Altronix NETWAYSP1BTWPN 1G Fiber PoE Media Converter

Altronix NETWAYSP1BTWPN Single Port 1G Fiber PoE Media Converter

Overview

The Altronix NETWAYSP1BTWPN is a hardened fiber optic media converter and PoE switch designed for outdoor security and telecommunications deployments. This single-port device combines 1 Gigabit fiber connectivity with high-power PoE delivery in a NEMA 4/4X rated, IP66-sealed enclosure. The NETWAYSP1BTWPN supports 802.3bt 4-pair Power over Ethernet (4PPoE) output with up to 90W maximum power delivery, making it suitable for demanding edge devices, wireless access points, and surveillance equipment requiring extended range and environmental protection.

Key Features

• 1 Gigabit Fiber SFP Port: Single optical SFP transceiver slot for flexible fiber connectivity over extended distances without electromagnetic interference
• 802.3bt 4-Pair PoE Support: Delivers up to 90W maximum power to connected devices using all four pairs of standard twisted-pair cabling
• Single Gigabit Ethernet Output: One 10/100/1000 Mbps RJ45 port provides full-duplex data connectivity paired with PoE injection
• 48–56V DC Input: Accepts standard industrial DC input voltage range for flexible power source integration and compatibility with existing backup power infrastructure
• NEMA 4/4X Outdoor Enclosure: Fully sealed metal housing protects electronics from rain, dust, salt spray, and thermal extremes in outdoor installations
• IP66 Rating: Meets IP66 ingress protection classification for complete dust sealing and powerful water jet resistance
• Media Converter Architecture: Integrated fiber-to-copper conversion eliminates the need for separate conversion appliances, reducing deployment footprint and connection points

Integration & Compatibility

The NETWAYSP1BTWPN integrates seamlessly into security and telecommunications networks requiring long-distance fiber runs with simultaneous power delivery. The device operates as a midspan PoE injector with transparent media conversion, compatible with any standard 802.3 Ethernet device that accepts 4PPoE input. Fiber connectivity enables deployment beyond copper distance limitations (up to 10 km for single-mode or 500 m for multimode SFP modules, depending on optic selection). The 48–56V input range supports integration with battery backup systems, solar power supplies, and industrial DC power sources common in outdoor security infrastructure. Installation in the outdoor-rated enclosure eliminates the need for secondary weatherproof housings, reducing material cost and simplifying field wiring.

Technical Implementation

The NETWAYSP1BTWPN employs transparent layer 2 media conversion, preserving all Ethernet frames and PoE signaling across the fiber boundary. Power delivery operates independently of data traffic, allowing continuous device support even during network congestion or brief optical signal loss. The device's compact form factor and integrated design simplify installation in remote or difficult-to-access locations such as rooftop access points, perimeter lighting poles, and remote gate controllers.

Jerry Tildsen

I evaluated the Altronix NETWAYSP1BTWPN during the planning phase of a large perimeter deployment requiring fiber runs to multiple remote gateways. The combination of fiber connectivity with integrated 802.3bt PoE injection in a single, sealed outdoor enclosure eliminated the need for external power shelters and separate media converters—a significant reduction in bill of materials and installation labor.

Technical Highlights:

• 90W 4PPoE Delivery: Full 802.3bt support via all four twisted pairs enables deployment of power-intensive devices like PTZ cameras, dual-radio access points, and LED lighting controllers without secondary power runs
• Industrial DC Input (48–56V): Accommodates battery backup and solar integration without requiring additional power conditioning or conversion stages
• IP66 + NEMA 4/4X Enclosure: Eliminates field-fabricated weatherproofing and simplifies maintenance access in harsh coastal or high-temperature environments

Deployment Considerations:

• Verify SFP optic type and distance requirements before ordering—multimode for short runs (500 m), single-mode for extended distances (10+ km)
• Confirm end-device PoE Class rating and wattage draw against the 90W maximum budget, particularly when powering multiple chained devices

For integrators and telecom buyers managing outdoor fiber-to-copper conversions with simultaneous power delivery requirements, the NETWAYSP1BTWPN delivers dependable performance and simplifies logistics. The sealed enclosure design is especially valuable in cost-sensitive deployments where eliminating secondary shelters improves ROI.
