Hardened 10/100BASE-TX PoL™/PoE Ethernet Extender over Coaxial Cable

Power over Link up to 1.8 km (5905 ft.) by coaxial cable
Maximum 30 Watts power with 100Mbps bandwidth
LEDs display transmission rate and PoE wattage




The ED3638 Hardened Ethernet Extender utilizes EtherWAN’s exclusive Power over Link (PoL) technology to deliver both PoE power and Ethernet communications over a single legacy coaxial cable. The ED3638 PoL solution is comprised of one transmitter and one receiver working together to provide reliable communications and power to remote PoE Powered Devices such as IP cameras, wireless access points, emergency intercoms, or VoIP phones.

With just the transmitter connected to power, the ED3638 provides a maximum of 30 watts of power and a bandwidth of 100Mbps to the ED3638 receiver, at distances up to 400 meters. Under this setup, transmission over longer distances can be achieved with lower data and power throughput — up to 1800 meters at a data rate of 15Mbps and 4 watts of power. However, for applications that require even longer distances, the ED3638 can be connected to power at both the transmitter and the receiver unit, increasing the transmission distance to a remarkable 2400 meters, with a data rate of 4Mbps and a full 30 watts. The current data transmission rate and power sourcing equipment output is displayed by LED indicators.

The ED3638 is highly resistant to electromagnetic interference, shock, and vibration, ensuring connection reliability even in harsh environments.
