SFP28 transceiver CBO SFP28-25G-ESR-FR-BO 25 Gbit/s LC 300 m

The CBO SFP28-25G-ESR-FR-BO is a compact SFP28 optical transceiver module that supports 25 Gbit/s data transmission over multimode or single-mode fiber with an LC duplex connector and a reach of up to 300 m. It is intended for use in 25G Ethernet and compatible high-speed links in switches, routers and customer edge/terminal equipment. The hot-pluggable form factor enables straightforward installation and replacement without powering down the host device.

Advantages

This SFP28 transceiver provides a standardized 25 Gbit/s interface in a small, industry-standard module, ensuring compatibility with a wide range of network devices that accept SFP28 ports. The LC connector and 300 m optical reach make it suitable for short to medium-distance links within data centers or campus networks. The hot-swappable design simplifies maintenance and upgrades, and the module’s optical operation reduces electromagnetic interference compared with copper alternatives.

Suitable for

• 25G Ethernet uplinks between switches and aggregation devices
• High-speed connections to routers and network appliances
• Server-to-switch links in data center topologies
• Campus backbone segments and inter-rack fiber runs up to 300 m

Key specifications

• Data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum optical reach: up to 300 m
• Form factor: SFP28 hot-pluggable module
• Application: 25G Ethernet and compatible serial optical links

How to use

Insert the SFP28 module into a compatible SFP28 port on the host device until it clicks into place, then secure any retention mechanism provided by the equipment. Connect LC duplex fiber patch cords observing correct transmit/receive orientation. Verify link status and speed via the host device management interface or LEDs. To remove the module, power down the link if required by your site procedures, disengage the retention latch and pull the module straight out of the cage. Follow your organization’s ESD precautions when handling the module and avoid touching the fiber endfaces.

Recommendations

Use factory-quality LC patch cords and maintain clean fiber connectors to ensure reliable 25G performance. Confirm compatibility with the host device firmware and port optics policy before deployment, and perform link testing after installation. Store unused modules in protective caps and anti-static packaging when not in use.
