Altronix NETWAYSP1BT2WP 90W 802.3bt Outdoor PoE Injector with Dual SFP Fiber
Overview
The Altronix NETWAYSP1BT2WP is a single-port 802.3bt (4-pair PoE) power injector and power supply in a NEMA 4/4X, IP66-rated outdoor enclosure — built for deployments where you need to push 90W to a remote camera, PTZ, or access reader at the edge of a fiber run. It bridges dual 1Gb SFP fiber uplinks to a copper PoE output, making it the right tool for outdoor cabinet installations where fiber reaches the pole but the endpoint device still needs copper PoE. It complies with IEEE 802.3af, 802.3at, and 802.3bt, so it works with the full range of PoE device classes without manual configuration.
Key Features
- 90W 802.3bt (4PPOE) Output: With all four pairs delivering power, you can run high-draw endpoints — 30x optical zoom PTZ cameras, multi-sensor heads, or heated enclosures — from a single port. Most PoE+ injectors cap at 30W; this one doubles that headroom for devices that actually need it.
- Dual 1Gb SFP Fiber Uplinks: Two SFP slots let you extend the network reach far beyond copper's 100m limit. If your head-end switch is 500m away in a building, you run fiber to the enclosure, install the NETWAYSP1BT2WP, and terminate copper to your endpoint — no media converter required as a separate device.
- 10/100/1000 Mbps Data Rate to 100m: Full gigabit throughput on the copper CAT5e run to the endpoint device, supporting 4K video streams and high-bitrate multi-stream cameras without bottlenecking at the injector.
- NEMA 4/4X and IP66-Rated Enclosure: Rated for direct water spray, dust ingress, and corrosion — meaning this unit can mount in an outdoor pole cabinet or wall-mount can in a car wash, loading dock, or coastal perimeter without a secondary weatherproof housing.
- -40°C to 60°C Operating Range (at 90W): Full-load operation down to -40°C covers northern climate deployments where most commercial PoE injectors derate or fail. At reduced loads (60W), the range extends to 75°C — useful in solar-heated enclosures in summer.
- Built-in Battery Charging (48VDC, 0.75A): The integrated charging circuit supports sealed lead acid or gel batteries, letting you add local backup power inside the enclosure. For remote cameras that can't tolerate a network switch reboot pulling power, this is the path to resilient uptime without a separate UPS.
- 56VDC / 120W Power Supply Output: The internal supply runs at 120W total capacity, providing 90W to the PoE port with overhead for the charging circuit — no external power brick, no extra panel mount.
- Dual Voltage AC Input: Accepts 115VAC (60Hz, 2.5A) or 230VAC (50/60Hz, 1.3A), which simplifies international deployments or installations where only 230V outlets are accessible in the cabinet.
Integration and Compatibility
The NETWAYSP1BT2WP wires into standard 4-pair CAT5e or better to the endpoint device. The dual SFP ports accept standard 1Gb SFP transceivers — single-mode or multi-mode depending on your fiber run. It complies with IEEE 802.3af, 802.3at, and 802.3bt, meaning it negotiates correctly with any standards-compliant PoE device. For PoE network switches feeding fiber to the enclosure, the SFP uplinks terminate directly — no additional media converter needed in the cabinet. This unit fits naturally into Altronix power and network distribution architectures for perimeter and outdoor security installations. Pair it with a high-draw PTZ or multi-sensor camera from the PTZ camera category where 802.3bt is required.

Frequently Asked Questions
Q: What PoE standards does the NETWAYSP1BT2WP support?
A: It supports IEEE 802.3af, 802.3at, and 802.3bt — covering all three PoE generations. At 802.3bt (4-pair), it delivers up to 90W to a single port.
Q: Can the NETWAYSP1BT2WP be installed outdoors without an additional enclosure?
A: Yes. The enclosure is rated NEMA 4/4X and IP66, meaning it handles direct water spray, dust, and corrosion without a secondary housing. It is appropriate for outdoor pole mounts, wall mounts, and industrial cabinet installations.
Q: What fiber transceivers are compatible with the dual SFP ports?
A: The SFP ports support standard 1Gb SFP transceivers. The appropriate transceiver type (single-mode vs. multi-mode) depends on your fiber plant — select based on your run distance and fiber type.
Q: Does the NETWAYSP1BT2WP support battery backup?
A: Yes. An integrated 48VDC, 0.75A charging circuit supports sealed lead acid or gel-type batteries, enabling local backup power inside the enclosure for continued operation during AC outages.
Q: What is the operating temperature at full 90W output?
A: At 90W, the rated operating range is -40°C to 60°C. At 80W it extends to 70°C, and at 60W it reaches 75°C.
The NETWAYSP1BT2WP solves a specific problem I run into regularly on perimeter camera deployments: the fiber home-run gets you to the pole, but the 90W PTZ at the top needs copper PoE, needs power it can actually use, and needs to survive a Minnesota January at full load. This unit handles all three in a single NEMA 4X box — no media converter, no separate UPS, no heated enclosure fighting for cabinet space.
Technical Highlights:
- 90W 802.3bt Single-Port Output: At 90W on a single copper port, you can run the highest-draw PTZ cameras on the market — most 30x optical zoom units pull 60-80W under full operation. That headroom matters when the camera is heating its own dome in sub-zero weather.
- -40°C to 60°C at Full Load: The thermal derating table is real — at 60W it hits 75°C, at 90W it caps at 60°C. Size your load accordingly if the cabinet sees direct sun in summer climates where ambient can push 50°C inside a dark metal enclosure.
- Integrated 48VDC Battery Charging (0.75A): The built-in charger means you can drop a sealed lead-acid battery in the cabinet and get genuine UPS function without a second power supply occupying panel space or requiring separate wiring.
Deployment Considerations:
- Verify your SFP transceiver type before ordering — the dual SFP ports are 1Gb capable but you need to specify single-mode or multi-mode based on your existing fiber infrastructure. The unit does not ship with transceivers.
- The 100m copper distance limit applies at the PoE output. If your endpoint camera is mounted further than 100m from the cabinet, you need an additional fiber segment — this unit does not extend that limit on the copper side.
This is the right unit for a hardened outdoor camera node where a high-draw PTZ sits at the end of a fiber run in a climate with real winters — correctional perimeters, port facilities, and northern-climate highway monitoring are the scenarios where the -40°C rating and 90W output actually get used together.
