The UBIQUITI NETWORKS SFP28 transceiver with manufacturer number UACC-OM-SFP28-LR is an optical network module for high-speed connections over single-mode fiber. It serves as an interface module for switches and routers to establish 25-Gigabit-Ethernet connections over distances up to 10 km. The module is specifically designed for use in professional network infrastructures where high data rates and stable connections over long distances are required.

Applications
This module is suitable for backbone connections in corporate networks, data centers, or for linking network segments over greater distances. It is used in environments where fiber optic cables are the only option for transmitting 25 Gbit/s over more than several hundred meters. The use of single-mode fiber enables high bandwidth and low attenuation, which is crucial for long-distance, reliable data transmission.

Features and Equipment in Detail
The transceiver supports a maximum data rate of 25 Gbit/s and is designed for operation in SFP28 interfaces. It is also compatible with SFP+ and SFP ports, enabling flexible use in existing networks. The connection is made via a duplex LC-UPC connector, which is standard for single-mode fiber cables. The UPC end-face (Ultra Physical Contact) ensures optimal light transmission and minimizes reflections at the fiber edge.

Technology Explained Simply
The module uses SFP28 technology, which represents a compact form factor standardization for high-speed network modules. The term SFP28 stands for Small Form-factor Pluggable 28, where the number 28 refers to the data rate of 25 Gbit/s. Transmission occurs over single-mode fiber, where a single light mode is guided through the fiber, enabling low attenuation and high reach. The maximum reach of 10 km is achieved under standard conditions, with the actual distance depending on the quality of the fiber cable and optical performance.

Compatibility and Accessories
The module is designed for SFP28, SFP+, and SFP interfaces, allowing use in a wide range of network devices. However, it is not compatible with other module form factors such as QSFP or XFP. The connection must be set up according to the requirements of the network topology and fiber quality.

Installation and Mounting
Installation is done by simply inserting the module into the corresponding port of a switch or router. It is important that the port supports the required interface (SFP28, SFP+, or SFP). After insertion, the module is automatically detected and initialized. The connection to the fiber cable is made via the integrated LC connector, with clean and correct fiber end preparation ensuring no signal loss occurs.

Advantages in Operation
The use of this module enables a scalable network architecture, allowing 25-Gigabit connections over long distances. Compatibility with various SFP form factors increases flexibility in device selection. The use of single-mode fiber ensures high signal quality and minimal attenuation, guaranteeing reliable connections over 10 km. The module is designed for use in professional networks where stability and performance are paramount.
