SFP28 transceiver CBO SFP28-25G-LR-QN-BO 25 Gbit/s LC single-mode 10,000 m

The CBO SFP28-25G-LR-QN-BO is a 25 Gbit/s SFP28 optical transceiver designed for long-reach single-mode fiber links. With an LC duplex interface and support for distances up to 10,000 meters, this module fits standard SFP28 cages and compatible network devices. It is intended for use in high-speed Ethernet environments and optical uplinks where reliable, low-latency transmission and straightforward, hot-pluggable installation are required.

Advantages

This SFP28 transceiver provides a 25 Gbit/s data rate over single-mode fiber with a long reach of up to 10 km, enabling extended link distances without intermediate amplifiers. The LC connector ensures wide compatibility with common fiber patching infrastructure, while the standard SFP28 form factor supports easy installation and module replacement in switches and routers. The module’s design focuses on stable optical performance and interoperability with data center and enterprise network equipment.

Suitable for

• 25 Gigabit Ethernet uplinks between switches and aggregation devices
• Long-distance single-mode connections in campus and data center environments
• Optical backbone links and inter-rack or inter-building connectivity
• Upgrading existing SFP28-capable network ports to 25 Gbit/s

Key specifications

• Data rate: 25 Gbit/s
• Fiber type: single-mode
• Connector: LC duplex
• Maximum reach: 10,000 meters (10 km)
• Form factor: SFP28 (hot-pluggable)
• Application: 25G Ethernet, optical uplinks

How to use

Install the module into an SFP28-compatible port on a switch, router or transceiver-equipped device while the host system is powered on or according to the device vendor’s hot-swap guidance. Connect single-mode LC patch cords to the transmit and receive ports, observing proper fiber cleanliness and polarity. Verify link status through the network device management interface and confirm 25 Gbit/s operation and optical power levels with device diagnostics or monitoring tools.

Recommendations

Use high-quality single-mode LC patch cords and keep connector endfaces clean to maintain signal integrity. Check compatibility with the host device’s supported transceiver list and monitor optical power and temperature parameters to ensure stable long-reach operation.
