## Long description

The CBO Transceiver SFP28-25G-LR Allied Telesis 25Gbps LR Fiber Optic Module is a single-port optical transceiver designed for long-reach single-mode fiber connections. Compatible with Allied Telesis equipment and branded by BlueOptics, this SFP28 module supports 25 Gbps data rates and is intended for reliable high-speed links between switches, routers and data center systems. It is suitable for extending network reach while maintaining low-latency performance for enterprise and service provider networks.
Advantages
The module provides 25 Gbps throughput over long-reach single-mode fiber, enabling higher bandwidth without replacing existing fiber infrastructure. Its single-port SFP28 form factor allows straightforward installation into compatible transceiver bays and supports hot-swap replacement. The transceiver is engineered for stable optical performance and low power consumption, helping to preserve system efficiency and minimize thermal impact in rack-mounted equipment.
Suitable for
25 Gbps uplinks between switches and aggregation devices
Data center interconnects over single-mode fiber
Long-reach links in campus and metropolitan networks
Upgrading or replacing 25G LR ports in Allied Telesis systems
Key specifications
Form factor: SFP28 single-port optical transceiver
Nominal data rate: 25 Gbps
Optical reach: long-reach single-mode fiber (LR)
Connector type: LC duplex
Transmission wavelength: typical single-mode laser wavelength for LR optics
Power consumption: low-power SFP28 class
Operating temperature: industrial/commercial ranges compatible with network equipment
How to use
Install the SFP28-LR transceiver into a compatible SFP28 slot on Allied Telesis switches or other supported equipment with the LC connector facing outwards. Ensure the device is powered and the slot supports 25 Gbps LR optics before insertion. Connect the LC-duplex single-mode fiber cable, verify link status via the equipment management interface, and monitor optical parameters to confirm proper operation. For replacement, remove the existing transceiver with standard ESD precautions and insert the new module while the system remains powered if the chassis supports hot-swap transceivers.
Usage recommendations
Use single-mode LC duplex fiber with appropriate launch power and attenuation for LR links. Verify compatibility with the host device firmware and check optical budget requirements for the desired link distance. Handle the transceiver with ESD protection and keep optical connectors clean to ensure expected performance and longevity.
