RJ45 Interface Comprehensive Analysis—A Professional Guide from Principle to Selection

The RJ45 interface, as a standard configuration for modern network connections, is undeniably important. This 8P8C connector uses four pairs of twisted-pair wires to transmit data, with each pair using a specific twist rate to cancel electromagnetic interference. Professional RJ45 interface manufacturers ensure signal transmission stability by optimizing contact plating (usually using a 50μ gold-plating process) and insulating materials.

Selection criteria and supply chain strategy for RJ45 Ethernet connectors

In network card manufacturing, the performance of the RJ45 Ethernet connector directly affects network transmission quality. Enterprises need to select matching RJ45 jack specifications according to the application scenario of the network card, such as: Bandwidth support: Cat5e (1Gbps), Cat6 (10Gbps@55m), Cat6A (10Gbps@100m), etc. Different levels of RJ45 Ethernet connectors must be consistent with the target rate of the network card. PoE power supply capability: If the network card supports PoE (802.3af/at/bt), the RJ45 Ethernet connector must use a high-current carrying design (such as gold-plated contacts) to avoid overheating and performance degradation.
