Ubiquiti UACC-OM-SM-10G-S-2 10 Gbps Single-Mode SFP+ Transceiver
Overview
The Ubiquiti UACC-OM-SM-10G-S-2 is a single-mode SFP+ optical transceiver module engineered for long-distance 10 Gbps fiber connectivity within Ubiquiti UniFi networking infrastructure. Single-mode fiber carries data farther than multimode—typically 10 kilometers or more depending on wavelength and termination quality—making this module the right choice when you need to span campus networks, connect remote buildings, or bridge geographically dispersed data centers without intermediate repeaters or regenerators. If your fiber run is under 300 meters, multimode transceivers are cheaper and easier to terminate; beyond that, single-mode becomes practical.
This transceiver follows the industry-standard SFP+ (Small Form Factor Pluggable Plus) footprint, meaning it plugs directly into any compatible SFP+ port on Ubiquiti UniFi switches and routers without adapter plates or breakout cables. The UACC-OM-SM-10G-S-2 (often searched as UACC OM SM 10G S 2) works with UniFi switching equipment that includes SFP+ slots, streamlining campus fiber deployments across multiple sites.
Key Features
- 10 Gbps throughput: Delivers full wire-rate 10 Gigabit Ethernet performance, eliminating bottlenecks between core switches, storage arrays, or remote network segments. Ten gigabits is essential when aggregating multiple camera streams, high-bandwidth surveillance storage, or data center backups across fiber links.
- Single-mode fiber support: Works with single-mode optical cable (SMF-28 or equivalent), enabling transmission distances of 10+ km depending on the specific wavelength and cable condition. This eliminates costly intermediate regeneration equipment on longer runs.
- SFP+ form factor: Compact, hot-swappable module that plugs into any standard SFP+ port. No special enclosures, no proprietary slots—ports on modern Ubiquiti UniFi switches are universally compatible with this module.
- Bidirectional transmission: Supports two-way simultaneous data flow over a single fiber strand (wavelength-division multiplexing), cutting fiber infrastructure costs in half compared to unidirectional designs that require separate send/receive strands.
- Seamless UniFi integration: Recognized by UniFi Controller software for port monitoring and diagnostics. You manage optical link status, signal loss alerts, and transceiver temperature from the same dashboard where you configure your switches.
- Reliable long-distance deployments: Single-mode fiber is immune to modal dispersion, so distance-related signal degradation is minimal—critical when linking surveillance recording infrastructure, security operations centers, or warehouse automation networks across multiple geographic locations.
Integration & Compatibility
The UACC-OM-SM-10G-S-2 installs into any Ubiquiti UniFi networking switch or routing appliance equipped with an SFP+ port. Before deployment, verify your target device supports SFP+ (not SFP, which is different). Proper single-mode fiber termination—clean LC or SC connectors, correct polarity—is mandatory; misaligned or dirty connectors cause signal loss and link flapping. If you're new to fiber, allow time for termination testing and validation before going live on critical paths.
Pair this transceiver with single-mode fiber infrastructure and compatible termination hardware. Many installations use this module to bridge UniFi switches in separate buildings, merge surveillance networks across campuses, or connect redundant paths in enterprise network architectures.
Frequently Asked Questions
Q: Is the UACC-OM-SM-10G-S-2 compatible with non-Ubiquiti switches?
A: The module follows the standard SFP+ form factor and can physically insert into any SFP+ port. However, Ubiquiti has not published cross-compatibility certifications with other vendors' equipment. For production deployments outside the UniFi ecosystem, contact the switch manufacturer to confirm optical module support.
Q: What is the maximum fiber distance on this transceiver?
A: Single-mode SFP+ modules typically support 10 km or more. The exact distance depends on fiber condition, connector quality, and wavelength. Consult the detailed datasheet for specific attenuation values and distance tables for your installation.
Q: Do I need both ends of the fiber run to use the same transceiver model?
A: Yes. Both ends must use the same transceiver type (single-mode SFP+ in this case) and, ideally, the same model to ensure wavelength and protocol alignment. Mismatched transceivers can result in high error rates or link failure.
Q: Can this module work with multimode fiber?
A: No. Single-mode transceivers are not compatible with multimode fiber. Attempting to connect single-mode and multimode strands causes significant signal loss and link failure.
Q: What is the warranty on the UACC-OM-SM-10G-S-2?
A: Refer to the Ubiquiti product documentation or contact your distributor for current warranty terms. Transceiver modules typically carry a 1-year limited warranty covering manufacturing defects.
Q: Is this transceiver hot-swappable?
A: Yes. SFP+ modules can be inserted and removed without powering down the switch. However, removing or inserting a transceiver while an active link is running will interrupt traffic on that port. Coordinate maintenance windows accordingly.

The UACC-OM-SM-10G-S-2 is the right module when you're building long-haul UniFi fiber links—think multi-building campuses, remote data centers, or geographically separated surveillance recording facilities. Single-mode transceivers cost more upfront than multimode, but the 10+ km range eliminates repeaters and regeneration gear that would otherwise multiply your infrastructure footprint and operational complexity. This module delivers bidirectional transmission over a single fiber strand, so you're not burning two strands per link—a meaningful cost saving on new fiber runs.
Technical Highlights:
- 10 Gbps bidirectional throughput: Full wire-rate performance means no link-speed negotiation or asymmetry issues. You get consistent 10G in both directions, essential when aggregating multiple high-bitrate surveillance cameras or synchronizing disaster-recovery storage across sites.
- Single-mode, 10+ km reach: Eliminates intermediate regenerators on campus links longer than a few hundred meters. If you're bridging buildings two kilometers apart, this module pays for itself versus multimode transceivers that would require repeaters at 300m intervals.
- Hot-swappable SFP+ form factor: Plug-and-play insertion into UniFi switches without enclosure modifications. Fiber termination is the only skill gate—assuming your connectors are clean and polarity-correct, integration is straightforward.
Deployment Considerations:
- Single-mode fiber termination demands discipline: dirty LC/SC connectors or polarity mismatches will kill your link or cause intermittent flapping. Budget time for fiber inspection and cleaning before going live.
- Verify your target UniFi switch has SFP+ ports (not SFP—the older 1G standard). Check the device datasheet; some lower-end UniFi models ship with Gigabit Ethernet only.
- Use the same transceiver model on both ends of the link. Mixing UACC-OM-SM-10G-S-2 with a different vendor's single-mode SFP+ introduces wavelength and protocol risk; stick to matched pairs for production.
This module is purpose-built for high-availability surveillance or data center networks that span real geographic distance. If all your sites are within 300 meters, multimode is cheaper and easier to manage. Beyond that, the UACC-OM-SM-10G-S-2 is the smart infrastructure choice for UniFi-based enterprise deployments.
