In many cases, the connection is ultimately between active components such as switches, which recognize the connected devices and switch automatically. However, crossover cables hardly play a role in Ethernet connections. On one end, this cable therefore requires an assignment according to T568A and on the other end one according to T568A. One pair of wires is responsible for receiving data and the other for sending data. These cores are then assigned as follows:Īs soon as two devices of the same type communicate with each other, for example between a computer and a computer, a crossover cable is always used. The eight cores of the cable are sorted in the desired assignment using an insertion aid and crimped in the connector housing. However, these are primarily found in telephone connection lines. Other standards such as RJ11 are also used in telecommunications. The RJ45 connectors are used for data transmission in networks. The term “ISDN connector” is also frequently used for the eight-pole modular connectors. 15,99 (0,32 /Count) Consegna GRATUITA ven, 15 set sul tuo primo ordine idoneo. Since Ethernet cables have an RJ45 connector on each end, Ethernet cables are sometimes also called RJ45 cables. It looks similar to a telephone jack, but is slightly wider. In the case of Ethernet connectors, therefore, all eight available contacts in the plug are used. Rugged RJ45 Modular Jack, IP67, 8P8C, with LEDs, on PCB with Standard RJ Receptacle, RoHS Compliant. UGREEN 50 Pezzi Connettore RJ45 Cat5e, Plug RJ45 8 Pin per Cavo Ethernet Cat5e Cat5 Gigabit Ethernet 1000Mbps, Compatibile con PC, Router, Switch. RJ45 is a type of connector commonly used for Ethernet networking. In any case, the designation for a connector concludes with the number of possible contact positions (P, for “Positions”) and the number of contacts actually fitted (C, for “Contacts”). For example, the “W” stands for “wall socket” or the “S” for an single connection. In some cases, there is also an addition that refers to mechanical properties. This is followed by two numbers that specify the type of plug. The categorization follows a certain scheme, which always begins with RJ (=Registered Jack). There are different versions of plugs and sockets in terms of shape and number of contacts. A few years later, they were standardized by the Federal Communications Commission (FCC). RJ connectors were introduced by Bell Laboratories (USA) in the 1970s.
