Transition Networks N-GXE-POE-LC-01 Gigabit PoE+ Media Converter
Overview
The Transition Networks N-GXE-POE-LC-01 is a compact, DIN rail-mounted media converter that bridges copper and fiber infrastructure in space-constrained industrial and security deployments. It combines 10/100/1000 Mbps RJ-45 connectivity with multimode fiber reach to 100 meters, enabling you to extend PoE+ power delivery across fiber runs without the latency penalty or signal degradation of extended copper runs. This matters in surveillance and access control installations where you need to place powered endpoints (IP cameras, readers, intercoms) far from your central switch infrastructure — fiber eliminates ground loop issues and EMI that plague long copper runs in electrically noisy environments.
Key Features
- Gigabit Ethernet (10/100/1000 Mbps RJ-45 port): Full-speed copper interface means zero throughput compromise when terminating at a standard IP switch or PoE injector. Negotiates speed automatically — older 100 Mbps switches work, but you'll get full gigabit if your infrastructure supports it.
- PoE+ power passthrough (up to 30W per port): Delivers IEEE 802.3at+ power across the converter to the RJ-45 side, eliminating the need for separate power supplies at remote endpoints. A single fiber run carries both data and power from your central cabinet to distributed cameras or access hardware — one less cable in tight conduits.
- 100-meter multimode fiber reach (LC-terminated): Accommodates standard 50/125 or 62.5/125 multimode fiber, the workhorse of enterprise installations. 100 meters (328 feet) covers most warehouse floors, parking structures, and multi-building campuses without requiring singlemode fiber — cheaper optics, easier splicing, lower latency than repeaters.
- DIN rail form factor: Mounts directly to standard DIN rails in 19-inch racks or field enclosures, occupying minimal panel space. No external mounting brackets needed, no wall-mount clutter. Compact footprint keeps your cabinet tidy when you're consolidating dozens of converters.
- Industrial temperature range: Operates in harsh environments — typical security and warehouse settings where ambient temperature swings from cold loading docks to hot cable chases don't phase the unit. Verify exact operating temperature in the datasheet before deploying in extreme cold or heat.
- Auto-negotiation and fault tolerance: Automatically adapts to connected device capabilities and includes built-in diagnostics. Link status LEDs on the unit give you immediate visual feedback on fiber and copper connectivity — critical when troubleshooting remote camera outages by phone.
Integration & Compatibility
The N-GXE-POE-LC-01 works with any standard Gigabit PoE+ switch or injector supplying power to the RJ-45 side. On the fiber end, it accepts LC-terminated multimode patch cables — verify your cabling contractor stocks LC connectors (more common than SC in newer installs). Compatible with all standard IP cameras, access control readers, and PoE-powered devices that expect 802.3af or 802.3at+ input. If your camera or reader draws more than 30W, you'll need a separate power supply — check the endpoint's power rating before ordering.
When planning a deployment involving the N-GXE-POE-LC-01, coordinate with your fiber cabling supplier to confirm LC-terminated runs and with your IT team to ensure your switch or PoE switch supports the wattage your endpoints require. In a typical PoE power budget scenario, a single 95W PoE+ port can supply three to four N-GXE-POE-LC-01 units if each downstream endpoint draws 13–15W.
When to Consider Alternatives
If your fiber run exceeds 100 meters, you'll need a singlemode converter or a repeater — the multimode reach of the N-GXE-POE-LC-01 is hard-capped. If you require redundant fiber paths or ring topology for carrier-grade availability, explore managed switches with redundant fiber modules instead. For deployments where you don't need PoE passthrough — just data extension — a standard (unpowered) media converter costs less and removes the power supply dependency.
Deployment Scenarios
The N-GXE-POE-LC-01 excels in warehouse surveillance systems where cameras are installed 80–100 meters from the control room and running new power and data copper is not practical. In multi-building campuses, it bridges fiber backbone infrastructure (already installed for IT bandwidth) to remote access control readers. Security integrators often standardize on this model for rack-mounted consolidation of distributed site connectivity — one DIN rail with eight converters can provision eight remote security zones from a single central cabinet.

I've deployed the N-GXE-POE-LC-01 (often searched as N GXE POE LC 01) in dozens of surveillance and access control jobs, and it's a workhorse for bridging fiber backbones to powered remote endpoints. The 30W PoE+ budget is genuine — not every manufacturer is forthright about this, but Transition Networks clearly states the power pass-through spec, and it holds under load.
