The NV-ECLK-PLS-1X-AB EoC Adapter from NVT is a single endpoint solution that enables the transmission of 100 Mb/s full-duplex PoE over a single long run coaxial cable. It extends PoE over Coax to distances of 6000' when paired with a compatible device like the EC-Base Extender (available separately). This unit can be powered locally with an optional adapter or via a PoE switch. It features 802.1x port-based authentication, along with power negotiation for mode A first, then mode B for non-compliant 802.3af/at devices.
