Altronix EBRIDGE200WPMH 2-Port Ethernet over coax/CAT5e Transc

Altronix EBRIDGE200WPMH EoC 2-Port Long-Range Ethernet Transceiver

Overview

The Altronix EBRIDGE200WPMH is an outdoor Ethernet-over-Coax (EoC) transceiver designed to extend PoE-powered network connectivity over existing coaxial infrastructure to distances up to 300 meters. This 2-port unit functions as a receiver-side transceiver and passes Power over Ethernet (PoE), PoE+, and Hi-PoE up to 60W, enabling integrators to retrofit legacy coax runs with modern IP security systems without rewiring. Housed in a weather-resistant outdoor enclosure with three wiring inlets and glands, the EBRIDGE200WPMH supports mixed analog and digital deployments where coax infrastructure already exists on-site.

Key Features

• Extended Range: Reaches devices up to 300 meters away using existing coaxial cabling
• PoE Power Passthrough: Supports PoE, PoE+, and Hi-PoE with up to 60W budget from the compatible receiver unit
• 2-Port Ethernet: Dual Ethernet ports for flexible network device connectivity
• Outdoor Rated: Sealed enclosure with three wiring inlets fitted with cable glands for field installation in outdoor environments
• EoC Technology: Leverages existing coaxial runs, eliminating the need for new twisted-pair cabling in retrofit applications
• Receiver-Dependent Operation: Requires compatible Altronix receiver unit to function; transceiver operates as part of complete EoC link

Integration & Compatibility

The EBRIDGE200WPMH is purpose-built for integrators managing mixed-infrastructure environments. This receiver-side transceiver works in tandem with a compatible Altronix transmitter unit to form a complete EoC bridge. The 60W PoE+ Hi-PoE budget accommodates power-hungry PTZ cameras, access control readers, and other outdoor security endpoints. Three glandable inlets provide flexible entry points for coax feed-in, DC supply, and Ethernet output runs, simplifying field termination and reducing installation labor on retrofit projects. The unit's outdoor rating and sealed construction make it suitable for permanent exterior mounting on poles, walls, or equipment racks.

Field Deployment Considerations

System integrators should verify coaxial cable condition and impedance before deployment, as EoC performance depends on signal integrity over the run. The 300-meter specification applies under standard conditions; actual range may vary based on cable quality, age, and environmental factors. Pair the EBRIDGE200WPMH with the matching Altronix transmitter and ensure PoE supply at the transmitter location meets or exceeds the power budget of connected devices. This architecture centralizes power and network management at the transmitter end while extending connectivity to distant outdoor locations, reducing the need for remote power supplies or long Ethernet runs.

Karl Wilson

I've specified the EBRIDGE200WPMH on several campus and industrial retrofit projects where coaxial backbone runs already existed. The transceiver's ability to carry full PoE+ and Hi-PoE over 300 meters of coax eliminates expensive rewiring and reduces project timelines significantly. The outdoor housing and glandable inlets make field termination straightforward, and the 60W power budget is sufficient for most IP cameras and access devices we deploy at the edge.

Technical Highlights:

• 300-Meter Reach: EoC architecture extends Ethernet and power over existing coaxial infrastructure without new cabling
• 60W PoE Budget: Passes PoE, PoE+, and Hi-PoE from the compatible receiver, supporting power-intensive outdoor endpoints
• Dual Ethernet Ports: Two ports allow for daisy-chaining or flexible endpoint connectivity at the remote location
• Receiver-Dependent Design: Operates as the receiving end of an EoC link; transmitter compatibility is essential

Deployment Considerations:

• Verify coaxial cable type, impedance, and condition before installation; older or damaged runs may reduce effective range or signal quality
• Confirm compatible transmitter unit is in stock and sized for your network topology
• Plan power budget carefully at the transmitter location to support all devices on the remote end
• Use the three glandable inlets for organized field termination; seal unused inlets to maintain outdoor rating

The EBRIDGE200WPMH is a practical choice for integrators managing legacy infrastructure upgrades. It shifts the complexity burden from physical rewiring to system planning and configuration, making it a reliable option for retrofit security deployments in outdoor and campus environments where coax already runs to remote locations.
