The NV-ECLK-BSE Extender is a powerful Ethernet over Coax (EoC) network extender designed to enhance the downlink ports of standard Ethernet switches by extending 10/100 Mbps symmetrical full-duplex Ethernet and Power over Ethernet (PoE) across existing coaxial cable infrastructure. When paired with CLEER Family adapters, this solution enables IP IoT devices such as IP cameras, access control, and VoIP phones to connect reliably over coax with extended reach up to 4,000 feet (1,220 meters), significantly exceeding the limitations of traditional Ethernet cabling. The NV-ECLK-BSE Extender allows organizations to leverage their installed coaxial cabling plant, minimizing costs, installation time, and environmental impact by avoiding costly cable replacements. With a compact design weighing only 3.81 oz and a low power consumption of 1W, it efficiently supports network transformations while maintaining optimal performance. The extender is fully TAA compliant, making it suitable for government and commercial installations requiring long-distance PoE connectivity over legacy infrastructure.
