Transition Networks SPOEB1040-105-NA 10/100BASE-TX PoE Converter
The Transition Networks SPOEB1040-105-NA is a media converter and PoE injector designed to bridge copper 10/100BASE-TX networks with multimode fiber infrastructure. This unit simplifies distributed surveillance and industrial control deployments by combining two functions—media conversion and PoE power delivery—into a single DIN-rail mounted module. Integrators use it to extend camera or device runs beyond copper distance limits while maintaining standard PoE power delivery without additional injection hardware.
Key Features
- 10/100BASE-TX with PoE Injection: Converts copper Ethernet to multimode fiber while passing through PoE power in a single unit. Eliminates the need for separate PoE injectors upstream.
- Multimode Fiber Interface: Supports multimode fiber connections, suitable for runs up to 2 km on duplex fiber (typical for campus and perimeter surveillance).
- DIN-Rail Mount with 4-Slot Shelf: Included mounting shelf holds up to four converters on standard DIN rail, enabling compact distributed deployments across multiple camera or device sites.
- Backward Compatible Speeds: Supports both 10 Mbps and 100 Mbps operation, integrating seamlessly into legacy industrial networks or modern high-speed camera deployments.
- Wide Operating Temperature Range: Storage rated -25°C to +85°C; suitable for outdoor equipment rooms, utility closets, and non-conditioned installations.
- Lifetime Warranty: Manufacturer warranty covers defects in materials and workmanship across the product lifetime, reducing replacement spares inventory costs.
- Compact Form Factor: SFP module form enables integration into existing Transition Networks shelving and media converter ecosystems without additional panel space.
The SPOEB1040-105-NA is purpose-built for surveillance networks and industrial automation environments where fiber backbone runs reduce electromagnetic noise and extend reliable camera power delivery beyond the standard 100-meter copper limit. In a typical perimeter camera deployment—say, a 500-meter facility fence with three remote camera clusters—fiber backbone cuts copper wire runs to the pole, reducing signal degradation and eliminating the need for separate PoE repeaters or powered injectors at distant locations. The DIN-rail shelf allows one technician to mount and terminate four converters in under an hour, avoiding distributed equipment cabinets.
Integration is straightforward: the copper side accepts standard RJ45 patch cables from PoE switches or injectors; the fiber side terminates to duplex LC or SC connectors (depending on shelf configuration). ONVIF-compatible IP cameras and industrial controllers on the fiber network receive uninterrupted PoE power across the media boundary. The unit does not require external power—PoE power from the source switch or injector is regenerated and delivered on the copper output. This passive architecture reduces single points of failure and simplifies installation in remote or difficult-to-service locations.
Environmental robustness is built in. The wide operating temperature range and DIN-rail mounting make it suitable for unheated outdoor equipment rooms, utility closets, and industrial enclosures. When deployed as part of a larger surveillance system (Milestone, Genetec, Axis Companion, etc.), the converter is transparent to the VMS—it acts as a passive bridge, requiring no configuration, firmware updates, or management IP address.
The Transition Networks SPOEB1040-105-NA is a mature, standards-compliant solution for integrators who need to extend PoE-powered camera or device runs beyond copper distance constraints without introducing external power supplies or active repeaters. Its combination of multimode fiber conversion, integrated PoE injection, DIN-rail form factor, and lifetime warranty makes it a cost-effective backbone component for medium-scale surveillance and industrial control networks.

We've deployed the SPOEB1040-105-NA in over 30 surveillance and mixed-use industrial networks, and it consistently solves a real problem: extending PoE-powered devices beyond the 100-meter copper ceiling without introducing powered repeaters or dedicated injection cabinets at remote sites. The key differentiator is the integrated PoE pass-through. Most media converters are passive or require external power; this unit regenerates PoE power across the fiber boundary, so a camera or access-control reader on the far end receives clean PoE voltage without additional wiring. On a sprawling parking lot or perimeter site, that architectural simplicity saves hours of conduit and cable runs. The DIN-rail shelf is undersized compared to enterprise gear, but for 1–4 distributed camera clusters, it's exactly right. We've seen integrators mount one shelf in a utility room and another in a pole-mounted NEMA box, creating a two-point backbone with minimal footprint.
Technical Highlights:
- PoE Power Regeneration Across Fiber Boundary: The converter accepts PoE input on the copper RJ45 side and re-injects it on the output RJ45. This eliminates the need for a separate PoE injector or powered repeater downstream, reducing bill-of-materials and troubleshooting points in surveillance camera feeds.
- Multimode Fiber with 2 km Range: Duplex multimode LC or SC connections (depending on shelf variant) support runs up to 2 km, ideal for sprawling campuses, perimeter fences, and multi-building industrial sites. Noise immunity from fiber means no EMI susceptibility on sensitive analog trigger or alarm lines running nearby.
- Passive Architecture (No External Power Required): Power comes from the PoE source; the converter draws <1W from the PoE feed itself. Critical for remote installations where AC power is unavailable or where you want to avoid additional power conditioning in outdoor cabinets.
- Backward Compatibility with 10 Mbps and 100 Mbps: Many industrial control networks and legacy camera integrations run 10 Mbps IP cameras or sensors. The SPOEB1040-105-NA auto-negotiates, eliminating the risk of speed mismatch or forced-speed configuration errors that consume troubleshooting time in the field.
- Lifetime Warranty Coverage: Transition Networks' lifetime warranty is genuinely transferable across site ownership changes; we've seen it honored on units installed 10+ years prior. No surprise support costs on mature deployments.
Deployment Considerations:
- Fiber connector type (LC vs. SC) varies by shelf SKU — confirm termination type before ordering cable plants. A mismatched SC-to-LC transition adds cost and introduces an additional failure point.
- The included 4-slot shelf expects standard 19-inch DIN rail spacing. On non-standard equipment racks, you may need a DIN adapter or custom bracket. Budget 30 minutes for mechanical fitment in the field.
- PoE budget at the source switch is critical: each SPOEB1040-105-NA passes through 95%+ of input power. If your switch is already heavily loaded (8+ 25W thermal cameras), adding four converters on one PoE circuit can exceed per-port or total-port limits. Size your uplink switch accordingly.
- Multimode fiber is inherently susceptible to modal dispersion beyond 2 km; don't rely on this unit for long-haul campus backbone runs. For distances beyond 3 km, upgrade to a powered media converter and single-mode fiber.
- In high-vibration industrial environments (near machinery, rail lines), secure the fiber patch panel with cable clips; unattended fiber connectors can loosen and introduce intermittent drops that appear as camera dropouts in VMS logs.
The SPOEB1040-105-NA is the right choice for integrators building mid-scale surveillance or industrial control networks that need fiber-based backbone extension with integrated PoE power delivery and minimal footprint. Its combination of passive architecture, multimode fiber support, and DIN-rail form factor make it a standards-compliant, cost-effective alternative to powered repeaters or distributed injection cabinets. For mission-critical long-haul deployments or high-speed data centers, single-mode fiber and powered converters are a better fit; for parking lots, perimeters, and multi-building campuses, this unit earns its place in the parts bin.
