Optical transceiver module CBO SFP28-25G-LR-BO 25 Gbps single-mode LR up to 10,000 m

CBO SFP28-25G-LR-BO is an SFP28 optical transceiver module that supports 25 Gbit/s data transmission over single-mode fiber. Engineered for LR (long reach) applications, the module offers a hot-pluggable form factor suitable for installation in compatible switches and routers. It is intended for single-mode links with a reach of up to 10,000 meters, delivering a standardized interface for high-speed uplinks, data center interconnects, and carrier network connections that require extended distance connectivity.

Advantages

The module provides a 25 Gbit/s data rate in a compact SFP28 package, enabling migration from 10G to 25G links without major infrastructure changes. Hot-pluggable design allows replacement or installation without powering down equipment. Designed for single-mode LR operation, it supports long-distance transmission up to 10,000 meters, reducing the need for intermediate regenerators or additional cabling segments. The standardized optical interface ensures interoperability with devices that accept SFP28 LR transceivers.

Suitable for

• 25 Gbps uplinks between switches and routers
• Data center interconnects over single-mode fiber
• Carrier and metro network links requiring long reach
• Server-to-switch connections in campus or enterprise networks

How to use

Install the transceiver into an SFP28-compatible port on a switch, router, or network interface card while the system is powered according to the equipment vendor’s hot-swap guidance. Connect single-mode fiber using the appropriate connector and ensure proper cleaning of fiber end faces before mating. Configure link settings on network devices as required for 25 Gbit/s operation and verify link status through device management interfaces. Follow any device-specific instructions for transceiver support and firmware compatibility.

Recommendations

Use single-mode fiber with appropriate attenuation budgeting for links approaching the maximum reach, and verify end-to-end optical power levels. Clean connectors before insertion and handle the transceiver by its housing to avoid contamination. Confirm compatibility with the host device’s transceiver acceptance list and update device firmware when necessary to ensure stable operation.
