## Long description

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.
