The Renkforce RF-3684874 network extension system enables Ethernet connectivity over distances of up to 300 meters using 2-wire technology, significantly extending the standard Ethernet limit of 100 meters. This system achieves data transfer speeds of up to 200 Mbit/s and features Power over Ethernet functionality, allowing both network signals and electrical power to be transmitted over the same 2-wire cable. The package includes two adapters that support plug-and-play installation without the need for IP address configuration or network setup. A master adapter can supply up to four slave adapters via a terminal block distributor, making it particularly suitable for IP camera installations and network expansions in locations without power outlets. The system maintains compatibility with various network cable standards, including CAT 5, CAT 5e, CAT 6, CAT 6e, and CAT 7 cables, as well as standard 2-wire cables. It features automatic Quality of Service for seamless network streaming and supports IEEE 802.3 af/at PoE standards for powering compatible devices such as Wi-Fi access points, IP intercoms, IP cameras, and VoIP phones. LED indicators provide clear status information for power, connection, and data traffic. Its compact design allows for installation in tight spaces, making this solution practical for extending network coverage in challenging environments where traditional Ethernet limits would otherwise require complex infrastructure upgrades.
