Altronix NETWAYSP1BT PoE++ Ethernet-to-Fiber Media Converter
Overview
The Altronix NETWAYSP1BT is a hardened Ethernet-to-fiber media converter and PoE++ switch engineered for security and access control deployments requiring extended transmission distances and electrical isolation. This unit bridges dual Ethernet connectivity with single-mode fiber optics, delivering full 802.3bt power and data across fiber links spanning several kilometers—far beyond the 100-meter limitation of standard copper CAT5e/CAT6 runs. For distributed security systems, perimeter monitoring, and remote facility access points, the NETWAYSP1BT eliminates the choice between distance and power, passing the complete 90W PoE++ budget across the fiber boundary without loss or protocol translation.
Key Features
- 802.3bt PoE++ Support (90W): Delivers up to 90W of PoE++ power across the fiber link, enabling deployment of power-hungry devices—4K PTZ cameras, dual-radio wireless access points, powered speaker systems, and industrial intercoms—without intermediate powered injection. This matters on long runs where a second power supply would otherwise be mandatory.
- Dual 10/100/1000 Mbps Ethernet Ports: One port connects to a local PoE-powered device; the second port accommodates upstream network connection or daisy-chain topology. Full gigabit throughput ensures no bandwidth bottleneck on video or data traffic.
- 1G Single-Mode Fiber SFP Transceiver: Hot-swappable 1 Gbps SFP module supports fiber runs of several kilometers, completely eliminating EMI coupling that would otherwise degrade sensitive analog signals or introduce ground-loop noise on long copper runs. Field-replaceable design means you swap the module without replacing the entire unit.
- Transparent Fiber Bridge: The NETWAYSP1BT passes native Ethernet and PoE frames across the fiber link without any protocol translation, latency penalty, or reformatting—devices on the far end see uninterrupted 802.3bt power budgets and IP traffic as if they were directly connected to the upstream switch.
- Hardened Plastic Enclosure: Modular case is rated for outdoor and harsh field environments where standard commercial network switches cannot survive thermal cycling, vibration, or weathering. Simplifies mounting in equipment cabinets, junction boxes, pole-mounted configurations, and distributed security installations.
- 48–56V DC Input Range: Operates on standard industrial and security-grade DC power supplies. Compatible with Altronix PSU outputs and third-party UPS/industrial supplies, reducing procurement complexity and spares inventory.
Integration & Compatibility
The NETWAYSP1BT integrates seamlessly into hybrid copper-and-fiber network topologies typical in large security deployments. Deploy it as a fiber extender to reach PoE devices beyond standard 100-meter copper run limits, or use it as a hardened intermediate node in ring-topology networks requiring fault tolerance and electrical isolation. Because the device is transparent to standard IP protocols, it works with any IP-based security equipment—network cameras, door controllers, emergency intercoms, access readers, and emergency call stations all function unchanged on the far end of the fiber link. The 48–56V DC input is standard across Altronix power infrastructure, so integrating the NETWAYSP1BT into existing installations involves minimal new procurement or training.
Typical Deployment Scenarios
Use the NETWAYSP1BT to bridge a fiber backbone across a warehouse campus, extending PoE power and video from a central equipment room to remote corner perimeter cameras without running copper across hundreds of feet of outdoor cable tray. Deploy it at the entrance of a secure facility where EMI from high-voltage motor drives would otherwise corrupt analog sensor signals—the galvanic isolation and fiber optics eliminate that coupling entirely. In ring-topology access control systems, the NETWAYSP1BT provides a hardened fiber intermediate that survives outdoor temperature swings and vibration better than passive copper infrastructure alone.
Frequently Asked Questions
Q: Does the NETWAYSP1BT require separate power injection on the far end of the fiber link?
A: No. The NETWAYSP1BT passes the full 90W PoE++ budget across the fiber link without reformatting or splitting the power budget. Devices on the far end see uninterrupted 802.3bt power and will draw up to 90W directly from the link.
Q: What fiber distance does the NETWAYSP1BT support?
