The difference between RJ45 connectors and other connectors!

Different applications RJ45 connectors are usually connected to both ends of the network cable to connect to computer and other network equipment, while RJ11 connectors are connected to ADSL, voice cable at both ends to connect a telephone or modem. RJ45 connector and RJ11 connector in the size, wiring standards and scope of application are different, the two do not have interoperability, in use should pay particular attention to. RJ11 connector the four-core crystal head used in the phone line is the RJ11 connector. It is similar to the RJ45 connector, but only has four pins. It is a connector developed by Western Electronics, used to connect a telephone to a modem. Note that RJ11 usually refers to a 6-pin modular jack or plug, but only 4 pins are used, in addition, RJ11 is also used for the 4-pin version of the modular plug-in.

The difference between RJ45 connectors and RJ11 connectors is the structural difference. An RJ45 connector is a connector with eight grooves and eight contacts (8P8C) , whereas an RJ11 connector typically has only six grooves and four contacts (6P4C) , thus, the RJ45 connector is larger than the RJ11 connector. RJ11 connectors can usually be inserted into an RJ45 interface, and not vice versa, but it is highly recommended that you do not use an RJ11 connector for an RJ45 interface. Different wire sequence standards due to the different structure of RJ45 connector and RJ11 connector, the wire sequence standards are also different. RJ11 connectors generally have only 6 grooves and 4 contacts (6P4C) , and the wire sequence is fixed. RJ45 connectors are wired with two sequence standards: T-568a and T-568B. Through the adoption of different standards, the final production of the wire has a straight-through and cross-type two. Now all the network cable production are using 568B,
