The Renkforce RF-2982884 network extension kit enables the establishment of high-speed data communication networks in buildings without structured network cabling. It utilizes existing CAT-5e, CAT-6, or two-wire telephone lines for data transmission, achieving speeds of up to 100 Mbit/s over cables with a maximum length of 400 meters. This adapter is particularly advantageous when Wi-Fi or powerline solutions are limited by building conditions, allowing the connection of modern IP devices such as IP cameras to existing cabling. The kit includes two network extenders, each powered by a 5V USB port from a computer or laptop, eliminating the need for additional power supplies. Connection terminals are integrated into the two-wire ports and power supply to ensure secure cable attachment and prevent accidental disconnection, which is beneficial in complex installations. The extenders feature a hole spacing of 90 mm for mounting and can be used up to five times in a network configuration, with one unit serving as the starting point and up to four as extensions. This solution supports reliable data communication without Power-over-Ethernet functionality and focuses on durability and easy integration into existing infrastructures.
