Transceptor SFP28 CBO SFP28-25G-ESR-HU-BO 25 Gbit/s LC duplex, 300 m

CBO BlueOptics SFP28-25G-ESR-HU-BO is an optical SFP28 transceiver designed for 25 Gbit/s links over multimode or singlemode fiber with an LC duplex connector. The module supports a data rate of 25 Gbit/s and a nominal reach of up to 300 m, making it suitable for short-reach links in data center and enterprise network environments. Its compact, hot-pluggable SFP28 form factor allows straightforward installation and replacement in compatible switches, servers and network adapters.

Advantages

The transceiver offers a high-speed 25 Gbit/s interface in a small, industry-standard SFP28 package that supports hot-swapping for minimal downtime during maintenance. Its LC duplex connector ensures broad compatibility with standard fiber patching infrastructure. Built to provide reliable optical links up to 300 m, the module balances link distance and port density for data center top-of-rack and aggregation deployments.

Suitable for

• 25G Ethernet links between switches and servers in data centers
• Storage area network interconnects and network-attached storage (NAS) links
• Aggregation and spine connections in enterprise campus networks
• Scenarios requiring compact, hot-pluggable 25G optical uplinks

Key specifications

• Nominal data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 m over suitable fiber
• Form factor: SFP28, hot-pluggable
• Application: 25G Ethernet and short-reach optical links

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, server NIC or media converter while the device is powered according to vendor guidance, or hot-swap if the platform supports it. Connect LC duplex fiber patch cables observing correct transmit/receive polarity. Verify link status through the host device management interface and confirm correct speed and lane negotiation. If required, consult the network device documentation for any vendor-specific configuration or compatibility notes.

Recommendations

Ensure fiber type and cabling support the intended 300 m reach and that connectors are clean before installation. Use compatible SFP28-capable ports and keep firmware or driver versions up to date on host devices to maintain interoperability and stable 25G operation.