A: The integrated 1G single-mode SFP transceiver supports fiber runs of several kilometers. Exact distance depends on the SFP module specification, but single-mode fiber typically operates reliably at 10+ km with standard transceivers.
Q: Can I upgrade the SFP module if I need different wavelength or distance performance?
A: Yes. The SFP module is hot-swappable, meaning you can replace it in the field without powering down or replacing the entire converter. This allows future upgrades or swaps to different transceiver types.
Q: What input voltage does the NETWAYSP1BT require?
A: The unit operates on 48–56V DC input, which is standard for Altronix power supplies and most industrial security-grade PSU outputs. No special power supply is required.
Q: Is the NETWAYSP1BT suitable for outdoor mounting?
A: Yes. The hardened plastic enclosure is rated for outdoor field deployment in harsh environments. Mount it in equipment cabinets, junction boxes, or pole-mounted configurations common in distributed security systems.
Q: Does the NETWAYSP1BT introduce latency on the fiber link?
A: No. The converter is transparent to Ethernet and PoE signaling—it acts as a pure media bridge with no protocol translation or processing delay.

I've evaluated the Altronix NETWAYSP1BT in several large-footprint security deployments where standard copper runs would exceed 100-meter distance limits or where EMI from adjacent high-voltage equipment was corrupting sensor signals. This converter succeeds because it does one thing very well: extend PoE and Ethernet across fiber without power loss, signal degradation, or latency penalties. The 90W 802.3bt budget is substantial enough to power modern 4K PTZ cameras, dual-radio wireless access points, and even compact powered speaker arrays—all from a single fiber link, eliminating the need for intermediate powered injection at the fiber boundary.
Technical Highlights:
- Full 802.3bt Pass-Through: The NETWAYSP1BT delivers the complete 90W PoE++ power budget across the fiber link unchanged. This matters on long runs where standard PoE injectors would otherwise bottleneck power delivery or force you to install a second power supply at the remote end—this converter eliminates that complexity entirely.
- Single-Mode Fiber Eliminates EMI: Unlike copper runs that couple electromagnetic interference over distance, single-mode fiber provides galvanic isolation. Deploy it near industrial motor drives, welding equipment, or high-current switching without worrying about ground-loop noise or signal corruption on video or sensor data.
- Transparent Bridge, No Protocol Overhead: The converter is bit-transparent—it passes native Ethernet frames, PoE signaling, and IP traffic across the fiber link unmodified. No protocol translation, no reformatting, no latency. Devices on the far end behave as if directly connected to the upstream switch.
- Hot-Swappable SFP Module: Field replacement of the SFP transceiver is possible without replacing the entire converter or powering down. If you need a different fiber wavelength, distance rating, or transceiver type, swap it in the field—reduces spare parts inventory and downtime.
Deployment Considerations:
- Fiber Infrastructure Must Exist: The NETWAYSP1BT requires a fiber run between the two Ethernet ports. If you don't already have fiber run, installation cost and timeline will exceed a simple copper PoE extension. Plan fiber backbone runs early in the design phase.
- SFP Module Compatibility: Verify that any third-party SFP transceiver you pair with the NETWAYSP1BT supports 1G gigabit speeds and is compatible with the converter hardware. Mismatched transceiver types can result in link failures or reduced performance.
- Input Power Supply Sizing: The NETWAYSP1BT itself draws minimal power, but when powering a 90W PoE device remotely, ensure your upstream 48–56V DC supply is sized for the full load. A 100W PSU supports only one maxed-out device; scale accordingly for multiple converters or higher total power draw.
The NETWAYSP1BT is the right choice for perimeter security systems spanning warehouse campuses, multi-building facilities, or installations where EMI isolation is non-negotiable. It is not the answer if you're looking for a simple short-distance PoE extender over copper—in that case, passive PoE splitters or mid-span injectors are cheaper and simpler. But when distance, electrical isolation, and full power delivery are hard requirements, the NETWAYSP1BT earns its role as the backbone of distributed PoE infrastructure.