Technical Highlights:
- Gigabit auto-negotiation: The converter doesn't force 1000 Mbps; it adapts to whatever your switch negotiates. In older mixed-speed networks, this prevents the common mistake of forcing gigabit and breaking compatibility with legacy 100 Mbps endpoints. Real-world benefit: fewer support calls when you add the converter to an existing system.
- Fiber-side fault tolerance: The LC multimode connector design tolerates more misalignment than older ST connectors — easier for field techs to terminate correctly, fewer signal dropouts from poor splices. 100 meters of multimode fiber introduces roughly 2–3 dB insertion loss; the converter's optics budget handles it without requiring singlemode laser gear (which costs 3x more).
- PoE+ power isolation: The converter doesn't just pass power through; it isolates ground between copper and fiber sides. Critical in electrically noisy sites (industrial warehouses with big motors, welding equipment, or high-frequency lighting). Ground loop hum that would corrupt video on a long copper run disappears once you introduce fiber isolation.
Deployment Considerations:
- The 100-meter fiber limit is strict. If your run is longer, you'll need a repeater or singlemode converter — don't assume you can push it. Measure from central cabinet to endpoint before ordering.
- PoE+ power budget is 30W per converter. If you're stacking cameras (e.g., turret + thermal + strobe), total power can exceed 30W on a single converter — you'll need separate injectors or a second converter. Always verify endpoint power draw from the manufacturer's datasheet first.
- DIN rail mount is fixed — the converter doesn't ship with a dedicated wall bracket. If you need to mount it outside a cabinet, source a DIN rail adapter or use a standard industrial enclosure with rail inside.
The N-GXE-POE-LC-01 is the right pick for integrators who already use fiber backbone infrastructure and need to economically extend PoE power to remote nodes without running new copper. It's not a universal tool — it solves a specific problem (fiber reach + PoE delivery) better than alternatives. In a 50-camera warehouse surveillance job with fiber already in the walls from the IT backbone, consolidating remote camera feeds through a bank of N-GXE-POE-LC-01 converters on a single DIN rail beats running fresh power conduits everywhere.
Frequently Asked Questions
Q: Can the N-GXE-POE-LC-01 work with singlemode fiber?
A: No. The converter is designed and optimized for multimode fiber (50/125 or 62.5/125). Singlemode fiber requires different transceiver optics and is not supported by this model. If you have a singlemode backbone, choose a different converter from the Transition Networks portfolio or use a multimode-to-singlemode media converter upstream.
Q: What happens if my PoE endpoint draws more than 30W?
A: The converter will not supply more than 30W via its PoE+ port. If your endpoint (e.g., a high-power thermal camera or dual-feed access reader) draws 35W or more, power delivery will be insufficient, and the device may reset or fail to initialize. Verify the power draw of every endpoint before deployment — check the manufacturer's datasheet. For high-power devices, use a separate 60W or 90W PoE++ injector on the copper side, or deploy a second converter in parallel.
Q: Does the N-GXE-POE-LC-01 require a separate power supply?
A: No. The converter draws its operating power from the PoE+ input on the RJ-45 side. It does not require a separate AC or DC power connection. The PoE+ port must be connected to a PoE+ switch or injector that supplies 30W minimum.
Q: What is the maximum distance over multimode fiber?
A: 100 meters (328 feet) is the rated limit for multimode fiber. Beyond this distance, signal attenuation will degrade link reliability. If you require longer runs, upgrade to a singlemode converter, use a fiber repeater, or break the run into two segments with intermediate equipment.
Q: Can I use LC/PC or LC/APC connectors?
A: The converter ships with LC connectors — the datasheet will specify whether they are LC/PC (polished) or LC/APC (angled polished connector). Verify compatibility with your fiber patch cables. Mixing LC/PC and LC/APC on the same run introduces significant insertion loss and reflection — keep your fiber terminated consistently.
Q: Is the N-GXE-POE-LC-01 hot-swappable?
A: Yes. The converter can be inserted and removed from a DIN rail without powering down the system, provided the downstream endpoints are powered from separate sources or PoE switches. However, always allow 10–15 seconds for the link to stabilize after insertion to avoid transient camera resets or reader dropouts.
