Ubiquiti UACC-OM-MM-1G-D-2 1 Gbps Multi-Mode Optical Transceiver
Overview
The Ubiquiti UACC-OM-MM-1G-D-2 is an SFP transceiver module engineered for fiber connectivity within UniFi infrastructure deployments. This module operates at 1 Gbps throughput over multi-mode fiber optic cable, delivering reliable performance across campus networks, distributed facilities, and warehouse automation systems where longer-distance Ethernet runs are required without copper limitations.
The UACC-OM-MM-1G-D-2 (often searched as UACC OM MM 1G D 2) plugs directly into any SFP-equipped switch, access point, or network appliance in the Ubiquiti catalog without additional configuration. This direct-insertion design eliminates procurement complexity and deployment delay—no drivers, no firmware adjustments, no compatibility matrix consulting.
Key Features & Deployment Benefits
- 1 Gbps Multi-Mode Fiber Support: Handles 1 gigabit Ethernet throughput over standard multi-mode fiber (MMF), which is the norm in most campus and warehouse environments. Multi-mode fiber is cheaper and simpler to terminate than single-mode—a real advantage when you're running dozens of drops through existing conduit. The 1 Gbps bandwidth is sufficient for IP camera streams (typically 2–8 Mbps per camera in H.265), NVR backhaul, and inter-switch trunk traffic without congestion.
- SFP Form Factor: Fits into any standard SFP port on UniFi switches, controllers, gateways, or NVRs. The compact modular design means you swap transceivers without replacing entire hardware—useful when you need to upgrade fiber runs or extend a network to a new building. No rack space consumed; no separate line cards needed.
- Plug-and-Play Integration: No configuration required. Insert the module, and your UniFi equipment recognizes the fiber link immediately. This reduces deployment time significantly compared to managing separate fiber converters or managing heterogeneous transceiver types across a large system.
- Compact, Lightweight Design: Weighs 0.100 lb and takes up minimal shelf space. Ideal for integrators who stock spares or deploy multiple sites simultaneously. The small footprint also matters in dense switch installations where every port matters.
- Manufacturing to Specification: Built to Ubiquiti's quality standards in China, ensuring compatibility with UniFi ecosystem devices. Paired with Ubiquiti's reputation for consistency, this minimizes the risk of incompatibility surprises in the field.
- Medium-Distance Fiber Runs: Multi-mode fiber on 1 Gbps links typically supports distances up to 550 meters (1,800 feet) without signal degradation, depending on fiber grade. This covers most campus deployments and is well-suited for connecting distant camera arrays, secondary facilities, or warehouse zones to a central NVR or POE switch without active regeneration.
Integration & Compatibility
The UACC-OM-MM-1G-D-2 is compatible with the full Ubiquiti UniFi switch lineup and any network appliance equipped with an SFP port. This includes Dream Machine Pro, UniFi Dream Machine SE, UniFi Switch Pro series, and standard UniFi switches with SFP uplink ports. If your UniFi device has an SFP slot marked for fiber, this module will integrate without additional hardware or software.
Common deployment patterns include: (1) linking a remote camera building to a central NVR over a single fiber strand; (2) extending a warehouse floor network beyond copper PoE distance limits while keeping all IP camera feeds on the same logical network; (3) upgrading a campus backbone from copper to fiber for future-proofing and EMI immunity. In each case, the plug-and-play nature means the integrator focuses on fiber termination and routing, not on transceiver configuration.
When to Choose a Different Model
If your deployment requires single-mode fiber for long-haul runs (2+ km), consider Ubiquiti single-mode SFP modules in the same UACC family—they'll support longer distances but at higher termination cost. If you need higher throughput (10 Gbps), Ubiquiti offers 10G SFP+ transceivers; however, confirm your switch has SFP+ ports (not standard SFP) before specifying. For non-Ubiquiti networks, standard-compliant 1G MMF SFP transceivers from other vendors exist but may require separate validation against your existing switches.
Frequently Asked Questions
Q: What fiber types does the UACC-OM-MM-1G-D-2 support?
A: Multi-mode fiber (MMF), typically OM3 or OM4 grade. These are standard in campus and warehouse environments. Do not use with single-mode fiber; that requires a different transceiver module.
Q: Can I use this module with non-Ubiquiti SFP-equipped switches?
A: The UACC-OM-MM-1G-D-2 is designed for UniFi equipment. While it follows standard SFP specifications, compatibility with third-party switches is not guaranteed by Ubiquiti. Test in a lab before deploying in a critical environment.
Q: What is the maximum fiber run distance with this module?
A: Approximately 550 meters (1,800 feet) over multi-mode fiber at 1 Gbps, depending on fiber grade and light loss. Longer runs may require signal testing or regeneration.
Q: Is this module bidirectional (biDi)?
A: No, the UACC-OM-MM-1G-D-2 is a standard duplex transceiver requiring two fiber strands (Tx and Rx). Bidrectional modules are a separate product line and would be specified differently.
Q: Do I need any driver or firmware updates to use this module?
A: No. The module is plug-and-play. Insert it into an SFP port on any compatible UniFi device, and it operates immediately without additional configuration or software updates.
Q: What warranty does the UACC-OM-MM-1G-D-2 come with?
A: Refer to your Ubiquiti distributor or reseller for warranty terms. Standard Ubiquiti hardware typically carries a 1-year manufacturer warranty.

The UACC-OM-MM-1G-D-2 is a straightforward transceiver for UniFi shops that have already committed to the ecosystem and need to extend camera or NVR connectivity beyond practical copper distances. If you're managing a distributed warehouse or campus with multiple camera buildings 300+ meters apart, this module eliminates the cost and complexity of separate fiber converters or active optical equipment.
Technical Highlights:
- 1 Gbps duplex over multi-mode fiber: Sufficient headroom for concurrent IP camera streams plus control traffic. A typical 4MP camera at H.265 consumes 4–6 Mbps; you can easily stack 100+ cameras on a single 1 Gbps link without saturating the transceiver.
- ~550m reach on multi-mode: Covers most campus and warehouse deployments without regeneration. If your fiber run is longer, you'll need to specify single-mode and a different transceiver—plan your cabling audit accordingly.
- SFP form factor: Eliminates the need for external fiber-to-Ethernet media converters. You're not burning a switch port on a converter box; the transceiver is the converter, and it occupies only the SFP slot.
Deployment Considerations:
- Multi-mode fiber termination (LC or SC) is your responsibility—ensure your integrators are comfortable with field termination or budget for pre-terminated runs. Poor fiber prep will show up as signal loss and link flaps.
- If your upstream or downstream equipment is not UniFi (e.g., a Cisco switch), confirm SFP compatibility in writing before purchase. Ubiquiti doesn't publicly certify the UACC-OM-MM-1G-D-2 on third-party platforms, and standards compliance doesn't always translate to real-world interop.
- Keep a spare on hand for every 20+ deployments. Transceiver failure is rare, but a spare costs $30–50 and eliminates a return trip when a module eventually fails in the field.
The UACC-OM-MM-1G-D-2 is ideal for integrators standardizing on UniFi switching and looking to eliminate copper PoE range anxiety in large, geographically spread facilities. For homogeneous UniFi networks, it's a no-brainer. For mixed-vendor environments, validate first.
