Phybridge NV-EC4 Media Converter - 100 Mbps Ethernet to Coax with PoE

The Phybridge NV-EC4 is a high-performance media converter designed to extend Ethernet networks over coaxial cable. It enables reliable 100 Mbps Fast Ethernet connectivity over distances up to 610 meters (2,000 feet), making it ideal for upgrading legacy coax infrastructures without rewiring. The device supports Power over Ethernet (PoE/PoE+) and can be powered directly from a PoE switch or an optional external power adapter.

Advantages

Leverage existing coaxial cabling to deploy modern IP devices such as security cameras, access points, and VoIP phones. The NV-EC4 eliminates the need for costly new cable runs, reduces installation time, and provides a cost-effective migration path from analog to digital systems. Its compact external form factor allows flexible mounting on walls or desktops.

Suitable for

• Extending Ethernet networks over legacy coax in commercial buildings, campuses, and industrial sites
• Connecting IP cameras, wireless access points, and other PoE devices in remote locations
• Upgrading analog CCTV systems to IP without replacing cabling
