UniFi OM4 Duplex LC UPC Fiber Patch Cable

The Ubiquiti UniFi OM4 Duplex LC UPC Fiber Patch Cable (UACC-OFC-M2-LULU) is an indoor multi-mode fiber patch cable for short, low-loss links between UniFi optical modules. With ≤ 0.3 dB insertion loss, a slim 2 mm LSZH jacket and seven lengths from 0.5 m to 30 m, it is a clean, repeatable way to patch 10G and 25G fiber ports across a UniFi network.

Key features

• OM4 multi-mode fiber, 850/1300 nm – Matched to UniFi multi-mode optics. The UniFi 25G Multi-Mode Optical Module supports 1, 10 and 25 Gbps over OM4 fiber at up to 100 m.
• Duplex LC UPC connectors at both ends – The same connector type fitted to UniFi multi-mode optical modules, so it plugs straight in.
• Low-loss, consistent optics – Insertion loss ≤ 0.3 dB, return loss ≥ 35 dB and repeatability ≤ 0.1 dB keep your link budget healthy.
• Built for re-patching – Durability rated at ≤ 0.2 dB after 1,000 mating cycles.
• 2 mm LSZH jacket – Low smoke zero halogen material for indoor spaces; the slim diameter keeps dense patch panels tidy.
• Rose jacket for instant identification – Easy to tell apart from Ubiquiti's yellow OS2 single-mode patch cables.
• Seven lengths, single or 50-pack – 0.5, 1, 3, 5, 10, 15 and 30 m; 50-packs available in 0.5, 1 and 3 m.
• Wide operating range – -40 to 75 °C (-40 to 167 °F) ambient operating temperature.

Made for UniFi multi-mode fiber links

Ubiquiti's OM4 Duplex LC UPC Fiber Patch Cable is the multi-mode option in the UniFi fiber accessory range. It terminates in duplex LC UPC connectors at both ends, the connector type fitted to UniFi multi-mode optical modules, and is specified for 850/1300 nm wavelengths. Pair it with the UniFi 25G Multi-Mode Optical Module (UACC-OM-SFP28-SR), which fits SFP, SFP+ and SFP28 interfaces and supports 1, 10 and 25 Gbps over OM4 fiber at distances up to 100 m. Ubiquiti's optical modules do not include a fiber cable, so this is the part to add to the order.

Low loss you can rely on, patch after patch

Each connector is specified for ≤ 0.3 dB insertion loss and ≥ 35 dB return loss, with ≤ 0.1 dB repeatability between connections. Durability is rated at ≤ 0.2 dB after 1,000 mating cycles, so performance holds up through rack moves, lab reshuffles and routine re-patching rather than only on day one.

A jacket designed for indoor installs

The 2 mm (0.08") low smoke zero halogen (LSZH) jacket suits enclosed indoor environments such as comms rooms and equipment racks, and its slim profile makes it easier to route through high-density patch panels. The rose colour distinguishes OM4 multi-mode runs from Ubiquiti's yellow OS2 single-mode patch cables at a glance. The cable is rated for an ambient operating temperature of -40 to 75 °C (-40 to 167 °F) and is specified for indoor operating environments.

The right length, in the right quantity

Choose from 0.5, 1, 3, 5, 10, 15 or 30 m (1.6 to 98.4 ft). For larger rollouts, the 0.5 m, 1 m and 3 m lengths are also sold in 50-packs, so you can standardise on one Ubiquiti-branded patch cable across every rack.

Lengths and ordering options

Part-number note: the Ubiquiti store shows per-length part numbers in the form UACC-OFC-M2-LULU-0.5M (the 0.5 m variant). The official pages do not display the 50-pack part numbers, so confirm those against your distributor feed before publishing.

Compatibility and related UniFi products

• UniFi 25G Multi-Mode Optical Module (UACC-OM-SFP28-SR) – SFP28 transceiver with a duplex LC UPC connector, 850 nm TX/RX, 1/10/25 Gbps, OM4 reach up to 100 m (OM3 up to 70 m). Ubiquiti's store also lists 1G and 10G variants in the same multi-mode module family. Fiber cable is not included with the module.
• UniFi OS2 Duplex LC UPC Fiber Patch Cable (UACC-OFC-S2-LULU) – The single-mode counterpart: OS2 fiber, yellow LSZH jacket, 1310/1550 nm, same length and pack options. Choose this for single-mode optics instead.
• OM4 MPO-12 UPC variant – Offered on the same Ubiquiti product page for optics that use MPO-12 connectors rather than duplex LC.
