Altronix NETWAYSP4BTX 4-Port 90W PoE++ Fiber Media Converter with Wall-Mount Enclosure
Overview
The Altronix NETWAYSP4BTX is a wall-mount fiber media converter designed for security integrators who need to extend PoE-powered devices over fiber runs where copper won't reach. It combines four 10/100/1000 Mbps PoE++ access ports with two Gigabit SFP fiber uplinks, all enclosed in a NEMA 1 steel wall-mount cabinet with integrated power supply. This is not a tabletop switch you repurpose for a remote IDF closet — it ships as a self-contained unit ready to mount at the edge of a fiber-connected security zone. If you're deploying high-draw endpoints like pan-tilt-zoom cameras, multi-sensor panoramic units, or access control panels with electric locking hardware, the NETWAYSP4BTX is built to handle the load with up to 90W per PoE port and 240W total system power.
The unit supports IEEE 802.3af, 802.3at, and 802.3bt PoE standards, meaning it auto-negotiates power class with attached devices rather than forcing you to configure per-port budgets manually — a practical advantage when you're mixing 15W dome cameras with 60W or 90W PTZs on the same unit. For integrators sourcing infrastructure from the Altronix surveillance and power product line, the NETWAYSP4BTX sits at the convergence of their PoE and fiber product disciplines.
Key Features
- 90W Per-Port PoE++ (802.3bt): Each of the four access ports delivers up to 90W, which is the ceiling required by 802.3bt Class 8 devices. This covers the full range of current high-power IP security endpoints — multi-sensor cameras, PTZs with wipers and heaters, door controllers with integrated mag locks. You won't hit a power wall mid-deployment because you spec'd a PoE+ switch into a 90W application.
- 240W Total System Power Budget: The aggregate 240W budget means you can fully load two or three ports at near-maximum draw without crowding out the remaining ports. In a four-camera PTZ cluster where each unit draws 60–75W, the math works — no over-subscription. Budget your per-port loads before commissioning to confirm headroom, but 240W is a credible allocation for mixed-draw security installations.
- Dual Gigabit SFP Fiber Uplinks: Two SFP slots provide Gigabit uplink capacity over your choice of fiber media — single-mode long-haul or multimode for shorter in-building runs — dependent on the SFP transceivers you install. This lets you backhaul four PoE device streams over fiber to a central switch or NVR, eliminating the 100-meter copper constraint for remote buildings, parking structures, or campus perimeter deployments. Fiber also electrically isolates the remote location, relevant for lightning-prone outdoor environments. Browse PoE switches if you need a copper-based aggregation option instead.
- 10/100/1000 Mbps Auto-Negotiating Access Ports: Gigabit access ports mean you're not bottlenecking high-bitrate video streams at 100Mbps. Multi-sensor cameras running multiple streams at 4K or multi-megapixel resolutions can saturate a Fast Ethernet port — Gigabit access removes that constraint for bandwidth-intensive IP camera deployments.
