CBO SFP28-25G-ESR-SP-BO SFP28 25 Gbit/s optický transceiver, LC, 300 m

The CBO SFP28-25G-ESR-SP-BO is a single-port SFP28 optical transceiver supporting a 25 Gbit/s data rate with an LC duplex connector and a link reach of up to 300 m. Designed for high-speed Ethernet and data centre interconnects, this compact pluggable module delivers short-reach optical connectivity for switch-to-switch links, server uplinks and aggregation layers. The module is suitable for environments where space, power efficiency and stable 25 G connectivity are required.

Advantages

This SFP28 transceiver provides a standardized, hot-pluggable form factor that is compatible with a wide range of 25 Gbit/s ports. It supports reliable short-reach optical links with an LC duplex connector and a reach up to 300 m, reducing the need for expensive cabling alternatives for nearby racks or buildings. The compact design conserves slot space in network equipment, while the optical interface reduces electromagnetic interference compared with copper solutions. The module is appropriate for dense data centre deployments and edge aggregation.

Suitable for

• 25 Gbit/s Ethernet switch-to-switch connections
• Server uplinks and top-of-rack aggregation
• Data centre short-reach interconnects up to 300 m
• Environments requiring LC duplex optical connections

Key specifications

• Data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 m (short-reach optical link)
• Form factor: SFP28 hot-pluggable module
• Application: high-speed Ethernet and data centre interconnects

How to use

Install the SFP28 module into a compatible 25 Gbit/s SFP28 slot on switches, servers or optical equipment while the host is powered off or following vendor hot-swap guidelines. Connect LC duplex fiber patch cables matching the required single-mode or multimode fiber type as specified by your network design. Verify link negotiation and port settings on the host device, and monitor interface status through standard network management tools. Replace or reseat the module if a fault is detected following the equipment manufacturer's troubleshooting procedures.

Recommendations

Use high-quality LC duplex fiber patch cords and follow your equipment vendor's compatibility list to ensure reliable 25 Gbit/s operation. Keep fiber connectors clean and protected with dust caps when not in use, and ensure proper cooling and airflow within network racks to maintain transceiver performance.
