Ubiquiti U-Fiber UF-SM-1G-S SFP/SFP+ Module (2 Pack) Features
The Ubiquiti U-Fiber UF-SM-1G-S SFP/SFP+ Module allows you to upgrade or expand specific Ubiquiti switches for faster network operations. This Gigabit SFP Transceiver Module kit is compatible with all Ubiquiti products that support the UF-SM-1G-S SFP Transceiver.

Ubiquiti U-Fiber UF-SM-1G-S Key Features
- TX Wavelength Blue 1310 nm Yellow 1550 nm
- RX Wavelength Blue 1550 nm Yellow 1310 nm
- Data Rate 1.25 Gbps SFP
- Cable Distance 3 km
- UACC-OM-SM-1G-S-2


Outdoor Use
For long-distance single-mode runs, use the UF-SM-1G-S for distances of up to 3 km at 1 Gbps. To protect DC power and fiber, deploy EdgePoint with EdgePower.
Deploy a BiDi (BiDirectional) model, UF-SM-1G-S, to maximise re-use of existing infrastructure. You must deploy a BiDi model as a paired set of modules because the pair uses two different wavelengths, upstream and downstream, on a single fiber.

Indoor Runs
For convenient multi-mode connections that extend beyond the 100-meter limitation of Ethernet cabling, use the UF-MM-10G for distances of up to 300 m and speeds of up to 10 Gbps, or use the UF-MM-1G for distances of up to 550m and speeds of up to 1 Gbps.
Outdoor Use
For long-distance single-mode runs, use the UF-SM-10G for distances of up to 10 km at 10 Gbps, or use the UF-SM-1G for distances of up to 3km at 1 Gbps. To protect DC power and fiber, deploy EdgePoint™ with EdgePower™.
Deploy a BiDi (BiDirectional) model, UF-SM-1G-S or UF-SM-10G-S, to maximize re-use of existing infrastructure. You must deploy a BiDi model as a paired set of modules because the pair uses two different wavelengths, upstream and downstream, on a single fiber.
