AZIPPOE300
AZIPPOE300 is a PoE, extender-over-coax solution. By using RF technology, it can extend the transmission distance of power and 100Mbps Ethernet, data-over-legacy, coaxial cable to save re-cabling costs. This is the first, “true,” PoE extender (not repeater) technology to achieve greater distances beyond the standards and the flexibility of using existing cable plants.
