RJ45liittimen

RJ45liitin is the Finnish term for an RJ45 connector. It is a standardized connector commonly used for terminating Ethernet cables. These connectors are typically found at the ends of network cables, allowing them to be plugged into network interfaces on computers, routers, switches, and other network devices. The RJ45 connector is an 8-position, 8-contact (8P8C) modular connector. This means it has eight physical positions for wires and eight electrical contacts. The arrangement of these contacts and the order in which the wires are terminated are crucial for proper network communication. There are two primary wiring standards for RJ45 connectors: T568A and T568B. While both standards use the same pinout for data transmission, the order of some colored wires differs. A straight-through cable uses the same wiring standard at both ends (e.g., T568B on both ends), while a crossover cable uses different standards (e.g., T568A on one end and T568B on the other). RJ45 connectors are an integral part of modern wired local area networks (LANs), providing a reliable and standardized method for physical network connections.
