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

CBO SFP28-25G-ESR-AO-BO is a compact SFP28 optical transceiver module designed for 25 Gbit/s short-reach fiber connections. The module uses an LC duplex connector and supports a link distance of up to 300 meters over single-mode or specified multimode fiber, making it suitable for high-speed Ethernet links, data center interconnects and server-to-switch connections. The hot-pluggable form factor allows straightforward installation into compatible SFP28 ports with low insertion effort and reliable electrical and optical performance.

Advantages

The module delivers a stable 25 Gbit/s data rate with low latency and predictable signal quality. Its LC duplex interface provides a standard fiber connection for easy integration into existing cabling infrastructure. The small SFP28 package ensures compatibility with high-density switch and server platforms while enabling hot-swapping without system downtime. Built-in optical features ensure consistent reach up to 300 meters under specified fiber conditions.

Suitable for

• 25 Gigabit Ethernet links in data centers
• Server-to-switch and switch-to-switch short-reach connections
• High-performance computing clusters and storage networks
• Top-of-rack (ToR) connectivity in dense rack environments

Key specifications

• Data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 m (fiber dependent)
• Form factor: SFP28, hot-pluggable
• Optical interface: duplex fiber
• Typical use: short-reach multimode/single-mode fiber links

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, server or network interface card until it clicks into place. Connect LC duplex patch cables to the transceiver, observing correct transmit/receive orientation. Ensure proper fiber type and link budget for the intended 300 m reach and verify link status through the host device management interface. For removal, disengage any retention latch and carefully pull the module straight out to avoid damaging the port.

Recommendations

Use manufacturer-recommended LC duplex cables and maintain clean fiber connectors to ensure optical performance. Verify compatibility with the host device and confirm supported link modes before deployment. Avoid excessive bending or mechanical stress on fiber cables and follow standard electrostatic discharge precautions when handling the transceiver.
