## Summary description

MicroOptics UF-SM-1G-S is an SFP fiber optic transceiver module supporting up to 1250 Mbit/s with a 1550 nm wavelength. Supplied as a set of 2 modules, it provides single-mode bidirectional connectivity for network devices with SFP ports. Typical use cases include fiber uplinks between switches, routers or media converters over long-distance links.

## Long description

Ubiquiti UF-SM-1G-S is a single-mode SFP fiber transceiver module designed for 1 Gbit/s (1250 Mbit/s) links over long-distance fiber. The module fits standard SFP slots and is offered in a two-piece set. It uses 1550 nm optics and is intended for outdoor fiber deployments where single-mode performance is required.
Advantages
The UF-SM-1G-S provides single-mode connectivity suitable for long runs, supporting typical SFP form-factor compatibility and a 1250 Mbit/s data rate. Its compact SFP interface makes it compatible with a wide range of switches and routers that accept SFP transceivers, and the product comes in a two-piece set for establishing a pair link.
Suitable for
Long-distance fiber links (single-mode) between buildings or towers
Outdoor fiber installations requiring SFP transceivers
Network equipment with standard SFP interfaces that require 1 Gbit/s optics
When it may not be suitable
This single-mode SFP is not the right choice for short-distance multimode fiber runs; multimode SFP modules are more cost-effective and appropriate for that use. It also does not provide multi-rate 10G operation—if 10 Gbit/s is required, a different transceiver type is needed.
Key specifications
Form factor: SFP (small form-factor pluggable)
Optical type: single-mode fiber
Wavelength: 1550 nm
Maximum data rate: 1250 Mbit/s (1 Gbit/s)
Typical use: long-distance fiber links
Package quantity: 2 pieces
Product colours: aluminium, blue, yellow
How to use
Insert the UF-SM-1G-S module into an SFP slot on compatible network equipment following the device manufacturer’s hot-swap guidelines. Connect single-mode LC fiber cables to the module using appropriate connectors and ensure proper polarity. Configure the network interfaces on your switches or routers to enable the 1 Gbit/s link and verify the optical signal and link status before putting the connection into production.
What to consider before purchase
Ensure target equipment accepts third-party SFP modules and supports 1 Gbit/s SFP optics
Confirm you require single-mode 1550 nm optics rather than multimode transceivers
Verify the required link distance and fiber type are compatible with single-mode SFP performance
Usage recommendations
For long outdoor runs of 300+ meters or where reusing existing single-mode infrastructure is important, use single-mode UF-SM-1G-S modules. For shorter multimode connections, choose multimode 1G modules to reduce cost. Use quality single-mode LC cables and test the link after installation to confirm signal levels and polarity.
