CBO Transceiver SFP28-25G-LR Allied Telesis 25Gbps LR Fiber Optic Module

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.

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.
