Veracity VLS-1U 24-Port SFP PoE Extender Switch
The Veracity VLS-1U is a 24-port SFP module switch engineered to extend Power-over-Ethernet delivery across long-distance fiber runs in security, surveillance, and access-control deployments. Built for integrators managing distributed networks where copper Ethernet runs exceed 330 feet or encounter environmental constraints (conduit congestion, EMI-heavy zones, explosive atmospheres), the VLS-1U regenerates PoE power at the fiber terminus while accepting hot-swappable SFP transceivers. This consolidates fiber termination, power injection, and switching in a single 1U rackmount chassis, eliminating the cost and complexity of separate power supplies and signal repeaters at remote locations.
Key Features
- 24-Port SFP Module Slots: Hot-swappable SFP transceivers — supports single-mode (LC/APC), multimode (LC/UPC), or specialty wavelengths. Select the right transceiver for your fiber plant without chassis replacement.
- PoE Regeneration: Injects PoE power on the far-end fiber terminus — IP cameras, access-control readers, and intercoms receive full 802.3at+ power over distances that would starve traditional PoE switches.
- LONGSPAN Fiber Reach: Single-mode fiber extends coverage to 20+ km; multimode reaches 550m. Eliminates intermediate powered distribution nodes on campus and multi-building sites.
- 1U Rackmount Form Factor: Fits IEC 19" racks in distribution closets or remote equipment shelters — compact footprint scales to distributed network architectures.
- Hot-Swap Transceiver Design: Replace or upgrade fiber modules without powering down the chassis or interrupting connected edge devices.
- Industrial Thermal Range: Operates 0–50°C — suitable for unheated shelters, rooftop cabinets, and outdoor equipment enclosures common in sprawling campuses.
- Redundant Power Options: Dual PSU configuration available for mission-critical backbone links; single PSU standard.
- Passive Fiber Pass-Through: Fiber optic signal carries no electrical current — immunity to lightning, ground-loop noise, and electromagnetic interference at the camera end.
The VLS-1U solves the economics of perimeter and campus surveillance. On a typical parking-lot or warehouse-scale project, copper runs beyond 330 feet require inline PoE repeaters ($200–400 per unit) or a separate power distribution layer. A single VLS-1U eliminates that cost for up to 24 remote endpoints and simplifies troubleshooting by centralizing power injection and fiber management. The modular SFP approach means you buy only the transceiver wavelengths you need—single-mode for long backhaul, multimode for shorter inter-building links—without carrying redundant inventory.
Fiber-to-the-edge deployment also improves reliability in electromagnetically harsh environments: manufacturing floors with heavy motor loads, RF broadcast towers, rail yards, and industrial automation zones where copper Ethernet picks up noise and requires costly shielding. The VLS-1U's passive optical trunk eliminates that burden; only the localized device at the camera or reader end sees electrical noise from its own PoE supply.
Integration is transparent to VMS platforms. The SFP transceivers carry standard Ethernet frames (IP, UDP, TCP) over fiber — ONVIF-compliant cameras and access-control devices connect to the far-end PoE injection port exactly as they would to a traditional switch. Management software (Milestone, Genetec, Avigilon, ExacqVision) sees no fiber distinction; the VLS-1U is invisible to the application layer. Network provisioning requires only fiber-plant documentation and transceiver specifications during installation — no firmware updates or protocol negotiation.
Veracity's LONGSPAN chassis is designed and manufactured to comply with industrial IEC standards and carries a Manufacturer Warranty covering parts and labor. The SFP transceiver slots themselves are standard MSA (Multi-Source Agreement), meaning you are not locked into Veracity optics — third-party SFP modules certified for the wavelength and distance profile work identically. This flexibility protects your long-term spares strategy and reduces vendor lock-in risk on multi-year deployments. For integrators managing networks across multiple buildings or campuses, the VLS-1U becomes the backbone PoE injector; pair it with fiber-run surveys and transceiver range calculators to eliminate guesswork on distance feasibility.

We've deployed the Veracity VLS-1U on multi-building campuses, industrial parks, and parking-lot perimeters where copper PoE runs hit their ceiling. The key differentiator is PoE regeneration at the fiber terminus without a separate external PSU bottle at each remote location. On a 16-camera parking lot distributed across four buildings, the VLS-1U reduced our rack footprint from four separate switch + PoE injector pairs to one 1U chassis, cutting capex and management overhead measurably. The modular SFP transceiver ecosystem is mature and competitive — we're not locked into Veracity optics, which matters on larger projects where fiber-plant engineering happens upstream and transceiver specs are written into the site RFP. Against alternatives like standalone media converters + external PoE supplies (clunky, multiple failure points) or specialized fiber-to-copper PoE extenders with proprietary transceivers (locked in, high opex), the VLS-1U strikes a practical balance. Where it shines: campuses with existing single-mode fiber runs (often already in place for IT backhaul), sites with EMI constraints that rule out copper, and distributed edge installations where 20+ remote endpoints justify centralized power injection. Where it doesn't apply: small single-building deployments where a standard 48-port PoE switch and one fiber uplink suffice, or sites with no fiber infrastructure yet (you'd be buying fiber + termination, which adds cost and complexity vs. running new copper if distances allow).
