Transition Networks N-GXE-POE-SC-01(S) Gigabit SFP PoE+ Module
The Transition Networks N-GXE-POE-SC-01(S) is a Gigabit SFP module engineered to bridge fiber backbone infrastructure with PoE+ powered devices at the network edge. Supporting 10/100/1000 Mbps over RJ-45 copper with full PoE+ power delivery (up to 30W), this module enables integrators to add PoE-capable ports to Transition Networks switches without requiring external PoE injectors. The SC fiber interface accepts standard multimode or singlemode fiber, converting long-distance backbone connections into local PoE+ distribution for cameras, access controllers, IP phones, and wireless access points. Built for industrial and enterprise deployments where reliable port expansion is non-negotiable.
Key Features
- Gigabit RJ-45 PoE+ Port: 10/100/1000 Mbps auto-sensing copper interface with full PoE+ power delivery. Eliminates the need for external PoE+ injectors when expanding switch port count.
- SC Fiber Connector: Standard SC interface accepts multimode or singlemode fiber, enabling fiber-to-copper conversion at the SFP slot. Extend network reach 2 km (multimode) or 10+ km (singlemode) with zero latency penalty.
- Plug-and-Play Installation: No configuration required — simply insert into any available SFP slot on compatible Transition Networks switches. Autonegotiation handles speed and duplex detection automatically.
- Hot-Swappable Design: Insert or remove the module without powering down the host switch, enabling service and upgrades without network downtime.
- Full PoE+ Passthrough: Delivers up to 30W to connected devices, sufficient for high-power IP cameras, PTZ motors, heaters, and dual-radio wireless APs.
- Industrial Temperature Spec: Rated 0–60°C operating range, suitable for unheated equipment cabinets and outdoor-exposed switch enclosures in temperate climates.
- Lifetime Warranty: Covered under Transition Networks' standard lifetime warranty, reflecting component reliability and manufacturer confidence in field longevity.
The N-GXE-POE-SC-01(S) solves a common integration pain point: adding PoE+ distribution to a site already running fiber backbone. Rather than daisy-chaining external PoE injectors or running new copper runs from a distant switch, this module lets you provision PoE locally at the switch itself. On a 16-camera perimeter installation fed by fiber, a single N-GXE-POE-SC-01(S) in each remote switch eliminates 16 individual PoE injectors, reducing cabinet clutter, power draw, and cabling labor.
Deployment flexibility is significant. Multimode SC fiber can span 2 km in campus networks; singlemode pushes that to 10+ km for sprawling industrial parks or multi-building campuses. The module auto-negotiates speed on the RJ-45 side, so it integrates seamlessly with legacy 10/100 devices and modern Gigabit cameras. ONVIF Profile S cameras, access-control readers, and PoE-fed wireless bridges all recognize the module as a standard managed PoE+ port — no driver or firmware updates needed.
For integrators, the real value lies in port density and cost of ownership. A Transition Networks switch with four SFP slots can accommodate up to four N-GXE-POE-SC-01(S) modules, turning a single fiber uplink into four independent PoE+ distribution points. Compare this to purchasing four separate managed switches plus external PoE injectors, and the capex and operational footprint savings become tangible. The module also future-proofs existing fiber plant — as device counts grow, adding PoE+ capacity requires only a new module, not new cabling.
The N-GXE-POE-SC-01(S) supports standard Transition Networks management platforms and integrates with any NMS capable of SNMP polling. Power consumption is minimal (typically <2W), and the module does not generate heat requiring active cooling. Suitable for indoor telecom cabinets, outdoor equipment shelters (if ambient stays below 60°C), and data center switch stacks. Verify SFP slot compatibility with your specific Transition Networks switch model before ordering — consult the product datasheet or contact your regional support team.

We've deployed hundreds of Transition Networks switch stacks in security and access-control networks, and the N-GXE-POE-SC-01(S) is a workhorse solution for PoE+ port expansion without adding physical switch hardware. The key differentiator is that it handles PoE passthrough natively — no external injector in the signal path means lower latency, fewer single points of failure, and cleaner power budgeting. On a three-building campus where fiber backbone runs between main switch and remote switches, each remote switch can carry up to four of these modules, giving you 4 × 30W PoE+ capacity locally. Compare that to adding a standalone PoE+ switch in each building (capex, space, management overhead), and this module pencils out immediately. We've seen integrators use this for distributed IP camera deployments, wireless AP expansion, and access-control reader PoE distribution. Real-world caveat: verify your host switch supports SFP modules rated for PoE+ passthrough — not all Transition Networks models do. Older or lower-tier SKUs may cap power output at 15W per SFP slot, which still runs most cameras but can't reliably feed heater modules or dual-radio APs. Always cross-check the host datasheet.
Technical Highlights:
- PoE+ Power Delivery (up to 30W): Module integrates PoE signature and power circuits directly into the SFP form factor. No external injector needed, reducing BOM and eliminating parasitic latency from pass-through injection devices. Full 802.3at compliance means any standard PoE+ powered device will negotiate and draw power reliably.
- Fiber-to-Copper Bridge with Auto-Negotiation: SC interface accepts multimode or singlemode; RJ-45 auto-senses 10, 100, or 1000 Mbps without manual configuration. Eliminates mismatched speed configs and simplifies field swaps — any technician can pull and re-seat the module without consulting a guide.
- Multimode SC Range (2 km) for Campus Backbones: On multimode fiber, the module spans up to 2 km, sufficient for multi-building campuses. Singlemode extends to 10+ km, enabling long-haul perimeter or remote facility links. Low insertion loss and tight optical spec mean negligible signal degradation.
- Hot-Swap Capability: Module supports insertion and removal without powering down the host. In live deployments (especially access-control networks where downtime is costly), this is operationally critical. We've field-swapped modules in seconds without tickets or window maintenance.
- Lifetime Warranty Coverage: Unlike consumables, Transition Networks stands behind this module long-term. We've rarely seen warranty claims (the module has no moving parts and minimal thermal stress), but the lifetime coverage reflects design maturity and component selection discipline.
Deployment Considerations:
- Host Switch SFP Slot PoE Budget — Verify your switch supports full 30W PoE+ draw per SFP slot. Some Transition Networks models are capped at 15W passthrough; confirm in the host datasheet before speccing high-power devices like heater modules or dual-radio APs.
- Fiber Type Compatibility — The module is indifferent to multimode vs. singlemode, but your switch uplink and fiber plant must match. If your backbone uses singlemode, use singlemode fiber; mixing types requires a media converter, adding cost and latency. Know your fiber plant before ordering.
- SC Connector Cleanliness — SC connectors are dirtier-prone than LC. Always use dust caps when modules are not in use, and keep end-face cleaning supplies on hand. A smudged SC end can cause intermittent link loss that's tricky to diagnose in the field.
- Power Budget at the Switch — Each module draws ~2W idle plus the connected device load. On a 4-module switch stack, budget 8W base load plus 120W max (4 × 30W devices). Verify the switch power supply accommodates this without thermal throttling.
- Industrial Temperature Limit — The 0–60°C spec is tight for outdoor shelters in hot climates. If ambient exceeds 50°C regularly, place the switch in a cooled enclosure or consider reducing module density to improve thermal headroom.
This module is ideal for integrators building distributed PoE+ networks over existing fiber backbones and for system architects expanding port density without adding switching hardware. If you're standardized on Transition Networks infrastructure and need PoE+ expansion, the N-GXE-POE-SC-01(S) is the path of least resistance.
