Patton’s EHA2172 breaks distance and speed barriers with up to 50 Mbps full-duplex and distances of up to 5,500 feet (1,700m) over already existing infrastructure cabling.

The Model EHA2172 simplifies network extension by utilizing twisted-pair infrastructure previously used for legacy systems such as serial circult TTL, RS-232 and RS-422/485, phone lines, or even alarm circuits to be used for extending or connecting Ethernet devices together. With a pair of EHA2172s (or combined with a Patton 2172 or 2172R), a user can extend network connections up to 5,500 feet. Reusing already existing infrastructure for Ethernet Networking eliminates purchasing expensive fiber and Cat5E or greater cabling. Most important, it completely eliminates the hassle, expense, and downtime of cable installations. The EHA2172 operates in rugged environments and is NEMA3 certified. The EHA2172’s steel case can be conveniently mounted on a wall or pole.


The Model EHA2172 auto-rate Ethernet Extenders are ideal for delivering network connections to remote offices and Ethernet enabled devices that are beyond the 328-foot (100-meter) distance limit of Ethernet. The 50 Mbps throughput eliminates bandwidth concerns previously experienced with other copper wired transmission technologies. By utilizing existing voice grade copper pairs the expense and hassle of installing low capacitance or fiber cable is no longer required.

  • Convert Analog or Digital to IP—Convert your Analog (POTS) or Digital (ISDN) circuits to IP for toll quality VoIP services
