With this adapter, modern high-speed data communication networks can be established even in buildings without structured network cabling. The range extender utilizes the existing CAT. 5e, CAT. 6, or 2-wire telephone lines in the building for data transmission. This range extender allows twisted telephone lines to be used for high-performance data communication. This is particularly advantageous when WLAN or powerline solutions reach their limits due to building conditions. Depending on the technical specifications, transmission rates of up to 100 Mbit/s can be achieved over a cable length of up to 500 meters. This adapter is used when modern IP cameras need to be installed on an existing 2-wire line or CAT. 5e/6 line. Power supply on one side is sufficient. The converters support PoE (IEEE 802.3at) and also transmit power over the 2-wire line. This means one converter can supply power to the other converter(s). Each converter also has a fully functional PoE LAN port available. This means that IP cameras can also be powered. Special feature: with PoE function.
