SFP28 Transceiver CBO SFP28-25G-LR 25G 1310nm single‑mode LC

The CBO SFP28-25G-LR is a 25 Gigabit SFP28 optical transceiver designed for single‑mode fiber links using an LC connector and a 1310 nm wavelength. Engineered for 25G Ethernet and other high‑speed serial interfaces, this small form‑factor module fits SFP28 slots and enables reliable short‑reach single‑mode transmission between switches, servers and aggregation equipment in data center and enterprise networks.

Advantages

This SFP28 transceiver offers compact size and low power consumption suited to high‑density installations. The 1310 nm single‑mode design delivers stable performance over single‑mode fiber runs while the LC duplex connector ensures standard interoperability. Compatibility with 25G Ethernet makes the module suitable for server uplinks and switch interconnects, providing consistent throughput and link integrity under typical data center conditions.

Suitable for

• 25G Ethernet switch-to-switch and switch-to-server uplinks
• Data center top-of-rack and aggregation interconnects
• Service provider and enterprise single‑mode fiber links
• High‑density networking environments with SFP28 ports

Key specifications

• Form factor: SFP28 small form‑factor pluggable
• Data rate: 25 Gigabit per second
• Optical wavelength: 1310 nm
• Fiber type: single‑mode fiber (SMF)
• Connector: LC duplex
• Typical reach: short‑reach single‑mode links (vendor‑specified reach)
• Interface: serial 25G electrical interface compatible with SFP28 ports
• Power consumption: low power design suitable for high‑density deployments

How to use

Install the transceiver into an available SFP28 port on a compatible switch, server NIC or optical transponder until it seats firmly. Connect LC‑terminated single‑mode fiber patch cords to the module’s duplex LC connector following correct transmit/receive orientation. Verify link status and speed through the host device management interface; the module will negotiate the 25G link when the remote port supports the same rate. Follow equipment vendor guidance for hot‑plug handling and ESD precautions to avoid damage during insertion or removal.

Recommendations

For reliable operation, use single‑mode fiber with appropriate attenuation and quality, ensure LC connectors are clean before mating, and confirm host device firmware or operating system supports SFP28 25G optics. Avoid bending fiber beyond recommended radii and follow ambient temperature and power limits specified by the host equipment.
