Ubiquiti UACC-OFC-MM-0.5M OM3 Duplex LC Fiber Cable
Overview
The Ubiquiti UACC-OFC-MM-0.5M is a 0.5-meter OM3 multimode duplex fiber optic cable with LC connectors, engineered for short-run optical interconnects in enterprise network and data center environments. This cable bridges distances where copper becomes bulky or electromagnetically problematic—between rack-mounted network switches, optical transceivers, or distribution panels without requiring dedicated conduit or grounding considerations. The 0.5-meter length eliminates slack in tight spaces while maintaining signal integrity at rates up to 10 Gbps.
Key Features
- OM3 Multimode Fiber: OM3 supports bandwidth-distance products up to 2,000 MHz·km, meaning you can run 10 Gbps reliably over this 0.5-meter patch without attenuation concerns. For comparison, OM2 fiber would be marginal at these speeds; OM3 is the practical floor for modern data center links.
- Duplex Configuration: Both transmit and receive paths are bundled in a single jacket, reducing cable clutter behind equipment and lowering per-connection footprint in congested panel layouts.
- LC Connectors: LC (Lucent Connector) is the de facto standard in modern data centers and carrier-grade equipment racks. It's smaller than SC, allowing denser packing on patch panels and transceiver modules without crosstalk or insertion-loss drift.
- 9–10 Gbps Throughput: Tested for sustained 10 Gbps operation—sufficient for Gigabit Ethernet uplinks, SFP+ transceiver pairs, or emerging 10 Gigabit Ethernet (10GbE) backbone segments. If you're planning future 25 Gbps or 40 Gbps infrastructure, verify transceiver compatibility rather than assuming the cable is the limiting factor.
- Compact 0.5-Meter Length: Eliminates coil-up and cable management headaches in server-to-switch or switch-to-distribution scenarios. No need to anchor loops or manage excess slack that wastes rack space or creates airflow obstructions.
- Cost-Effective Multimode: OM3 is significantly cheaper than single-mode fiber (SMF) yet supports distances and data rates that eliminate copper Ethernet runs in many architectures. If your link is under 100 meters and speed is 10 Gbps or less, multimode is the economical choice.
Integration & Compatibility
The UACC-OFC-MM-0.5M integrates with any optical transceiver, switch port, or patch panel equipped with standard LC duplex connectors. Ubiquiti's optical equipment (including their carrier-grade switches and distribution units) and most third-party SFP+ or SFP28 transceivers accept this connector type. Confirm your receiving equipment supports OM3 multimode wavelengths (typically 850 nm for short-reach Ethernet)—single-mode equipment requires a different fiber type and will not function interchangeably.
This cable is also compatible with generic LC-patch-panel infrastructure, making it a drop-in replacement if you're standardizing on Ubiquiti or migrating existing multimode fiber runs to newer bandwidth profiles.
When to Choose a Different Model
If your link distance exceeds 300 meters, consider a longer OM3 variant or transition to single-mode fiber for metro or campus runs. If you need higher density (smaller form factor), some vendors offer MTP/MPO breakout cables; Ubiquiti's accessory line should include those alternatives if density is a constraint. For runs requiring future 40 Gbps or 100 Gbps, verify that OM3 meets your modal-dispersion budget; single-mode fiber is preferred for next-generation speed classes.
Frequently Asked Questions
Q: Can I use the UACC-OFC-MM-0.5M with single-mode transceivers?
A: No. Single-mode transceivers operate at different wavelengths (typically 1310 nm or 1550 nm) and have different chromatic-dispersion profiles. OM3 multimode fiber (850 nm) will not align with single-mode optics and will result in no signal or severe signal degradation. Verify your equipment supports multimode before ordering.
Q: What is the difference between OM3 and OM2 fiber?
A: OM3 supports higher bandwidth-distance products (2,000 MHz·km vs. OM2's 500 MHz·km), allowing longer runs at 10 Gbps. For the UACC-OFC-MM-0.5M's short 0.5-meter length, both OM2 and OM3 will pass 10 Gbps traffic; however, OM3 is more future-proof and standard in modern deployments.
Q: Is this cable shielded or grounded?
A: Fiber optic cables are immune to electromagnetic interference by nature—no shielding or grounding is required. This is one of fiber's primary advantages over copper in RF-heavy or high-EMI environments.
Q: What should I do with excess cable length if my run is shorter than 0.5 meters?
A: At 0.5 meters, there is minimal slack; if your transceiver-to-transceiver distance is less than 0.5 meters, you may have a few inches of coil or drape. Keep bend radius above 10 cm (4 inches) to avoid microbending losses. If precise length is critical, contact your vendor about custom cut lengths.
Q: Does the UACC-OFC-MM-0.5M support backward compatibility with older 1 Gbps Ethernet?
A: Yes. OM3 multimode fiber supports any speed from 100 Mbps to 10 Gbps on the same fiber. Backward compatibility is guaranteed; you can use this cable with older 1 GbE SFP transceivers without issue.

The UACC-OFC-MM-0.5M (often searched as UACC OFC MM 0.5M) is a no-fuss optical patch cable for exactly one job: linking high-speed transceivers or optical modules in racks where copper runs have become either too bulky or electromagnetically problematic. At 0.5 meters, it's engineered for the equipment-to-equipment distances you actually encounter—not the 2-meter or 3-meter commodity cables that force you to manage slack in tight spaces.
Technical Highlights:
- 10 Gbps Sustained Throughput: OM3 fiber rated for 2,000 MHz·km bandwidth-distance, guaranteeing zero attenuation headroom over this short 0.5-meter run. You're not bandwidth-limited by the cable; you're limited only by transceiver capabilities and switch port speed.
- LC Duplex Connectors: The industry standard for dense patch-panel deployments. LC footprint is roughly 50% smaller than SC, meaning you fit more connections per U of rack space without crosstalk or insertion-loss creep from repeated mating cycles.
- Multimode Cost Advantage: OM3 transceivers are 30–50% cheaper than equivalent single-mode modules, and the fiber itself is a fraction of the cost of SMF. If your run is under 300 meters and speed is 10 Gbps or less, multimode is the defensible economic choice.
Deployment Considerations:
- Bend radius matters: keep the cable above 10 cm (4 inches) when routing behind panels or through cable trays. Tighter bends introduce microbending losses that degrade signal quality, especially at higher speeds.
- Verify transceiver type before order. If your equipment uses single-mode optics, this cable will not work—no fallback, no crossover possible. Confirm 850 nm multimode support in your switch or transceiver datasheet.
The UACC-OFC-MM-0.5M is best suited for short-haul data center interconnects—switch-to-storage, switch-to-optical-distribution, or backbone segments where copper becomes unwieldy and single-mode fiber is overkill. It's not a future-proofing cable for 40 Gbps or 100 Gbps; if that's on the roadmap, single-mode or higher-density MTP breakouts are the better long-term play.
