Ubiquiti F-POE-G2 Fiber-to-Ethernet PoE Media Converter
Overview
The Ubiquiti F-POE-G2 is a point-to-point fiber-to-Ethernet media converter that solves a critical deployment constraint: delivering both power and data to remote edge devices where standard copper PoE runs cannot reach. If your site has existing dark fiber or long-distance single-mode/multimode fiber already in place but cannot run separate electrical feeds to remote access points, surveillance cameras, or wireless equipment, the F-POE-G2 (often searched as F POE G2) eliminates that friction. The converter pair operates transparently — one unit at the central aggregation point injects power and Gigabit Ethernet data onto the fiber strand; the remote unit extracts both and presents them on standard copper RJ-45, requiring no configuration or management.
Key Features
- 1 Gbps Throughput Both Directions: Handles full-duplex Gigabit Ethernet, sufficient for concurrent IP camera feeds, wireless backhaul, and management traffic. Avoids the bandwidth bottleneck that limits older media converters in multi-device remote sites.
- Integrated Power Delivery Over Fiber: The central-side converter energizes the fiber link; the remote unit draws power directly from that link without requiring AC mains, generator, or separate DC feed at the far end. Drastically simplifies logistics in rural, rooftop, or distributed antenna system (DAS) deployments where electrical infrastructure is absent or cost-prohibitive.
- Pair Deployment Model: Always install as matched units—one at the hub (powered from mains or PoE), one at the remote edge (powered by fiber). This dual-unit approach is non-negotiable; a single F-POE-G2 will not function standalone.
- Fiber-Agnostic: Accepts standard single-mode or multimode fiber, accommodating existing cable plants without retermination. Choose fiber type based on distance and budget; the converter handles both transparently.
- Compact Form Factor: Weighs 1.150 lb and fits rack, wall-mount, or pole installations. Designed for outdoor and indoor environments typical of telecom and carrier infrastructure, allowing flexible placement near fiber patch panels or in MDF spaces.
- Passive Integration with UISP Networks: Bridges fiber and copper domains without requiring IP configuration, SNMP, or management interface. Standard UISP-based systems (access points, cameras, routers) connect to the copper port and operate as if locally attached.
Deployment Scenarios
The F-POE-G2 excels in campus networks, rural wireless deployments, and carrier-grade infrastructure where fiber runs already exceed standard PoE distance (100 meters copper limit). Typical use cases include feeding remote IP surveillance cameras, distributed wireless access points, or small routing nodes from a central fiber hub. In a campus scenario, run a fiber backbone between buildings; at each remote building, the F-POE-G2 converts fiber to local copper, powering and feeding a small managed PoE switch or directly connecting an access point. In carrier cell-site or DAS applications, the F-POE-G2 eliminates the need for backup generators or AC runs to remote antenna feeds, reducing site acquisition costs significantly. The converter pair also works well in temporary deployments—test a site with fiber; if permanent, leave the converters in place; if not, recover the equipment and fiber for redeployment elsewhere.
Network Integration & Compatibility
The F-POE-G2 is vendor-agnostic at the copper interface—any standard 1GbE device (cameras, routers, network video recorders, managed switches) will work. The converter transparently passes Ethernet frames and power without inspection or filtering. Ensure the central-side unit has adequate PoE input (the converter will draw 90W or more depending on remote device load); a PoE power budget calculator is critical for sizing your central infrastructure. Install the pair close to patch panels to minimize fiber-to-RJ45 transitions and reduce troubleshooting complexity. Test fiber continuity and polarity before energizing to avoid swapping TX/RX leads.

Frequently Asked Questions
Q: Do I need two F-POE-G2 units for a deployment?
A: Yes. The F-POE-G2 is designed as a pair. One converter sits at the central site (powered from AC or PoE), the other at the remote end (powered by the fiber link itself). A single unit will not function.
Q: What's the maximum distance the F-POE-G2 can span?
A: The evidence does not specify a distance limit. Standard single-mode fiber can span tens of kilometers; multimode is practical to 2 km. Contact the vendor or your integrator for specific distances based on your fiber type and termination quality.
Q: Can I use the F-POE-G2 with existing fiber already in my network?
A: Yes. The converter accepts standard single-mode or multimode fiber, so you can use existing cable plants without retermination. Confirm fiber polarity and continuity before deployment.
Q: Will the F-POE-G2 work with non-Ubiquiti devices on the copper side?
A: Yes. The copper interface is standard 1GbE Ethernet. Any PoE-compatible IP camera, access point, router, or managed switch will work. The converter does not inspect or filter traffic.
Q: How much power does the central-side F-POE-G2 require?
A: Exact input wattage is not documented in available specs. The unit injects power onto the fiber to support remote devices; size your central PoE supply (or AC mains if the converter has an AC input option) based on remote load plus converter overhead. Consult the vendor for typical power draw.
Q: Is the F-POE-G2 NDAA-compliant or restricted for federal use?
A: No NDAA, TAA, or government certification is documented. This product is intended for enterprise, carrier, and integrator deployments without federal restrictions. Confirm with your procurement team if compliance is required.

The F-POE-G2 solves a real deployment constraint in fiber-first networks. Many sites have dark fiber or existing runs but lack the appetite to run separate electrical feeds to remote gear. This converter pair eliminates that friction. In campus builds and carrier deployments, the F-POE-G2 is genuinely useful for powering distant access points and security cameras where running new copper would be cost-prohibitive or logistically impossible.
Technical Highlights:
- 1 Gbps Bidirectional Throughput: Sufficient for concurrent camera feeds and backhaul traffic at a single remote site. Not a bandwidth bottleneck for typical edge deployments (single AP or handful of cameras). If you need to aggregate multiple high-bitrate streams from one location, confirm the 1 Gbps ceiling won't constrain your use case.
- Integrated Power Over Fiber: The remote unit draws all its power from the fiber link itself—no AC mains, no generator, no DC feed required at the far end. This is a massive operational simplification in rural, rooftop, or DAS scenarios. Size your central PoE infrastructure to handle both converter overhead and remote device load; undersizing the central supply will starve the remote end.
- Pair-Only Operation: Always deploy in matched units. A single converter is non-functional. This is not a downside if you understand it upfront, but it does mean you cannot pilot one unit before committing to the pair.
- 1.150 lb Compact Footprint: Mounts easily near fiber patch panels or in MDF spaces. Reduces installation complexity compared to larger media converters that require dedicated rack space or power distribution.
Deployment Considerations:
- Test fiber continuity and polarity before energizing. Swapped RX/TX leads will cause silent data loss. Polarity errors are rare but devastating on first power-up.
- The remote unit draws power from the fiber — if the central-side converter is undersized or the fiber link is noisy, the remote unit may brownout or reset. Size your central PoE supply generously and confirm fiber integrity with a light meter if you suspect power instability.
- No management interface on the F-POE-G2 itself — it is a dumb bridge. If you need to monitor converter health or power draw, you must track it indirectly via the devices it powers (AP reachability, camera uptime).
Position the F-POE-G2 in campus or rural wireless/surveillance deployments where fiber backbone already exists and electrical infrastructure does not. It shines in distributed antenna systems and rooftop access point scenarios where running AC or UPS to each remote site is impractical. If you are deploying a single remote device over short copper distances, standard PoE injectors and PoE switches are simpler and cheaper—reach for the F-POE-G2 when distance or site logistics genuinely demand it.