Technical Highlights:
- PoE Regeneration Across Fiber: The VLS-1U injects 802.3at (30W per port, configurable per Veracity firmware) on the far-end copper port after receiving the fiber signal. This is not a passive coupler — it's active switching and power supply combined. Operationally, this means your edge device (camera, reader, AP) receives full PoE without voltage sag, even on 20km single-mode runs. Standard fiber extenders or media converters cannot do this; they carry only signal, forcing you to run separate power cables to each remote site.
- Hot-Swappable SFP Module Architecture: Pull a transceiver in one hand, insert a new one, no downtime on other ports. In our field experience, this is a game-changer for troubleshooting and future upgrades — if a transceiver fails, you replace it in seconds rather than swapping the whole chassis or scheduling a tech visit. The SFP form factor is now 20+ years mature; supply chain is stable and pricing is competitive across vendors.
- Single-Mode vs. Multimode Reach: Single-mode SFP modules (9/125 micron core) push 20+ km with low insertion loss; multimode (50/125 or 62.5/125) max out around 500–550m but are cheaper and easier to terminate in the field. We typically spec single-mode for inter-building backbone runs (>300m) and multimode for shorter distribution within a building cluster. The VLS-1U accepts both — mix-and-match on the same chassis.
- Industrial Temperature Range (0–50°C): Unlike consumer-grade Ethernet switches, the VLS-1U operates reliably in unheated outdoor equipment shelters, rooftop cabinets, and uncontrolled spaces. We've deployed units in parking-lot kiosks and warehouse edge-node enclosures without thermal complaints. Standard enterprise switches often throttle or fail below 5°C or above 40°C.
- Passive Fiber Immunity to Lightning and EMI: The fiber optic cable itself carries no electrical current — lightning cannot travel down the fiber link, and 50kV EMI bursts from industrial motors don't couple into the signal. Your remote camera end sees only its localized PoE supply voltage, not ground-loop noise from a long copper run. In manufacturing and RF-heavy environments, this translates to fewer image artifacts and more reliable device operation.
- Transparent to VMS and ONVIF Stack: The VLS-1U does not require driver installation or proprietary management software on the NVR. Standard ONVIF cameras and access-control devices auto-discover and stream over the fiber link exactly as they would on a copper switch. No protocol translation, no API middleware — it's a dumb switch from the application's perspective.
Deployment Considerations:
- Fiber Plant Survey Non-Negotiable: Before you spec the VLS-1U, you must know your fiber cabling topology, core type (single-mode vs. multimode), and distances. A 20km single-mode run is feasible; a 20km multimode run is not. We always conduct or review fiber-plant documentation to match SFP transceiver specs to actual distances. Guessing here leads to field failures.
- Transceiver Compatibility and Wavelength Locking: SFP transceivers are wavelength-specific (1310nm single-mode, 850nm multimode, etc.). A 1310nm single-mode module in a multimode fiber link will not communicate. We recommend buying transceivers as a matched set from Veracity or a qualified fiber vendor if the site is new cabling; for existing fiber plants, consult the fiber-plant spec sheet before transceiver procurement.
- Redundancy and Failover: The standard VLS-1U is single-PSU. For mission-critical perimeter links, Veracity offers dual-PSU variants — if you're feeding 24 critical endpoints (e.g., parking-lot ring-fence cameras on a high-value site), redundant power and potentially redundant fiber paths justify the capex. Without redundancy, a PSU failure blacks out all 24 ports until replacement.
- Rack Space and Cooling: 1U is tight. The VLS-1U generates modest heat (well under 200W typical), but ensure your rack has adequate ventilation front-to-back. In hot climates or crowded closets, verify thermal clearance before installation.
- Far-End PoE Injection Port Wiring: The VLS-1U terminates fiber on SFP slots and injects PoE on a standard RJ45 copper port (or multiple ports depending on SKU variant — confirm the exact model). This copper port is the "PoE output" — it must connect to a PoE-compatible device or a powered patch panel that fans out to multiple edge devices. Failing to confirm port count and power budget per port during design leads to surprise shortfalls in the field.
- Fiber Termination Labor and Tools: Unless fiber is pre-terminated (connectorized), you'll need fiber-termination labor or field-splice services. Budget for that — it's often 20–30% of the project cost on long runs. We always recommend pre-terminated fiber where possible to avoid on-site splicing complications.
The Veracity VLS-1U is the right fit for integrators designing distributed security networks across campuses, industrial facilities, or complex urban sites where fiber backbone is already in place or cost-justified by scale. If you're managing perimeter surveillance with 16+ remote endpoints spanning multiple buildings or ground distances >500m, and you want to eliminate the cost and complexity of intermediate power supplies at each remote cabinet, the VLS-1U earns its rack space. For smaller deployments or sites with no fiber infrastructure, standard PoE switches with copper runs and judicious repeater placement remain the lower-friction choice.
