Altronix NETWAYSP1BT2WPN 90W 802.3bt Fiber-to-RJ45 PoE Injector/Converter
Overview
The Altronix NETWAYSP1BT2WPN is a single-port 802.3bt PoE injector and media converter built for outdoor surveillance infrastructure that needs to bridge fiber backbone runs to a high-power copper endpoint — think PTZ cameras, multi-sensor heads, or access control readers at the far edge of a campus. It accepts 48–56VDC input, delivers up to 90W of IEEE 802.3bt PoE on a single RJ45 port, and passes data over dual gigabit SFP fiber interfaces rated to 1Gbps — all inside a NEMA 4/4X, IP66-rated enclosure that tolerates direct rain, washdowns, and industrial contamination without a secondary housing.
Key Features
- 90W 802.3bt PoE Output: Full Type 4 / Class 8 power delivery over a single RJ45 — enough headroom to run high-draw PTZ cameras, multi-sensor panoramic units, or PoE-powered access control panels that choke on standard 802.3at (30W) injectors. Also backward-compatible with 802.3af and 802.3at devices.
- Dual 1Gb SFP Fiber Ports: Two gigabit SFP slots let you loop the fiber run or connect to two upstream switches without a separate media converter. Fiber carry eliminates ground-loop risk across buildings and extends the copper segment to 100m from the injector — fiber distance depends on the SFP module selected.
- NEMA 4/4X + IP66 Enclosure: Rated for outdoor and industrial environments including hose-directed water and corrosion. Installs in junction boxes, on poles, or in outdoor equipment cabinets without additional weatherproofing. The IP66-11 rating means high-pressure washdowns common in food processing or loading dock environments won't penetrate the housing.
- Wide Operating Temperature Range: At 60W load, rated -40°C to 75°C. At 80W, rated to 70°C. At full 90W, rated to 60°C. The -40°C cold floor means this unit deploys in northern outdoor environments without heater accessories — a direct cost reduction on pole-mount or cabinet installs where ambient heat is unavailable.
- 95W Input / 90W Output Budget: The 48–56VDC input draws a maximum of 1.9A (95W input ceiling), delivering 90W to the PD. That 5W conversion overhead is efficient for a unit of this class and keeps the upstream power supply sizing straightforward.
- 10/100/1000 Mbps Auto-Negotiating Data Port: Full gigabit throughput to the downstream device at up to 100m on the RJ45 segment. No manual speed configuration needed — the port auto-negotiates to match connected endpoints.
- Altitude-Rated to 2,000m: Validated for high-elevation deployments (304.8m–2,000m operating range) where reduced air density can affect thermal performance of sealed electronics — a spec most injectors omit entirely.
Integration & Compatibility
The NETWAYSP1BT2WPN integrates into any fiber-backbone surveillance or access control network where the final copper drop requires PoE beyond 802.3at. SFP modules are field-selected to match your fiber type (single-mode or multimode) and run distance. The unit is passive from a management standpoint — no IP address, no SNMP — so it fits transparently into managed or unmanaged upstream switch environments. Pair it with an appropriately rated 48–56VDC power supply sized to the 1.9A input draw. For large deployments, Altronix mid-span and multi-port PoE products in the Altronix catalog cover centralized power architectures where individual injectors are impractical.
If your project involves running PoE network switches in the equipment room with fiber runs to edge locations, this injector fills the last-100m gap cleanly. For camera selection guidance and matching power budgets, the PoE planning guide covers load calculations for 802.3bt endpoints. If you're deploying outdoor IP cameras with high-wattage heater/fan assemblies, the 90W ceiling is the correct spec to verify first. For structured cabling infrastructure and network accessories that complete the run, those are stocked alongside this unit.
Frequently Asked Questions
Q: What PoE standards does the NETWAYSP1BT2WPN support?
A: It supports IEEE 802.3af, 802.3at, and 802.3bt — delivering up to 90W to a single 802.3bt (Type 4) powered device while remaining backward-compatible with lower-draw 802.3af/at endpoints.
Q: What input voltage and current does the NETWAYSP1BT2WPN require?
A: The unit requires 48–56VDC input at up to 1.9A (95W input maximum). Size your upstream power supply to that draw with appropriate margin.
Q: What is the operating temperature range?
A: At 60W output load, -40°C to 75°C. At 80W, -40°C to 70°C. At full 90W output, -40°C to 60°C. Storage temperature is -40°C to 85°C.
Q: Can the NETWAYSP1BT2WPN be installed outdoors without an additional enclosure?
A: Yes. The unit carries a NEMA 4/4X and IP66-11 rating — it withstands direct rain, hose-directed water, dust, and corrosion. No secondary weatherproof housing is required for standard outdoor pole or wall mounting.
Q: What fiber interface does the NETWAYSP1BT2WPN use?
A: It has dual 1Gb SFP ports. SFP modules are field-selected to match your fiber type and run distance — single-mode or multimode modules are available from standard suppliers.
Q: What is the maximum copper Ethernet distance from the NETWAYSP1BT2WPN to the powered device?
A: Standard 802.3 100m maximum on the RJ45 port at 10/100/1000 Mbps.
The NETWAYSP1BT2WPN is the unit I specify when an integrator needs to deliver 90W of 802.3bt PoE at the end of a fiber run — specifically for high-draw outdoor edge devices where running a separate power home-run back to the IDF isn't practical. The combination of dual gigabit SFP ports and a NEMA 4X/IP66 steel enclosure means you can mount this on a pole or inside an outdoor cabinet and forget about it across seasonal temperature swings down to -40°C.
Technical Highlights:
- 802.3bt / 90W Output: Covers the full Type 4 power envelope — enough for PTZ cameras with integrated heater/fan assemblies that exceed the 30W 802.3at ceiling most mid-span injectors stop at.
- Temperature Derating by Load: At full 90W, the ceiling drops to 60°C ambient; at 60W, you get 75°C. In hot outdoor cabinet installations, verify your worst-case ambient against the load you're actually running — not the unit's published max.
- Dual SFP + Single RJ45 Architecture: Two fiber ports let you daisy-loop or dual-home without a separate media converter in the chain, which reduces failure points and cabinet clutter at remote edge nodes.
Deployment Considerations:
- Input power supply must be sized for 48–56VDC at 1.9A continuous — don't share this rail with other loads unless your supply has margin above 95W; inrush on 802.3bt negotiation can spike the draw briefly.
- SFP modules are not included — spec your fiber type, wavelength, and run distance before ordering to avoid a second delivery. Single-mode and multimode requirements differ substantially at distances beyond 550m.
This unit is the right call for perimeter PTZ deployments on fiber-backbone campuses — parking structures, port facilities, and remote gate stations where 802.3at falls short and running new copper home-runs is cost-prohibitive.
