SFP28 optical transceiver CBO SFP28-25G-ESR-QN-BO 25 Gbps LC 300 m

CBO SFP28-25G-ESR-QN-BO is a 25 Gbps SFP28 optical transceiver with an LC duplex connector and a maximum reach of 300 m over multimode fibre. The module provides single-lane 25G data connectivity in a hot-pluggable SFP28 form factor, suitable for installation in switches, routers and network interface cards. It is designed for data centre and enterprise networks requiring compact, high-speed uplinks and server connections.

Advantages

The SFP28 transceiver supports single-lane 25 Gbps operation while maintaining compatibility with standard SFP28 ports, allowing simple upgrades from lower-speed modules. Its hot-pluggable design enables tool-free replacement and minimal service interruption. With an LC duplex interface and a 300 m reach on multimode fibre, the module covers typical short-reach trunking and server connectivity use cases in racks and data halls. The compact size reduces port density impact while delivering point-to-point 25G bandwidth.

Suitable for

• 25G uplinks between switches and aggregation points
• Server to top-of-rack switch connections
• High-speed links in enterprise LAN and campus networks
• Data centre leaf-spine fabrics with short-reach multimode fibre

Key specifications

• Data rate: 25 Gbps (single lane)
• Connector type: LC duplex
• Maximum reach: up to 300 m over multimode fibre
• Form factor: SFP28, hot-pluggable
• Application: short-reach data centre and enterprise links

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on switches, routers or network interface cards until it latches, then attach LC duplex multimode fibre patch cords. Ensure the host device port is configured for 25G operation and that the fibre type and patch cords match the module's multimode specification. Remove power or use hot-swap procedures per equipment guidance if the platform requires it; the module is designed for hot-pluggable replacement to minimize downtime.

Recommendations

For reliable performance, use OM3/OM4 multimode fibre and quality LC patch cords, verify transceiver compatibility with the host vendor's supported module list, and observe ESD precautions during handling. Monitor link status and SFP diagnostics via the host system to confirm proper optical power and temperature ranges.
