports that support 10 mbit/s and 100 MBIT/s adaptive network connection speeds. Common RJ45 ports are DTE ports for Ethernet nics and routers and DCE ports for switches. DTE can be called "data terminal equipment", DCE can be called "data communication equipment". In a sense, DTE devices are called "active communication devices" and DCE devices are called "passive communication devices". When two devices of the same type communicate using an RJ45 connection, a crossover connection must be used.
