Double Your Bandwidth, Halve Your Cables: The BiDi Principle
The Ubiquiti UACC-OM-SM-10G-S-2 is more than just an SFP+ Transceiver – it's your gateway to a more efficient Network world. The magic lies in BiDi (bidirectional) technology. Instead of requiring two fiber optic cables for sending and receiving, this SFP / SFP+ Module pair uses different wavelengths (1270 nm and 1330 nm) to transmit both signals over a single fiber. The result? You halve your Cabling costs and massively simplify your infrastructure. Ideal if you want to optimize existing lines or double your Network capacity without extensive new installations.
Stable 10 Gbps Performance for your UniFi Network
No more compromising on speed. This module pair provides you with a rock-solid 10 Gbps connection over an impressive distance of up to 10 kilometers. Whether you want to connect two buildings on a campus, link your data center to a distribution point, or simply network a floor with the server room – the UACC-OM-SM-10G-S-2 ensures maximum Network performance. As part of the Ubiquiti ecosystem, it is naturally perfectly matched to devices like the UniFi Switch, but also works in any other device with a compatible SFP+ port.
Full Control Thanks to Digital Diagnostics Monitoring (DDM)
As a Network professional, you know that transparency is key to stability. That's why these SFP / SFP\+ Modules are equipped with DDM (also called DOM). This function gives you real-time insight into critical operating parameters directly in your switch's interface. Monitor temperature, optical transmit and receive power, and laser bias current. This allows you to identify potential problems before they lead to an outage, enabling proactive maintenance of your Network.
Installation and Compatibility: What You Need to Know
Installation is straightforward: The SFP / SFP\+ Modules are hot-pluggable and can be inserted during operation. However, strict pairing is important: one module of the pair must be installed at one end of the fiber and the complementary counterpart at the other end. A mix-up will inevitably lead to a link failure and requires careful planning. The modules are also backward compatible and can be operated in a 1G SFP port, with the speed then limited to 1 Gbps. For full performance, an SFP+ port is required.
Strengths & Notes at a Glance
- Pro: Halves the need for fiber optic cables, significantly reducing infrastructure and Cabling costs.
- Pro: Allows doubling the connection capacity on existing single fiber optic lines.
- Pro: Offers a long range of up to 10 km at full 10 Gbps speed.
- Pro: DDM/DOM function allows real-time monitoring for proactive maintenance and quick fault diagnosis.
- Note: The SFP / SFP\+ Modules must be used as a complementary pair; an incorrect combination will prevent the connection.
- Note: Compatibility issues may arise when connecting with third-party devices, requiring manual port configuration.

Frequently Asked Questions (FAQ)
Do the UACC-OM-SM-10G-S-2 modules always have to be purchased and used in pairs?
Yes, this is mandatory. As these are bidirectional (BiDi) transceivers, they utilize different wavelengths for sending and receiving over a single fiber, crucial for any Network setup. One SFP / SFP+ Module transmits at 1270 nm and receives at 1330 nm, while its counterpart transmits at 1330 nm and receives at 1270 nm. Without this complementary pair, no connection can be established.
Can I use this SFP+ module in a regular SFP port?
Yes, the SFP / SFP+ Module is backward compatible and can be operated in an SFP port. However, the negotiated speed will then be limited to 1 GBit/s. To utilize the full 10 GBit/s performance, it must be plugged into an SFP+ port of a compatible device.
What does 'Simplex LC Connector' mean?
'Simplex' means that only a single optical fiber is required for the connection, in contrast to 'Duplex' where two fibers are needed. 'LC' (Lucent Connector) describes the small, square form factor of the physical connector that plugs into the SFP / SFP+ Module, part of the essential Cabling.
Why am I not getting a connection, even though everything seems correctly connected?
The most common causes are: 1. The SFP / SFP+ Modules at both ends are not the correct, complementary pair. 2. The fiber optic Cabling itself is damaged, severely bent, or the connectors are dirty. 3. There is a compatibility issue with the Ethernet Switch, or the port speed is fixed and not set to auto-negotiation.
Is the fiber optic cable included?
No, the fiber optic Cabling is not included. You need to purchase a separate Single-Mode Fiber (SMF) cable with Simplex LC connectors, designed for the required distance to complement your SFP / SFP+ Modules.
What is the difference between this single-mode module and a multi-mode module?
Single-mode SFP / SFP+ Modules like this one use a laser with a narrower wavelength and are designed for long-distance Network connections up to 10 km. Multi-mode modules are intended for shorter distances, typically up to 500 meters, and use different fiber types that are not compatible.
